ETERNAL PRINCIPLES

     Markets change,  but the principles of successful  investing do not. During
the past few years, radical upheaval in the stock market has displayed the power
of this simple truth to dramatic effect.
     In the late 1990s,  stocks  experienced one of the greatest bull markets in
financial  history.  Then, in March 2000,  the longest  downturn since the Great
Depression began.
     In both  bull and bear  markets,  however,  the  principles  of  successful
investing  are  identical:  balance,  diversification,  and  attention to costs.
Balance among stock, bond, and money market funds allows you to pursue long-term
growth while moderating your risk.  Diversification  limits your exposure to the
disasters  that can befall any one security or sector.  Attention to costs means
you keep a larger share of any rewards produced by your investments.
     These principles are timeless. In fact, they're the basis of our very first
mutual  fund--Vanguard(R)  Wellington(TM) Fund, a balanced portfolio established
in 1929. Over time, balance, diversification, and attention to costs have proven
to be the master keys to investment success.

SUMMARY
- --------------------------------------------------------------------------------
*    During  the  half-year,  Vanguard  Dividend  Growth  Fund  returned  16.5%,
     surpassing the average return of large-cap core funds but trailing the gain
     of the more growth-oriented Russell 1000 Index.

*    The  fund  earned  strong  returns  both in  dividend-rich  sectors  and in
     industries  such as technology  where  dividends  have  traditionally  been
     scarce.

*    The Jobs and Growth Tax Relief  Reconciliation  Act of 2003  provides  more
     favorable  tax  treatment  for  dividends,  a change  that  may  spur  more
     companies to start paying them.

JOHN J. BRENNAN

Fellow Shareholder,
During the six  months  ended  July 31,  2003,  Vanguard  Dividend  Growth  Fund
returned 16.5%,  surpassing the 15.6% average gain of large-cap core funds,  but
slightly  trailing  the 17.4%  return of the more  growth-oriented  Russell 1000
Index. Your fund's result reflected strong performance in dividend-rich  sectors
such as  financial  services  and producer  durables,  as well as in  technology
companies  considered to be potential  dividend-payers.  At the end of July, the
fund  provided  a  yield  of  1.8%.

INVESTORS' APPREHENSION TURNED TO OPTIMISM
At the start of the fiscal  half-year,  economic  uncertainty  and the impending
conflict with Iraq loomed large in the U.S. financial markets. By the end of the
period,  the mood had changed  from  apprehension  to optimism.  The  successful
military  campaign  in Iraq,  the  return  of  corporate  earnings  growth,  and
surprisingly positive economic reports, including better-than-expected growth in
U.S. output during the April-June quarter, drove stock prices higher.
     During the full six months, the broad U.S. stock market climbed nearly 19%.
Technology  stocks and other  growth-oriented  issues,  which had  sustained big
losses  during the past few years,  rebounded  strongly.  The  market's  smaller
stocks outpaced their larger  counterparts  as investors  demonstrated a renewed
appetite for risk.
     U.S.  investors  also earned good  returns in many  international  markets,
though  stock  performance  was only part of the  story.  A decline  in the U.S.
dollar's relative value transformed  mediocre euro- and pound-based results into
impressive dollar-denominated returns.

SHORT- AND LONGER-TERM INTEREST RATES WENT THEIR SEPARATE WAYS
By June  13,  continually  rising  bond  prices  had  trimmed  the  yield of the
benchmark  10-year U.S.  Treasury  note to a 45-year low of 3.11%.  In the weeks
that

1



followed,  however, rates rebounded,  and the yield of the 10-year Treasury note
closed the period at 4.41%.  For the full six  months,  rising  bond  yields and
falling  bond  prices  translated  into a total  return  of 0.3% for the  Lehman
Brothers  Aggregate Bond Index, a measure of the taxable  investment-grade  bond
market.

*Annualized.

     Short-term  interest  rates,  which  are more  directly  influenced  by the
Federal Reserve Board,  began the period low and finished lower. In an effort to
add fuel to the economic  expansion,  the Fed trimmed its target for the federal
funds  rate by 25 basis  points  (0.25  percentage  point)  to 1.00% at its June
meeting.  The 3-month U.S. Treasury bill, which typically follows Fed moves with
a lag, began the fiscal half-year at 1.17% and closed the period at 0.94%.

THE NEWLY POSITIONED FUND TURNED IN A STRONG SIX MONTHS
The past six months were Vanguard  Dividend Growth Fund's first fiscal half-year
with a new investment objective,  portfolio manager, and name. In December 2002,
shareholders in what was then Vanguard Utilities Income Fund voted to expand the
fund's  mandate to include a broader  universe of  securities,  and the name was
changed to reflect this shift in investment strategy. Since the debut of the new
strategy,  the broad stock market rallied powerfully and President Bush signed a
new law that enhances the after-tax attractiveness of dividends.
     Amid these  favorable  developments,  your fund produced  strong returns in
sectors of the market that have traditionally paid generous dividends--financial
services, materials & processing, and producer durables. The last of these three
includes  many old-line  industrial  companies  that are able to boost  dividend
payments when the business cycle rolls in their direction.
     Your fund also earned strong returns from technology  stocks,  a sector not
traditionally  associated with dividends,  but one that performed  exceptionally
well in the  six-month  period.  The fund's  new  mandate  allows  the  adviser,
Wellington  Management  Company,  to invest in companies that have the potential
and, in the adviser's judgment, a willingness to pay dividends. The

2


incentive  to do so has been made  stronger  by the new tax law,  which  accords
dividends the same favorable tax treatment as capital gains.
     Although the fund  exceeded  the average  return of  competing  funds,  its
return was slightly  behind that of the Russell 1000 Index.  This index reflects
the broad  spectrum  of  companies  that your  fund can  consider  under its new
mandate. The benchmark's fit is not quite perfect,  however,  given the Dividend
Growth Fund's slight emphasis on the market's more reasonably valued stocks.
     The fund's weakest result was in the consumer staples sector. These stocks,
which held up well through the stock market's long downturn, lost some ground in
recent  months as investors  turned  their  attention  to  previously  neglected
sectors.  The fund also earned below-market  returns (though they were excellent
in absolute terms) from some reliable dividend-payers in the oil and health care
sectors.

LESSONS FROM THE PAST
Long-suffering  stock investors  finally saw some reward for their patience when
equities  rebounded during the past  half-year--just as investors who stuck with
bonds during the booming 1990s were rewarded during the first three years of the
new  millennium.  Undoubtedly,  investors  who slept  soundest  throughout  both
periods  were those who  maintained  a portfolio  diversified  across and within
asset  classes,  and who  periodically  rebalanced  that  portfolio  back to the
original  target  allocation.  Such  investors got to enjoy a share of the gains
alternately  offered  by  stocks  and  by  bonds,  and  with  considerably  less
volatility than either asset class experienced on its own.
     Because  no one can  accurately  predict  the  direction  of the  financial
markets,  we have always believed that a balanced approach is the wisest course.
Vanguard  Dividend Growth Fund can be an important  component of such a plan for
investors generally,  and particularly for those seeking both capital growth and
income from their stock portfolios.
     Thank you for entrusting your hard-earned money to us.

Sincerely,

/S/ JOHN J. BRENNAN

REPORT FROM THE ADVISER
Vanguard  Dividend  Growth Fund  provided a 16.5%  return  during the six months
ended July 31, 2003, better than the 15.6% average return of competing large-cap
funds, but a bit behind the 17.4% return of the Russell 1000 Index.

THE INVESTMENT ENVIRONMENT
Stocks rose sharply during a period marked by market  volatility and significant
world events.  The relatively  short and successful Iraq war removed a source of
uncertainty  that had  weighed on the market  and  economy  earlier in the year.
Other risks and  uncertainties--high oil prices, the SARS virus, and weakness in
consumer  spending--all  appear to have  faded as we reached  midyear,  although
economic  indicators  were  still  mixed.  The  market  advance  was  relatively
broad-based, with the financial services, technology, and consumer discretionary
sectors leading the way. Typical  defensive  sectors such as energy and consumer
staples lagged during the period.
     May brought  the  passage of  President  Bush's tax reform  package,  which
lowered taxes on most dividends to 15%. Corporate reaction has been strong: More
companies initiated dividends or increased them during the first seven months of
2003  than  in all of  2002,  reversing  a  20-year  decline  in the  number  of
dividend-paying  companies.  We are pleased with this  development,  and we hope
that more  companies  will follow the example set by  Citigroup  (one of our top
holdings) by putting more  emphasis on returning  cash to  shareholders  through
dividends, and less emphasis on share repurchases.

THE FUND'S SUCCESSES
In returns relative to the benchmark,  our stock selection  provided its biggest
benefits  in  the  financial  and  industrial  sectors.   The  fund's  strongest
contributors during the period were Merrill Lynch, Citigroup, Intel, Home Depot,
McDonald's,  Guidant,  Caterpillar,  Apple Computer, Dover, and Alcoa.
     Companies  whose  stocks  represent  40% of  the  fund's  assets  increased
dividends  by more than 10% during the  half-year.  A number of these  companies
raised their  dividends by more than 20%; they included  Citigroup,  AT&T,  AIG,
Aventis, TJX Companies,  Total SA, Royal Dutch Petroleum,  Wachovia, Home Depot,
Bank One, and Knight Ridder. American Express raised its

                                            ------------------------------------
                                                           INVESTMENT PHILOSOPHY

                                              The adviser believes that the fund
                                                  can provide current income and
                                                 long-term growth of capital and
                                            income by investing in a diversified
                                                   portfolio of stocks that have
                                             excellent prospects for maintaining
                                                dividend payments and increasing
                                               earnings and dividends over time.
                                            ------------------------------------

dividend by 25%,  the  company's  first  increase in three  years.  Another fund
holding,  Guidant,  which had ceased paying dividends,  reinstated them. None of
the fund's holdings reduced dividends during the fiscal period.

THE FUND'S SHORTFALLS
The  Dividend  Growth Fund  underperformed  the Russell 1000 Index in the period
largely because, in comparison with the benchmark, we were under-weighted in two
sectors  that  performed  well:  technology  stocks and  consumer  discretionary
stocks.  So far in 2003,  a company's  dividend  policy has not had  significant
influence  on  the  way  its  stock   performed;   indeed,   non-dividend-payers
outperformed  dividend-payers  by a wide margin during the first seven months of
the year. We are confident,  however,  that steady,  growing dividends will be a
key contributor to the total returns of the fund's holdings over the long term.

THE FUND'S POSITIONING
It  seems  we  have  been  regularly  disappointed  in the  past  few  years  by
predictions  of a "second-half  recovery"  that never arrives.  At this point in
2003,  monetary and fiscal policies,  abetted by the U.S.  dollar's  weakness in
recent months,  are providing a level of stimulus that is  unprecedented  in the
last 30 years.  We are  cautiously  optimistic  that the recent tax reforms will
provide a modest boost to consumption  in the second half of 2003.  Historically
low interest rates should continue to provide  support for the economy.  We also
still hope to see a modest  amount of job  creation in the  remaining  months of
2003,  something  that  would  provide  the  seeds  for a  sustainable  economic
recovery.
     The  Dividend  Growth  Fund  continues  to be  positioned  for an  eventual
economic recovery with significant holdings in the energy, basic materials,  and
industrial  sectors.  The  fund's  holdings  in  the  financial  sector  reflect
continued improvement in the capital markets and continued strength in insurance
industry  fundamentals.  Our health care holdings combine attractive  valuations
with solid balance sheets,  strong cash flows,  strong  commitment to dividends,
and prospects for valuable product introductions.

GLOSSARY OF INVESTMENT TERMS

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation  to the ups and  downs of a  comparative  index and an  overall  market
index.  Each index is assigned a beta of 1.00.  Compared  with a given index,  a
fund with a beta of 1.20 typically  would have seen its share price rise or fall
by 12% when the index  rose or fell by 10%.  However,  a fund's  beta  should be
reviewed in conjunction with its R-squared (see definition below). The lower the
R-squared, the less correlation there is between the fund and the benchmark, and
the less reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
CASH  INVESTMENTS.  The  percentage  of a fund's  net assets  invested  in "cash
equivalents"--highly  liquid,  short-term,   interest-bearing  securities.  This
figure does not include cash invested in futures contracts or other equity index
products to simulate stock investment.
- --------------------------------------------------------------------------------
EARNINGS  GROWTH RATE.  The average  annual rate of growth in earnings  over the
past five years for the stocks now in a fund.
- --------------------------------------------------------------------------------
EXPENSE  RATIO.  The  percentage of a fund's  average net assets used to pay its
annual  administrative  and advisory  expenses.  These expenses  directly reduce
returns to investors.
- --------------------------------------------------------------------------------
FOREIGN HOLDINGS. The percentage of a fund's equity assets represented by stocks
or American Depositary Receipts of companies based outside the United States.
- --------------------------------------------------------------------------------
MEDIAN  MARKET  CAP.  An  indicator  of the  size of  companies  in which a fund
invests;  the  midpoint  of  market   capitalization   (market  price  x  shares
outstanding) of a fund's stocks, weighted by the proportion of the fund's assets
invested  in each  stock.  Stocks  representing  half of the fund's  assets have
market capitalizations above the median, and the rest are below it.
- --------------------------------------------------------------------------------
PRICE/BOOK  RATIO.  The share price of a stock divided by its net worth, or book
value,  per share.  For a fund,  the weighted  average  price/book  ratio of the
stocks it holds.
- --------------------------------------------------------------------------------
PRICE/EARNINGS  RATIO.  The ratio of a stock's  current  price to its  per-share
earnings over the past year. For a fund, the weighted  average P/E of the stocks
it holds. P/E is an indicator of market expectations about corporate  prospects;
the higher the P/E, the greater the expectations for a company's future growth.
- --------------------------------------------------------------------------------
R-SQUARED.  A measure of how much of a fund's past  returns can be  explained by
the returns from the market in general, as measured by a comparative index or an
overall market index. If a fund's total returns were precisely synchronized with
an index's  returns,  its R-squared would be 1.00. If the fund's returns bore no
relationship to the index's returns, its R-squared would be 0.
- --------------------------------------------------------------------------------
RETURN ON  EQUITY.  The annual  average  rate of return  generated  by a company
during the past five years for each dollar of  shareholder's  equity (net income
divided by  shareholder's  equity).  For a fund, the weighted  average return on
equity for the companies whose stocks it holds.
- --------------------------------------------------------------------------------
TURNOVER  RATE. An indication of the fund's  trading  activity.  Funds with high
turnover rates incur higher  transaction costs and are more likely to distribute
capital gains (which are taxable to investors).
- --------------------------------------------------------------------------------
YIELD.  A snapshot of a fund's  income from interest and  dividends.  The yield,
expressed  as a  percentage  of the fund's net asset  value,  is based on income
earned over the past 30 days and is  annualized,  or  projected  forward for the
coming  year.  The  index  yield  is  based on the  current  annualized  rate of
dividends paid on stocks in the index.

PERFORMANCE SUMMARY                                          As of July 31, 2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

FINANCIAL STATEMENTS                                   July 31, 2003 (unaudited)

STATEMENT OF NET ASSETS
This Statement  provides a detailed list of the fund's holdings,  including each
security's market value on the last day of the reporting period.  Securities are
grouped  and  subtotaled  by asset  type  (common  stocks,  bonds,  etc.) and by
industry sector. Other assets are added to, and liabilities are subtracted from,
the value of Total Investments to calculate the fund's Net Assets.  Finally, Net
Assets are divided by the outstanding  shares of the fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.
     At the end of the Statement of Net Assets, you will find a table displaying
the  composition  of the fund's net assets.  Because all income and any realized
gains must be  distributed  to  shareholders  each year,  the bulk of net assets
consists of Paid-in Capital (money invested by shareholders).  The amounts shown
for  Undistributed  Net  Investment  Income and  Accumulated  Net Realized Gains
usually   approximate   the  sums  the  fund  had  available  to  distribute  to
shareholders as income  dividends or capital gains as of the statement date, but
may  differ  because  certain   investments  or  transactions   may  be  treated
differently  for  financial  statement  and tax purposes.  Any  Accumulated  Net
Realized Losses,  and any cumulative excess of distributions  over net income or
net realized gains, will appear as negative  balances.  Unrealized  Appreciation
(Depreciation)  is the  difference  between  the  market  value  of  the  fund's
investments  and their  cost,  and  reflects  the gains  (losses)  that would be
realized if the fund were to sell all of its investments at their statement-date
values.

STATEMENT OF CHANGES IN NET ASSETS
This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the amount shareholders invested in the
fund,  either by purchasing shares or by reinvesting  distributions,  as well as
the amounts redeemed.  The  corresponding  numbers of Shares Issued and Redeemed
are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS
This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders  on a per- share basis. It also presents the Total Return and shows
net investment  income and expenses as percentages of average net assets.  These
data will help you assess:  the  variability  of the fund's net income and total
returns from year to year; the relative  contributions of net income and capital
gains to the fund's total return; how much it costs to operate the fund; and the
extent to which the fund tends to distribute capital gains. The table also shows
the Portfolio  Turnover Rate, a measure of trading activity.  A turnover rate of
100% means that the average security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS
Vanguard Dividend Growth Fund is registered under the Investment  Company Act of
1940 as an open-end investment company, or mutual fund.

A. The following  significant  accounting policies conform to generally accepted
accounting  principles for U.S. mutual funds. The fund consistently follows such
policies in preparing its financial statements.
     1.  SECURITY VALUATION: Securities are valued as of the close of trading on
the New York Stock Exchange  (generally 4:00 p.m. Eastern time) on the valuation
date. Equity securities are valued at the latest quoted sales prices or official
closing prices taken from the primary market in which each security trades; such
securities not traded on the valuation date are valued at the mean of the latest
quoted bid and asked  prices.  Securities  for which market  quotations  are not
readily  available,  or whose  values  have been  materially  affected by events
occurring  before the fund's pricing time but after the close of the securities'
primary  markets,  are  valued by  methods  deemed by the board of  trustees  to
represent  fair  value.  Temporary  cash  investments  acquired  over 60 days to
maturity are valued using the latest bid prices or using  valuations  based on a
matrix  system  (which  considers  such  factors  as  security  prices,  yields,
maturities,  and ratings),  both as furnished by independent  pricing  services.
Other  temporary  cash   investments   are  valued  at  amortized  cost,   which
approximates market value.
     2.  REPURCHASE  AGREEMENTS:  The fund,  along  with  other  members  of The
Vanguard Group,  transfers  uninvested cash balances into a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements  mature.  Each agreement  requires that
the market value of the  collateral be sufficient to cover  payments of interest
and principal; however, in the event of default or bankruptcy by the other party
to  the  agreement,  retention  of  the  collateral  may  be  subject  to  legal
proceedings.
     3.  FEDERAL  INCOME  TAXES:  The fund  intends to  continue to qualify as a
regulated   investment  company  and  distribute  all  of  its  taxable  income.
Accordingly,  no provision for federal income taxes is required in the financial
statements.
     4.  DISTRIBUTIONS:  Distributions  to  shareholders  are  recorded  on  the
ex-dividend date.
     5.  OTHER:  Dividend income is recorded on the ex-dividend  date.  Security
transactions  are accounted for on the date securities are bought or sold. Costs
used to determine  realized gains (losses) on the sale of investment  securities
are those of the specific securities sold.

B. Wellington  Management Company, llp, provides investment advisory services to
the fund for a fee  calculated  at an  annual  percentage  rate of  average  net
assets.  For the six months ended July 31, 2003, the advisory fee represented an
effective  annual rate of 0.10% of the fund's average net assets.  In accordance
with the advisory contract entered into with Wellington  Management  Company, in
May 2003, the investment  advisory fee will be subject to quarterly  adjustments
based  on the  performance  of the  fund  relative  to the  Russell  1000  Index
beginning February 1, 2004.

C. The Vanguard Group furnishes at cost corporate management, administrative,
marketing, and distribution services. The costs of such services are allocated
to the fund under methods approved by the board of trustees. The fund has
committed to provide up to 0.40% of its net assets in capital contributions to
Vanguard. At July 31, 2003, the fund had contributed capital of $108,000 to
Vanguard (included in Other Assets), representing 0.02% of the fund's net assets
and 0.11% of Vanguard's capitalization. The fund's trustees and officers are
also directors and officers of Vanguard.

15


D. The fund has asked its investment  adviser to direct certain security trades,
subject to obtaining the best price and execution, to brokers who have agreed to
rebate to the fund part of the  commissions  generated.  Such  rebates  are used
solely to reduce the fund's management and administrative  expenses. For the six
months ended July 31, 2003,  these  arrangements  reduced the fund's expenses by
$58,000 (an annual rate of 0.02% of average net assets).

E.  Distributions  are  determined  on a tax  basis  and  may  differ  from  net
investment income and realized capital gains for financial  reporting  purposes.
Differences   may  be  permanent  or  temporary.   Permanent   differences   are
reclassified among capital accounts in the financial statements to reflect their
tax  character.  Temporary  differences  arise  when  certain  items of  income,
expense,  gain,  or loss are  recognized  in  different  periods  for  financial
statement and tax purposes;  these  differences will reverse at some time in the
future.  Differences  in  classification  may also result from the  treatment of
short-term gains as ordinary income for tax purposes.
     The fund's  tax-basis  capital gains and losses are determined  only at the
end of each fiscal year.  For tax  purposes,  at January 31, 2003,  the fund had
available  realized losses of $211,257,000 to offset future net capital gains of
$70,259,000 through January 31, 2010,  $65,485,000 through January 31, 2011, and
$75,513,000  through January 31, 2012. The fund will use these capital losses to
offset net  taxable  capital  gains,  if any,  realized  during the year  ending
January 31, 2004;  should the fund realize net capital  losses for the year, the
losses will be added to the loss carryforward balances above.
     At July 31, 2003, net unrealized  appreciation of investment securities for
tax purposes was  $52,216,000,  consisting of unrealized gains of $65,264,000 on
securities  that had risen in value  since their  purchase  and  $13,048,000  in
unrealized losses on securities that had fallen in value since their purchase.

F. During the six months ended July 31, 2003, the fund purchased  $94,420,000 of
investment  securities and sold $82,694,000 of investment  securities other than
temporary cash  investments.

  for Vanguard Dividend Growth Fund

This  information  for the fiscal  year ended  January  31,  2003,  is  included
pursuant to provisions of the Internal Revenue Code:
     The fund intends to  distribute  the maximum  amount of qualified  dividend
income  allowable.  The amount of qualified  dividend income  distributed by the
fund will be provided to individual shareholders on their Form 1099-DIV.

THE PEOPLE WHO GOVERN YOUR FUND

The  trustees of your mutual fund are there to see that the fund is operated and
managed in your best interests since, as a shareholder,  you are a part owner of
the fund.  Your  fund  trustees  also  serve on the  board of  directors  of The
Vanguard  Group,  Inc.,  which is owned by the  Vanguard(R)  funds and  provides
services to them on an at-cost basis.
     A majority of Vanguard's board members are  independent,  meaning that they
have no  affiliation  with  Vanguard or the funds they  oversee,  apart from the
investments they have made as private individuals. Our independent board members
bring  distinguished  backgrounds in business,  academia,  and public service to
their task of working  with  Vanguard  officers to  establish  the  policies and
oversee the activities of the funds.
     Among board members' responsibilities are selecting investment advisers for
the  funds;  monitoring  fund  operations,  performance,  and  costs;  reviewing
contracts;  nominating  and  selecting  new  trustees/directors;   and  electing
Vanguard  officers.  The dates in  parentheses  below show when each trustee was
initially elected.

VANGUARD(R) ENERGY FUND
SEMIANNUAL REPORT
July 31, 2003

THE VANGUARD GROUP (R) LOGO


ETERNAL PRINCIPLES

Markets  change,  but the principles of successful  investing do not. During the
past few years,  radical upheaval in the stock market has displayed the power of
this simple truth to dramatic effect.

     In the late 1990s,  stocks  experienced one of the greatest bull markets in
financial  history.  Then, in March 2000,  the longest  downturn since the Great
Depression began.

     In both  bull and bear  markets,  however,  the  principles  of  successful
investing  are  identical:  balance,  diversification,  and  attention to costs.
Balance among stock, bond, and money market funds allows you to pursue long-term
growth while moderating your risk.  Diversification  limits your exposure to the
disasters  that can befall any one security or sector.  Attention to costs means
you keep a larger share of any rewards produced by your investments.

     These principles are timeless. In fact, they're the basis of our very first
mutual  fund--Vanguard(R)  Wellington(TM) Fund, a balanced portfolio established
in 1929. Over time, balance, diversification, and attention to costs have proven
to be the master keys to investment success.

Fellow Shareholder,

Stocks, both domestic and international, surged during the six months ended July
31,  2003.  With oil prices  falling,  energy  stocks did not keep pace with the
broad market,  but they still posted stellar returns.  For the first half of its
fiscal year,  Vanguard Energy Fund earned 11.2%,  outperforming both the average
natural resources mutual fund and an unmanaged index for the energy sector.

INVESTORS' APPREHENSION TURNED TO OPTIMISM

At the start of the fiscal  half-year,  economic  uncertainty  and the impending
conflict with Iraq loomed large in the U.S. financial markets. By the end of the
period,  the mood had changed  from  apprehension  to optimism.  The  successful
military  campaign  in Iraq,  the  return  of  corporate  earnings  growth,  and
surprisingly positive economic reports, including better-than-expected growth in
U.S. output during the April-June quarter, drove stock prices higher.

     During the full six months, the broad U.S. stock market climbed nearly 19%.
Technology  stocks and other  growth-oriented  issues,  which had  sustained big
losses  during the past few years,  rebounded  strongly.  The  market's  smaller
stocks outpaced their larger  counterparts  as investors  demonstrated a renewed
appetite for risk.

     U.S.  investors  also earned good  returns in many  international  markets,
though  stock  performance  was only part of the  story.  A decline  in the U.S.
dollar's  relative  value  transformed  mediocre  euro- and British  pound-based
results into impressive dollar-denominated returns.

SHORT- AND LONGER-TERM INTEREST RATES WENT THEIR SEPARATE WAYS

By June  13,  continually  rising  bond  prices  had  trimmed  the  yield of the
benchmark  10-year U.S.  Treasury  note to a 45-year low of 3.11%.  In the weeks
that followed,  however, rates rebounded,  and the yield of the 10-year Treasury
note closed the period at 4.41%. For the full six months, rising bond yields and
falling  bond  prices  translated  into a total  return  of 0.3% for the  Lehman
Brothers  Aggregate Bond Index, a measure of the taxable  investment-grade  bond
market.

     Short-term  interest  rates,  which  are more  directly  influenced  by the
Federal Reserve Board,  began the period low and finished lower. In an effort to
add fuel to the economic  expansion,  the Fed trimmed its target for the federal
funds  rate by 25 basis  points  (0.25  percentage  point)  to 1.00% at its June
meeting.  The 3-month U.S. Treasury bill, which typically follows Fed moves with
a lag, began the fiscal half-year at 1.17% and closed the period at 0.94%.

ENERGY PRICES DROPPED A BIT BUT REMAINED HIGH

During the buildup to the war with Iraq, oil prices skyrocketed, reaching a peak
of $38 a barrel in February.  But once the war started,  prices declined. By the
end of the  fiscal  half-year,  crude oil cost  about  $31 a barrel.  Meanwhile,
natural gas prices were even more  volatile  due to limited  supplies and a cold
winter.  Despite the spikes,  in  aggregate,  energy  prices fell during the six
months, though they remained well above their levels of 12 months earlier.

     Energy price dynamics  played out  differently  in the  industry's  various
subsectors.  Overall,  declining  prices proved  beneficial  to  integrated  oil
companies--those that are involved in drilling, refining, and retail operations.
For these companies, if falling prices for raw materials hurt one business line,
the same lower prices will  benefit  another  business  line by  increasing  its
profit  margins.  The integrated  oil giants were the fund's biggest  subsector,
averaging  about 42% of assets in the period,  and they  contributed the most to
its  semiannual  performance  both in absolute terms and relative to benchmarks.
Illustrating the

                                       2




benefit of good stock selection,  the fund's  integrated oil holdings gained 13%
during the six months,  compared with an 8% return for the same subsector in the
Standard & Poor's Energy Sector Index.

     Even after the  declines,  energy  prices  remained  at  historically  high
levels,  supporting the earnings of exploration  and production  companies.  The
Energy  Fund had  more  than  one-third  of its  assets  in such  stocks,  which
collectively  gained  9%.  Also  boosting  returns  for  your  fund was the U.S.
dollar's decline, which augmented returns from foreign securities.  Indeed, half
of the top ten contributors to your fund's six-month return were companies based
outside the United States.

     More  details on the fund's  performance  and its  individual  holdings are
provided in the Report from the Adviser on page 5.

LESSONS  FROM THE PAST

Long-suffering  stock investors  finally saw some reward for their patience when
equities  rebounded during the past  half-year--just as investors who stuck with
bonds during the booming 1990s  eventually  were rewarded during the first years
of the new millennium.  Undoubtedly,  the investor who slept soundest throughout
both periods was one who  maintained a portfolio  diversified  across and within
asset  classes,  and who  periodically  rebalanced  that  portfolio  back to the
original  target  allocation.  Such  investors got to enjoy a share of the gains
alternately  offered  by  stocks  and  by  bonds,  and  with  considerably  less
volatility than either asset class experienced on its own.

     Because  no one can  accurately  predict  the  direction  of the  financial
markets,  we have always believed that a balanced approach is the wisest course.
Sector funds such as Vanguard Energy Fund can add value by further  diversifying
an already  well-balanced  portfolio  or by serving  as a modest  investment  to
support  your  conviction  that a  particular  industry  will  outpace the broad
market.

     Thank you for entrusting your hard-earned money to us.

REPORT FROM THE ADVISER

Vanguard  Energy Fund returned  11.2% during the six months ended July 31, 2003.
The average  natural  resources  fund  returned 9.1% and the Wilshire 5000 Index
18.6% during the same period.

THE  INVESTMENT  ENVIRONMENT

Energy  stocks were helped over the last six months by robust  commodity  prices
and a more speculative mood in the equity market. Oil prices stayed close to $30
a barrel most of the time as OPEC continued to manage output to keep inventories
low.

     Natural gas prices also remained  high,  exceeding  $10 per thousand  cubic
feet in late  February  and staying  above $5 per thousand  cubic feet  (roughly
twice the ten-year  average)  for much of the six months.  The lofty prices have
been  sustained  by a  supply-demand  imbalance;  for  example,  at  the  end of
February,  natural  gas  inventories  were less than half what they had been the
prior year.

OUR  SUCCESSES

The fund  benefited  from the return to favor of refining and  marketing  stocks
Sunoco and Ashland. Other top performers--Norsk  Hydro, Petrol Brasil,  Canadian
Natural Resources,  and Sinopec (China Petroleum and  Chemical)--had  nothing in
common except being based outside the United States.

OUR SHORTFALLS

Thanks to the robust environment,  none of the fund's holdings detracted notably
from returns in the half-year. Among stocks that performed less well than others
were  Transocean and  GlobalSantaFe,  both in the business of offshore  drilling
rigs. The use of and pricing for offshore rigs has been  disappointing  over the
past year.

- --------------------------------------------------------------------------------
INVESTMENT PHILOSOPHY

This  fund  reflects  a belief  that  investors  who seek to  emphasize  a given
economic  sector as part of a long-term,  balanced  investment  program are best
served by holding a portfolio of securities well-diversified across that sector.
- --------------------------------------------------------------------------------

THE FUND'S POSITIONING

The fund continues to emphasize energy stocks that offer good  opportunities for
long-term  total return.  The  subsectors  represented  in its holdings  include
international  oils,  foreign  integrated  oils and  producers,  North  American
producers,  oil  service  and  equipment,  transmission  and  distribution,  and
refining  and  marketing.  Over the past six  months,  the fund has  reduced its
exposure to oil service and equipment companies and to

                                       5


refining and marketing companies,  while increasing exposure to producers and to
international oil firms.

GLOSSARY OF INVESTMENT TERMS

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation  to the ups and downs of the  overall  market  (or  appropriate  market
index).  The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20  typically  would have seen its share price rise or fall by 12% when the
overall market rose or fell by 10%. However, a fund's beta should be reviewed in
conjunction with its R-squared (see definition  below). The lower the R-squared,
the less correlation  there is between the fund and the benchmark,  and the less
reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
CASH  INVESTMENTS.  The  percentage  of a fund's  net assets  invested  in "cash
equivalents"--highly  liquid,  short-term,   interest-bearing  securities.  This
figure does not include cash invested in futures contracts or other equity index
products to simulate stock investment.
- --------------------------------------------------------------------------------
EARNINGS  GROWTH RATE.  The average  annual rate of growth in earnings  over the
past five years for the stocks now in a fund.
- --------------------------------------------------------------------------------
EXPENSE  RATIO.  The  percentage of a fund's  average net assets used to pay its
annual  administrative  and advisory  expenses.  These expenses  directly reduce
returns to investors.
- --------------------------------------------------------------------------------
FOREIGN HOLDINGS. The percentage of a fund's equity assets represented by stocks
or American Depositary Receipts of companies based outside the United States.
- --------------------------------------------------------------------------------
MEDIAN  MARKET  CAP.  An  indicator  of the  size of  companies  in which a fund
invests;  the  midpoint  of  market   capitalization   (market  price  x  shares
outstanding) of a fund's stocks, weighted by the proportion of the fund's assets
invested  in each  stock.  Stocks  representing  half of the fund's  assets have
market capitalizations above the median, and the rest are below it.
- --------------------------------------------------------------------------------
PRICE/BOOK  RATIO.  The share price of a stock divided by its net worth, or book
value,  per share.  For a fund,  the weighted  average  price/book  ratio of the
stocks it holds.
- --------------------------------------------------------------------------------
PRICE/EARNINGS  RATIO.  The ratio of a stock's  current  price to its  per-share
earnings over the past year. For a fund, the weighted  average P/E of the stocks
it holds. P/E is an indicator of market expectations about corporate  prospects;
the higher the P/E, the greater the expectations for a company's future growth.
- --------------------------------------------------------------------------------
R-SQUARED.  A measure of how much of a fund's past  returns can be  explained by
the returns from the overall market (or its benchmark  index). If a fund's total
returns  were  precisely  synchronized  with the overall  market's  return,  its
R-squared  would be 1.00.  If the fund's  returns  bore no  relationship  to the
market's returns, its R-squared would be 0.
- --------------------------------------------------------------------------------
RETURN ON  EQUITY.  The annual  average  rate of return  generated  by a company
during the past five years for each dollar of  shareholder's  equity (net income
divided by  shareholder's  equity).  For a fund, the weighted  average return on
equity for the companies whose stocks it holds.
- --------------------------------------------------------------------------------
TURNOVER  RATE. An indication of the fund's  trading  activity.  Funds with high
turnover rates incur higher  transaction costs and are more likely to distribute
capital gains (which are taxable to investors).
- --------------------------------------------------------------------------------
YIELD.  A snapshot of a fund's  income from interest and  dividends.  The yield,
expressed  as a  percentage  of the fund's net asset  value,  is based on income
earned over the past 30 days and is  annualized,  or  projected  forward for the
coming  year.  The  index  yield  is  based on the  current  annualized  rate of
dividends paid on stocks in the index.

PERFORMANCE SUMMARY                                          AS OF JULY 31, 2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

FINANCIAL STATEMENTS                                   JULY 31, 2003 (UNAUDITED)

STATEMENT OF NET ASSETS

This Statement  provides a detailed list of the fund's holdings,  including each
security's market value on the last day of the reporting period.  Securities are
grouped and subtotaled by asset type (common stocks,  bonds, etc.) and by sector
within the fund's designated industry; international securities, if significant,
may be presented in a separate group. Other assets are added to, and liabilities
are subtracted from, the value of Total  Investments to calculate the fund's Net
Assets. Finally, Net Assets are divided by the outstanding shares of the fund to
arrive at its share price, or Net Asset Value (NAV) Per Share.

     At the end of the Statement of Net Assets, you will find a table displaying
the  composition  of the fund's net assets.  Because all income and any realized
gains must be  distributed  to  shareholders  each year,  the bulk of net assets
consists of Paid-in Capital (money invested by shareholders).  The amounts shown
for  Undistributed  Net  Investment  Income and  Accumulated  Net Realized Gains
usually   approximate   the  sums  the  fund  had  available  to  distribute  to
shareholders as income  dividends or capital gains as of the statement date, but
may  differ  because  certain   investments  or  transactions   may  be  treated
differently  for  financial  statement  and tax purposes.  Any  Accumulated  Net
Realized Losses,  and any cumulative excess of distributions  over net income or
net realized gains, will appear as negative  balances.  Unrealized  Appreciation
(Depreciation)  is the  difference  between  the  market  value  of  the  fund's
investments  and their  cost,  and  reflects  the gains  (losses)  that would be
realized if the fund were to sell all of its investments at their statement-date
values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the net amount shareholders invested in
or redeemed  from the fund.  Distributions  and Capital Share  Transactions  are
shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders on a per-share basis for each class of shares. It also presents the
Total  Return and shows net  investment  income and expenses as  percentages  of
average net  assets.  These data will help you assess:  the  variability  of the
fund's  net  income  and  total   returns  from  year  to  year;   the  relative
contributions  of net income and capital gains to the fund's total  return;  how
much it costs to  operate  the fund;  and the  extent to which the fund tends to
distribute  capital gains.  The table also shows the Portfolio  Turnover Rate, a
measure of trading  activity.  A  turnover  rate of 100% means that the  average
security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Energy Fund is registered  under the Investment  Company Act of 1940 as
an  open-end  investment  company,  or  mutual  fund.  The  fund may  invest  in
securities  of foreign  issuers,  which may subject it to  investment  risks not
normally associated with investing in securities of United States  corporations.
The fund  offers two  classes of shares,  Investor  Shares and  Admiral  Shares.
Investor  Shares are  available  to any  investor  who meets the fund's  minimum
purchase  requirements.  Admiral  Shares are  designed  for  investors  who meet
certain administrative, servicing, tenure, and account- size criteria.

A. The following  significant  accounting policies conform to generally accepted
accounting  principles for U.S. mutual funds. The fund consistently follows such
policies in preparing its financial statements.

     1. Security Valuation:  Securities are valued as of the close of trading on
the New York Stock Exchange  (generally 4:00 p.m. Eastern time) on the valuation
date. Equity securities are valued at the latest quoted sales prices or official
closing prices taken from the primary market in which each security trades; such
securities not traded on the valuation date are valued at the mean of the latest
quoted bid and asked  prices.  Securities  for which market  quotations  are not
readily  available,  or whose  values  have been  materially  affected by events
occurring  before the fund's pricing time but after the close of the securities'
primary  markets,  are  valued by  methods  deemed by the board of  trustees  to
represent  fair  value.  Temporary  cash  investments  acquired  over 60 days to
maturity are valued using the latest bid prices or using  valuations  based on a
matrix  system  (which  considers  such  factors  as  security  prices,  yields,
maturities,  and ratings),  both as furnished by independent  pricing  services.
Other  temporary  cash   investments   are  valued  at  amortized  cost,   which
approximates market value.

     2.  Foreign   Currency:   Securities  and  other  assets  and   liabilities
denominated  in  foreign  currencies  are  translated  into U.S.  dollars at the
exchange  rates on the  valuation  date as  employed by Morgan  Stanley  Capital
International in the calculation of its indexes.

     Realized  gains  (losses) and  unrealized  appreciation  (depreciation)  on
investment securities include the effects of changes in exchange rates since the
securities  were  purchased,  combined  with the  effects of changes in security
prices. Fluctuations in the value of other assets and liabilities resulting from
changes in exchange  rates are recorded as  unrealized  foreign  currency  gains
(losses) until the asset or liability is settled in cash, when they are recorded
as realized foreign currency gains (losses).

     3.  Repurchase  Agreements:  The fund,  along  with  other  members  of The
Vanguard  Group,  transfers  uninvested  cash balances to a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements  mature.  Each agreement  requires that
the market value of the  collateral be sufficient to cover  payments of interest
and principal; however, in the event of default or bankruptcy by the other party
to  the  agreement,  retention  of  the  collateral  may  be  subject  to  legal
proceedings.

     4.  Federal  Income  Taxes:  The fund  intends to  continue to qualify as a
regulated   investment  company  and  distribute  all  of  its  taxable  income.
Accordingly,  no provision for federal income taxes is required in the financial
statements.

     5.  Distributions:  Distributions  to  shareholders  are  recorded  on  the
ex-dividend date.

     6. Other:  Dividend  income is recorded on the ex-dividend  date.  Security
transactions  are accounted for on the date securities are bought or sold. Costs
used to determine  realized gains (losses) on the sale of investment  securities
are those of the specific  securities  sold.  Fees  assessed on  redemptions  of
capital shares are credited to paid-in capital.

Each class of shares has equal  rights as to assets and  earnings,  except  that
each  class  separately  bears  certain   class-specific   expenses  related  to
maintenance of shareholder  accounts  (included


                                       17


NOTES TO FINANCIAL STATEMENTS (CONTINUED)

in Management and Administrative expenses) and shareholder reporting.  Marketing
and  distribution  expenses  are  allocated  to each class of shares  based on a
method  approved  by the board of  trustees.  Income,  other  non-class-specific
expenses,  and gains and losses on  investments  are  allocated to each class of
shares based on its relative net assets.

B. Wellington  Management Company, llp, provides investment advisory services to
the fund for a fee  calculated  at an  annual  percentage  rate of  average  net
assets.  For the six months ended July 31, 2003, the advisory fee represented an
effective annual rate of 0.06% of the fund's average net assets.

C. The Vanguard Group  furnishes at cost corporate  management,  administrative,
marketing,  and distribution  services. The costs of such services are allocated
to the fund  under  methods  approved  by the  board of  trustees.  The fund has
committed to provide up to 0.40% of its net assets in capital  contributions  to
Vanguard.  At July 31,  2003,  the fund had  contributed  capital of $306,000 to
Vanguard (included in Other Assets), representing 0.02% of the fund's net assets
and 0.31% of  Vanguard's  capitalization.  The fund's  trustees and officers are
also directors and officers of Vanguard.

D. The fund has asked its investment  adviser to direct certain security trades,
subject to obtaining the best price and execution, to brokers who have agreed to
rebate to the fund part of the  commissions  generated.  Such  rebates  are used
solely to reduce the fund's management and administrative  expenses.  The fund's
custodian  bank has also agreed to reduce its fees when the fund  maintains cash
on deposit in the non-interest-bearing custody account. For the six months ended
July 31, 2003, directed brokerage and custodian fee offset arrangements  reduced
expenses  by $180,000  and $1,000,  respectively.  The total  expense  reduction
represented an effective annual rate of 0.02% of the fund's average net assets.

E.  Distributions  are  determined  on a tax  basis  and  may  differ  from  net
investment income and realized capital gains for financial  reporting  purposes.
Differences   may  be  permanent  or  temporary.   Permanent   differences   are
reclassified among capital accounts in the financial statements to reflect their
tax  character.  Temporary  differences  arise  when  certain  items of  income,
expense,  gain,  or loss are  recognized  in  different  periods  for  financial
statement and tax purposes;  these  differences will reverse at some time in the
future.  Differences  in  classification  may also result from the  treatment of
short-term gains as ordinary income for tax purposes.

     During the six months  ended July 31, 2003,  the fund  realized net foreign
currency  losses of $38,000,  which decreased  distributable  net income for tax
purposes;  accordingly,  such losses have been reclassified from accumulated net
realized gains to undistributed net investment income.

     The fund's  tax-basis  capital gains and losses are determined  only at the
end of each fiscal year.  For tax  purposes,  at January 31, 2003,  the fund had
available  realized  losses of  $5,726,000  to offset  future net capital  gains
through  January 31, 2012.  The fund will use these capital losses to offset net
taxable capital gains, if any, realized during the year ending January 31, 2004;
should the fund  realize  net  capital  losses for the year,  the losses will be
added to the loss carryforward balance above.

     At July 31, 2003, net unrealized  appreciation of investment securities for
tax purposes was $217,809,000, consisting of unrealized gains of $268,871,000 on
securities  that had risen in value  since their  purchase  and  $51,062,000  in
unrealized losses on securities that had fallen in value since their purchase.

The fund had net unrealized  foreign currency gains of $6,000 resulting from the
translation of other assets and  liabilities at July 31, 2003.


                                       18


F. During the six months ended July 31, 2003, the fund purchased $436,800,000 of
investment  securities and sold $280,949,000 of investment securities other than
temporary cash investments.

G. The market value of  securities on loan to  broker/dealers  at July 31, 2003,
was $103,264,000,  for which the fund held cash collateral of $106,545,000.  The
fund invests cash collateral  received in repurchase  agreements,  and records a
liability for the return of the collateral, during the period the securities are
on loan.

H. Capital share transactions for each class of shares were:

THE PEOPLE WHO GOVERN YOUR FUND

The  trustees of your mutual fund are there to see that the fund is operated and
managed in your best interests since, as a shareholder,  you are a part owner of
the fund.  Your  fund  trustees  also  serve on the  board of  directors  of The
Vanguard  Group,  Inc.,  which is owned by the  Vanguard(R)  funds and  provides
services to them on an at-cost basis.

     A majority of Vanguard's board members are  independent,  meaning that they
have no  affiliation  with  Vanguard or the funds they  oversee,  apart from the
investments they have made as private individuals. Our independent board members
bring  distinguished  backgrounds in business,  academia,  and public service to
their task of working  with  Vanguard  officers to  establish  the  policies and
oversee the activities of the funds.

     Among board members' responsibilities are selecting investment advisers for
the  funds;  monitoring  fund  operations,  performance,  and  costs;  reviewing
contracts;  nominating  and  selecting  new  trustees/directors;   and  electing
Vanguard  officers.  The dates in  parentheses  below show when each trustee was
initially elected.

ETERNAL PRINCIPLES

     Markets change,  but the principles of successful  investing do not. During
the past few years, radical upheaval in the stock market has displayed the power
of this simple truth to dramatic effect.

     In the late 1990s,  stocks  experienced one of the greatest bull markets in
financial  history.  Then, in March 2000,  the longest  downturn since the Great
Depression began.

     In both  bull and bear  markets,  however,  the  principles  of  successful
investing  are  identical:  balance,  diversification,  and  attention to costs.
Balance among stock, bond, and money market funds allows you to pursue long-term
growth while moderating your risk.  Diversification  limits your exposure to the
disasters  that can befall any one security or sector.  Attention to costs means
you keep a larger share of any rewards produced by your investments.

     These principles are timeless. In fact, they're the basis of our very first
mutual  fund--Vanguard(R)  Wellington(TM) Fund, a balanced portfolio established
in 1929. Over time, balance, diversification, and attention to costs have proven
to be the master keys to investment success.

Fellow Shareholder,

Vanguard Precious Metals Fund returned 5.3% for the first half of fiscal 2004, a
period in which the prices of some precious  metals dipped slightly while others
increased  modestly.  The fund's  performance  benefited from the decline of the
U.S. dollar,  as much of the portfolio is invested  abroad.  For the six months,
the Precious Metals Fund  outperformed its average peer but lagged its benchmark
index,  largely  because  of  the  fund's  broad   diversification   across  the
precious-metals sector.

INVESTORS' APPREHENSION TURNED TO OPTIMISM

At the start of the fiscal  half-year,  economic  uncertainty  and the impending
conflict with Iraq loomed large in the U.S. financial markets. By the end of the
period,  the mood had changed  from  apprehension  to optimism.  The  successful
military  campaign  in Iraq,  the  return  of  corporate  earnings  growth,  and
surprisingly positive economic reports, including better-than-expected growth in
U.S. output during the April-June quarter, drove stock prices higher.

     As the Wilshire 5000 Total Market Index  climbed  toward its gain of nearly
19%, technology stocks and other growth-oriented issues, which had sustained big
losses  during the past few years,  rebounded  strongly.  The  market's  smaller
stocks outpaced their larger  counterparts  as investors  demonstrated a renewed
appetite for risk.

     U.S.  investors  also earned good  returns in many  international  markets,
though  stock  performance  was only part of the  story.  A decline  in the U.S.
dollar's  relative  value  transformed  mediocre  euro- and British  pound-based
results  into  impressive  dollar-denominated  returns.

SHORT- AND  LONGER-TERM INTEREST  RATES WENT THEIR  SEPARATE  WAYS

By June  13,  continually  rising  bond  prices  had  trimmed  the  yield of the
benchmark  10-year U.S.  Treasury  note to a 45-year low of 3.11%.  In the weeks
that followed,  however, rates rebounded,  and the yield of the 10-year Treasury
note closed the period at 4.41%.  For the full six months,  the Lehman  Brothers
Aggregate  Bond Index,  a measure of the taxable  investment-grade  bond market,
returned 0.3%.

     Short-term  interest  rates,  which  are more  directly  influenced  by the
Federal Reserve Board,  began the period low and finished lower. In an effort to
add fuel to the economic  expansion,  the Fed trimmed its target for the federal
funds  rate by 25 basis  points  (0.25  percentage  point)  to 1.00% at its June
meeting.

THE FUND SAW MIXED RESULTS FROM GOLD AND  NON-GOLD  HOLDINGS

The fund's  return for the first half of the 2004 fiscal  year was  respectable,
despite  its  shortfall  relative  to its  benchmark.  The  period was marked by
continuing  consolidation in the precious-metals  industry. With few exceptions,
stocks of  companies  involved in seeking out,  mining,  and  distributing  gold
produced solid returns,  which often were augmented for U.S.-based  investors by
the dollar's decline. Among the fund's top performers in this group were Ashanti
Goldfields,   a  large  Ghanaian  mining   operation,   and  Compania  de  Minas
Buenaventura, a Peruvian mining firm.

     The Precious Metals Fund underperformed its market benchmark, the Citigroup
World Equity Gold Index,  because of the fund's sizable investments in companies
not involved with gold. To avoid the risks associated with an exclusive focus on
gold-related   stocks,   the  fund's  adviser  maintains  a  portfolio  that  is
diversified  across the  precious-metals  industry.  The fund's holdings include
issues from companies  involved in the mining,  processing,  and distribution of
silver, platinum, palladium, copper, and diamonds. Although this diversification
is a benefit in times when gold stocks are out of favor,  it  hindered  the fund
somewhat during the past six months. For instance, the


                                       2


stocks of Impala Platinum Holdings (the fund's second-largest holding as of July
31, at nearly 10% of assets) and Anglo American  Platinum both declined notably,
despite rising prices for platinum in the period.

     Although a conservative approach to the volatile precious-metals sector may
seem  something of a  contradiction  in terms,  we continue to  believe--as  the
adviser  does--that  broad  diversification  across the  industry  is one key to
success for long-term investors. Low cost is another. The Precious Metals Fund's
low  costs  ensure  that  more of the  rewards  of this  strategy  remain in the
accounts of  shareholders.  Your  fund's  annualized  expense  ratio of 0.60% of
average net assets  ($6.00 per $1,000 in assets) is much  smaller than the 1.93%
($19.30 per $1,000 in assets) charged by the average mutual fund competitor.

MAINTAIN A LONG-TERM PERSPECTIVE ON YOUR INVESTMENT PLAN

Given the fund's  excellent  performance  over the past three years,  a reminder
about the  significant  risks it entails seems in order.  From July 31, 2000, to
July 31, 2003, the fund returned a cumulative 99.2%,  while the broad U.S. stock
market shed about a quarter of its value.  However,  when we look farther  back,
the risk is apparent: Over the ten years ended July 31, 2003, the fund's average
annual return of 1.3% fell well short of the broader market's 9.8% return.  Over
that decade, the fund's best July-to-July  result was a gain of 33.0% for the 12
months ended July 31, 2003;  and its worst was a decline of -34.0% in 1997-1998.
Given the  concentrated  nature of the fund,  investors should expect such sharp
ups and downs. We appreciate the persistence  that our  shareholders  display in
riding out this sort of volatility.

     Nobody,  not even the most  skilled  market-watcher,  knows what the future
holds  for  any  asset  class--a  universal  truth  that  seems  even  truer  in
precious-metals investing.  That's why Vanguard has always advocated a balanced,
long-term  investment approach that includes the appropriate mix of stock, bond,
and money market funds for your unique goals, financial circumstances,  and risk
tolerance.  Vanguard  Precious  Metals Fund can be a small  component  of such a
plan,  providing an opportunity to diversify a stock portfolio made up of mutual
funds that invest in more mainstream industries.

     Thank you for your continued confidence in Vanguard.


Sincerely,

REPORT FROM THE ADVISER

Vanguard Precious Metals Fund returned 5.3% during the six months ended July 31,
2003. The fund  outperformed  its average mutual fund peer, which rose 5.0%, but
lagged the Citigroup World Equity Gold Index, which returned 6.6%.

THE INVESTMENT  ENVIRONMENT

The  price of gold  reached  a  six-year  high of $381 an ounce at the  start of
February,  before falling on expectations of a swift  resolution to the military
operations in Iraq.  The price,  however,  recovered  following the end of major
hostilities  in April,  and  remained  surprisingly  strong  for the rest of the
period.  The ongoing  strength  can be explained by  investors'  concerns  about
further weakness in the U.S. dollar,  as well as by fewer gold producers locking
in prices in advance (known as "hedging").  Ongoing industry  consolidation  has
also played a role.

     Our  gold-mining  holdings  provided a wide array of returns during the six
months.  While a number of pure,  liquid,  "unhedged"  stocks  (such as  Newmont
Mining and Compania de Minas  Buenaventura)  made strong gains,  other  holdings
(such as AngloGold and Harmony Gold Mining)  underperformed.  Minas Buenaventura
did particularly well for us, but our  underweighting in Newmont Mining compared
with the index detracted from relative returns.

     A little more on our Newmont  positioning  is  warranted  here.  Before the
three-way merger of Newmont, Franco-Nevada, and Normandy Mining in 2002, we held
all  three  companies,  and the  portfolio  benefited  considerably  from  these
holdings.  The combined entity became the world's largest  gold-mining  company,
making up a  considerable  proportion  of the index.  But because the  valuation
seems stretched  following strong post-merger gains and because we have concerns
about the  Normandy  Mining  part of the  group,  we have since sold most of our
holdings.

- --------------------------------------------------------------------------------
INVESTMENT PHILOSOPHY

The fund  reflects  the belief that  investors  who seek to  emphasize  precious
metals  stocks as part of a  long-term,  balanced  investment  program  are best
served by holding a low-cost portfolio of carefully  selected  securities in the
sector.
- --------------------------------------------------------------------------------

     We  continued  to take  advantage  of  industry  consolidation.  Australian
gold-mining company Abelle, in which we had a small holding, received a bid from
Harmony  Gold,  and we  eliminated  our  position  following a rise in its stock
price.  Toward the end of the period,  Ghana-based Ashanti Goldfields received a
bid from South Africa's AngloGold and a counterbid from  London-listed  Randgold
Resources. The resulting


                                       5


price appreciation made Ashanti the largest contributor to our half-year return.
Our holding of platinum miner Lonmin, which owns 27% of Ashanti, also benefited.

     Elsewhere,  we saw good returns from our diversified  mining companies.  In
particular,  strong  contributions  to our  relative  returns  came from Norilsk
Nickel  and Rio  Tinto.  Aber  Diamond  also did  well.

     The price of platinum  continued  to rise during the six months,  but South
African  producers were affected by concerns about the impact of the strength of
the local currency,  the rand, on earnings.  Our holdings of Impala Platinum and
Anglo  American  Platinum  did  poorly.   Nevertheless,   we  believe  that  the
supply-and-demand scenario bodes well and that platinum miners remain attractive
values relative to their gold-mining counterparts.

SEVERAL NEW HOLDINGS WERE ADDED

We added several new holdings during the period,  including diamond  exploration
and mining  company  SouthernEra  Resources and  diversified  mining company WMC
Resources.  We also added gold  companies  First  Quantum  Minerals and Meridian
Gold, and increased our holdings of Lonmin,  all at attractive price levels.  We
sold our entire position in Inco and, as noted,  the majority of our holdings of
Newmont Mining,  capturing strong relative returns. We also reduced our position
in major  gold-miner  Placer Dome,  which became a large  holding  following its
takeover of AurionGold.

OUR FOCUS ON FUNDAMENTALS IS UNCHANGED

Going forward,  we remain  confident about the outlook for gold prices against a
backdrop of weakness in the U.S. dollar, industry consolidation,  and heightened
geopolitical tensions. However, we are becoming increasingly concerned about the
valuations of gold-mining  companies,  especially given the poor performance and
increased issuance of stock we have seen from some companies.  Regardless of the
market's apparent lack of concern about valuations in many instances,  we remain
focused  on  companies   with  strong   fundamentals   and   consistent  in  our
valuation-driven approach to investment.

GLOSSARY OF INVESTMENT TERMS

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation  to the ups and downs of the  overall  market  (or  appropriate  market
index).  The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20  typically  would have seen its share price rise or fall by 12% when the
overall market rose or fell by 10%. However, a fund's beta should be reviewed in
conjunction with its R-squared (see definition  below). The lower the R-squared,
the less correlation  there is between the fund and the benchmark,  and the less
reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
CASH  INVESTMENTS.  The  percentage  of a fund's  net assets  invested  in "cash
equivalents"--highly  liquid,  short-term,   interest-bearing  securities.  This
figure does not include cash invested in futures contracts or other equity index
products to simulate stock investment.
- --------------------------------------------------------------------------------
EARNINGS  GROWTH RATE.  The average  annual rate of growth in earnings  over the
past five years for the stocks now in a fund.
- --------------------------------------------------------------------------------
EXPENSE  RATIO.  The  percentage of a fund's  average net assets used to pay its
annual  administrative  and advisory  expenses.  These expenses  directly reduce
returns to investors.
- --------------------------------------------------------------------------------
FOREIGN HOLDINGS. The percentage of a fund's equity assets represented by stocks
or depositary receipts of companies based outside the United States.
- --------------------------------------------------------------------------------
MEDIAN  MARKET  CAP.  An  indicator  of the  size of  companies  in which a fund
invests;  the  midpoint  of  market   capitalization   (market  price  x  shares
outstanding) of a fund's stocks, weighted by the proportion of the fund's assets
invested  in each  stock.  Stocks  representing  half of the fund's  assets have
market capitalizations above the median, and the rest are below it.
- --------------------------------------------------------------------------------
PRICE/BOOK  RATIO.  The share price of a stock divided by its net worth, or book
value,  per share.  For a fund,  the weighted  average  price/book  ratio of the
stocks it holds.
- --------------------------------------------------------------------------------
PRICE/EARNINGS RATIO. The ratio of a stock's current price to its per-share
earnings over the past year. For a fund, the weighted  average P/E of the stocks
it holds. P/E is an indicator of market expectations about corporate  prospects;
the higher the P/E, the greater the  expectations for a company's future growth.
- --------------------------------------------------------------------------------
R-SQUARED.  A measure of how much of a fund's past  returns can be  explained by
the returns from the overall market (or its benchmark  index). If a fund's total
returns  were  precisely  synchronized  with the overall  market's  return,  its
R-squared  would be 1.00.  If the fund's  returns  bore no  relationship  to the
market's returns, its R-squared would be 0.
- --------------------------------------------------------------------------------
RETURN ON  EQUITY.  The annual  average  rate of return  generated  by a company
during the past five years for each dollar of  shareholder's  equity (net income
divided by  shareholder's  equity).  For a fund, the weighted  average return on
equity for the companies whose stocks it holds.
- --------------------------------------------------------------------------------
TURNOVER  RATE. An indication of the fund's  trading  activity.  Funds with high
turnover rates incur higher  transaction costs and are more likely to distribute
capital gains (which are taxable to investors).
- --------------------------------------------------------------------------------

PERFORMANCE SUMMARY                                          AS OF JULY 31, 2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

FINANCIAL STATEMENTS                                   JULY 31, 2003 (UNAUDITED)

STATEMENT OF NET ASSETS

This Statement  provides a detailed list of the fund's holdings,  including each
security's market value on the last day of the reporting period.  Securities are
grouped  and  subtotaled  by asset  type  (common  stocks,  bonds,  etc.) and by
country.  Other assets are added to, and  liabilities  are subtracted  from, the
value of Total  Investments  to calculate  the fund's Net Assets.  Finally,  Net
Assets are divided by the outstanding  shares of the fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.

     At the end of the Statement of Net Assets, you will find a table displaying
the  composition  of the fund's net assets.  Because all income and any realized
gains must be  distributed  to  shareholders  each year,  the bulk of net assets
consists of Paid-in Capital (money invested by shareholders).  The amounts shown
for  Undistributed  Net  Investment  Income and  Accumulated  Net Realized Gains
usually   approximate   the  sums  the  fund  had  available  to  distribute  to
shareholders as income  dividends or capital gains as of the statement date, but
may  differ  because  certain   investments  or  transactions   may  be  treated
differently  for  financial  statement  and tax purposes.  Any  Accumulated  Net
Realized Losses,  and any cumulative excess of distributions  over net income or
net realized gains, will appear as negative  balances.  Unrealized  Appreciation
(Depreciation)  is the  difference  between  the  market  value  of  the  fund's
investments  and their  cost,  and  reflects  the gains  (losses)  that would be
realized if the fund were to sell all of its investments at their statement-date
values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the amount shareholders invested in the
fund,  either by purchasing shares or by reinvesting  distributions,  as well as
the amounts redeemed.  The  corresponding  numbers of Shares Issued and Redeemed
are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders  on a per-share  basis. It also presents the Total Return and shows
net investment  income and expenses as percentages of average net assets.  These
data will help you assess:  the  variability  of the fund's net income and total
returns from year to year; the relative  contributions of net income and capital
gains to the fund's total return; how much it costs to operate the fund; and the
extent to which the fund tends to distribute capital gains. The table also shows
the Portfolio  Turnover Rate, a measure of trading activity.  A turnover rate of
100% means that the average security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Precious Metals Fund is registered under the Investment  Company Act of
1940 as an open-end  investment  company,  or mutual  fund.  The fund invests in
securities  of foreign  issuers,  which may subject it to  investment  risks not
normally associated with investing in securities of United States corporations.

A. The following  significant  accounting policies conform to generally accepted
accounting  principles for U.S. mutual funds. The fund consistently follows such
policies in preparing its financial statements.

     1. Security Valuation:  Securities are valued as of the close of trading on
the New York Stock Exchange  (generally 4:00 p.m. Eastern time) on the valuation
date. Equity securities are valued at the


                                       14


NOTES TO FINANCIAL STATEMENTS continued

latest  quoted  sales prices or official  closing  prices taken from the primary
market  in which  each  security  trades;  such  securities  not  traded  on the
valuation date are valued at the mean of the latest quoted bid and asked prices.
Securities  for which  market  quotations  are not readily  available,  or whose
values  have been  materially  affected  by events  occurring  before the fund's
pricing time but after the close of the securities' primary markets,  are valued
by methods  deemed by the board of trustees to  represent  fair value.  Precious
metals  are  valued  at the mean of the  latest  quoted  bid and  asked  prices.
Temporary  cash  investments  acquired over 60 days to maturity are valued using
the  latest  bid  prices or using  valuations  based on a matrix  system  (which
considers such factors as security  prices,  yields,  maturities,  and ratings),
both  as  furnished  by  independent  pricing  services.  Other  temporary  cash
investments are valued at amortized cost, which approximates market value.
     2.  Foreign   Currency:   Securities  and  other  assets  and   liabilities
denominated  in  foreign  currencies  are  translated  into U.S.  dollars at the
exchange  rates on the  valuation  date as  employed by Morgan  Stanley  Capital
International in the calculation of its indexes.
     Realized  gains  (losses) and  unrealized  appreciation  (depreciation)  on
investment securities include the effects of changes in exchange rates since the
securities  were  purchased,  combined  with the  effects of changes in security
prices. Fluctuations in the value of other assets and liabilities resulting from
changes in exchange  rates are recorded as  unrealized  foreign  currency  gains
(losses) until the asset or liability is settled in cash, when they are recorded
as realized foreign currency gains (losses).
     3.  Repurchase  Agreements:  The fund,  along  with  other  members  of The
Vanguard  Group,  transfers  uninvested  cash balances to a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements  mature.  Each agreement  requires that
the market value of the  collateral be sufficient to cover  payments of interest
and principal; however, in the event of default or bankruptcy by the other party
to  the  agreement,  retention  of  the  collateral  may  be  subject  to  legal
proceedings.
     4.  Federal  Income  Taxes:  The fund  intends to  continue to qualify as a
regulated   investment  company  and  distribute  all  of  its  taxable  income.
Accordingly,  no provision for federal income taxes is required in the financial
statements.
     5.  Distributions:  Distributions  to  shareholders  are  recorded  on  the
ex-dividend date.
     6. Other:  Dividend  income is recorded on the ex-dividend  date.  Security
transactions  are accounted for on the date securities are bought or sold. Costs
used to determine  realized gains (losses) on the sale of investment  securities
are those of the specific  securities  sold.  Fees  assessed on  redemptions  of
capital shares are credited to paid-in capital.

B. M&G Investment Management,  Ltd. provides investment advisory services to the
fund for a fee  calculated at an annual  percentage  rate of average net assets.
For the six months ended July 31, 2003, the investment  advisory fee represented
an effective annual rate of 0.20% of the fund's average net assets.

C. The Vanguard Group  furnishes at cost corporate  management,  administrative,
marketing,  and distribution  services. The costs of such services are allocated
to the fund  under  methods  approved  by the  board of  trustees.  The fund has
committed to provide up to 0.40% of its net assets in capital  contributions  to
Vanguard.  At July 31,  2003,  the fund had  contributed  capital  of $84,000 to
Vanguard (included in Other Assets), representing 0.02% of the fund's net assets
and 0.08% of  Vanguard's  capitalization.  The fund's  trustees and officers are
also directors and officers of Vanguard.

D.  Distributions  are  determined  on a tax  basis  and  may  differ  from  net
investment income and realized capital gains for financial  reporting  purposes.
Differences   may  be  permanent  or  temporary.   Permanent   differences   are
reclassified among capital accounts in the financial statements to reflect their
tax  character.  Temporary  differences  arise  when  certain  items of  income,
expense,  gain,  or loss are  recognized  in  different  periods  for  financial
statement and tax purposes; these differences will


                                       15

NOTES TO FINANCIAL STATEMENTS (continued)

reverse  at some time in the  future.  Differences  in  classification  may also
result  from the  treatment  of  short-term  gains as  ordinary  income  for tax
purposes.

     During the six months  ended July 31, 2003,  the fund  realized net foreign
currency losses of $79,000, which permanently decreased distributable net income
for  tax  purposes;   accordingly,  such  losses  have  been  reclassified  from
accumulated net realized losses to overdistributed net investment income.

     Certain  of the  fund's  investments  are in  securities  considered  to be
"passive foreign  investment  companies," for which any unrealized  appreciation
and/or  realized gains are required to be included in  distributable  net income
for tax purposes.  Unrealized  appreciation  of  $9,407,000  on passive  foreign
investment  company  holdings at January 31, 2003,  has been included in current
and prior years'  distributions  to shareholders and is reflected in the balance
of overdistributed net investment income.

     During 2001, the fund elected to use a provision of the Taxpayer Relief Act
of 1997 to  mark-to-market  certain  appreciated  securities  held on January 1,
2001;  such  securities  were treated as sold and  repurchased,  with unrealized
gains of $46,006,000  becoming  realized,  for tax purposes.  The mark-to-market
created a difference between the cost of investments for financial statement and
tax purposes,  which will reverse when the securities are sold. Through July 31,
2003, the fund realized gains on the sale of these  securities of $1,494,000 for
financial statement  purposes,  which were included in prior year mark-to-market
gains for tax purposes.  The remaining difference of $44,512,000 is reflected in
the balance of accumulated net realized  losses;  the  corresponding  difference
between  the  securities'  cost for  financial  statement  and tax  purposes  is
reflected in unrealized appreciation.

     The fund's  tax-basis  capital gains and losses are determined  only at the
end of each fiscal year.  For tax  purposes,  at January 31, 2003,  the fund had
available  realized  losses of $34,053,000 to offset future net capital gains of
$19,570,000 through January 31, 2007,  $13,355,000 through January 31, 2008, and
$1,128,000  through  January 31, 2010. The fund will use these capital losses to
offset net  taxable  capital  gains,  if any,  realized  during the year  ending
January 31, 2004;  should the fund realize net capital  losses for the year, the
losses will be added to the loss carryforward balances above.

     At July 31, 2003, net unrealized  appreciation of investment securities for
tax purposes was  $54,833,000,  consisting of unrealized gains of $73,876,000 on
securities  that had risen in value  since their  purchase  and  $19,043,000  in
unrealized losses on securities that had fallen in value since their purchase or
since being marked-to-market for tax purposes.

     The fund had net unrealized  foreign  currency losses of $47,000  resulting
from the translation of other assets and liabilities at July 31, 2003.

E. During the six months ended July 31, 2003, the fund purchased  $49,670,000 of
investment  securities and sold $130,534,000 of investment securities other than
temporary cash investments.

F. The market value of  securities on loan to  broker/dealers  at July 31, 2003,
was  $45,267,000,  for which the fund held cash collateral of  $47,247,000.  The
fund invests cash collateral  received in repurchase  agreements,  and records a
liability for the return of the collateral, during the period the securities are
on loan.

THE PEOPLE WHO GOVERN YOUR FUND

The  trustees of your mutual fund are there to see that the fund is operated and
managed in your best interests since, as a shareholder,  you are a part owner of
the fund.  Your  fund  trustees  also  serve on the  board of  directors  of The
Vanguard  Group,  Inc.,  which is owned by the  Vanguard(R)  funds and  provides
services to them on an at-cost basis.

     A majority of Vanguard's board members are  independent,  meaning that they
have no  affiliation  with  Vanguard or the funds they  oversee,  apart from the
investments they have made as private individuals. Our independent board members
bring  distinguished  backgrounds in business,  academia,  and public service to
their task of working  with  Vanguard  officers to  establish  the  policies and
oversee the activities of the funds.

     Among board members' responsibilities are selecting investment advisers for
the  funds;  monitoring  fund  operations,  performance,  and  costs;  reviewing
contracts;  nominating  and  selecting  new  trustees/directors;   and  electing
Vanguard  officers.  The dates in  parentheses  below show when each trustee was

ETERNAL PRINCIPLES

     Markets change,  but the principles of successful  investing do not. During
the past few years, radical upheaval in the stock market has displayed the power
of this simple truth to dramatic effect.
     In the late 1990s,  stocks  experienced one of the greatest bull markets in
financial  history.  Then, in March 2000,  the longest  downturn since the Great
Depression began.
     In both  bull and bear  markets,  however,  the  principles  of  successful
investing  are  identical:  balance,  diversification,  and  attention to costs.
Balance among stock, bond, and money market funds allows you to pursue long-term
growth while moderating your risk.  Diversification  limits your exposure to the
disasters  that can befall any one security or sector.  Attention to costs means
you keep a larger share of any rewards produced by your investments.
     These principles are timeless. In fact, they're the basis of our very first
mutual  fund--Vanguard(R)  Wellington(TM) Fund, a balanced portfolio established
in 1929. Over time, balance, diversification, and attention to costs have proven
to be the master keys to investment success.

Fellow Shareholder,

Stocks in general surged during the six months ended July 31, 2003, and those of
real  estate  investment  trusts were no  exception.  In this  environment,  the
Investor Shares of Vanguard REIT Index Fund posted a remarkable half-year return
of 22.6%,  slightly  lagging the result of its target  index but  outpacing  the
returns of the average real estate mutual fund and the broad market.

appear  in the table on page 4. As of July 31,  the  fund's  dividend  yield was
6.22% for  Investor  Shares and 6.28% for  Admiral  Shares.  (These  figures may
include  some  payments  that  represent  a return of capital by the  underlying
REITs, which is determined by each REIT at the end of its fiscal year.)

INVESTORS' APPREHENSION TURNED TO OPTIMISM
At the start of the REIT Index Fund's fiscal half-year, economic uncertainty and
the impending conflict with Iraq loomed large in the U.S. financial markets.  By
the end of the period,  the mood had changed from apprehension to optimism.  The
successful  military campaign in Iraq, the return of corporate  earnings growth,
and  surprisingly  positive  economic  reports,  including  better-than-expected
growth in U.S. output during the April-June quarter, drove stock prices higher.
     During the full six months, the broad U.S. stock market climbed nearly 19%.

losses  during the past few years,  rebounded  strongly.  The  market's  smaller
stocks outpaced their larger  counterparts  as investors  demonstrated a renewed
appetite for risk. U.S. investors also earned good returns in many international
markets,  though stock  performance was only part of the story. A decline in the
U.S. dollar's relative value transformed  mediocre euro- and British pound-based
results into impressive dollar-denominated returns.

SHORT- AND LONGER-TERM INTEREST RATES WENT THEIR SEPARATE WAYS
By June  13,  continually  rising  bond  prices  had  trimmed  the  yield of the
benchmark  10-year U.S.  Treasury  note to a 45-year low of 3.11%.  In the weeks
that followed,  however, rates rebounded,  and the yield of the 10-year Treasury
note closed the period at 4.41%. For the full six months, rising bond yields and
falling  bond  prices  translated  into a total  return  of 0.3% for the  Lehman
Brothers  Aggregate Bond Index, a measure of the taxable  investment-grade  bond
market.
     Short-term  interest  rates,  which  are more  directly  influenced  by the
Federal Reserve Board,  began the period low and finished lower. In an effort to
add fuel to the economic  expansion,  the Fed trimmed its target for the federal
funds  rate by 25 basis  points  (0.25  percentage  point)  to 1.00% at its June
meeting.  The 3-month U.S. Treasury bill, which typically follows Fed moves with
a lag, began the fiscal half-year at 1.17% and closed the period at 0.94%.


REAL ESTATE INVESTMENTS  POSTED IMPRESSIVE GAINS,  ALTHOUGH THE LODGING INDUSTRY
SLEPT THROUGH THE RALLY
With an economy  seemingly  going in the right  direction and interest  rates so
low,  yield-hungry  investors  boosted  demand and  prices for REITs.  The 22.6%
six-month return of the REIT Index Fund's Investor Shares was

A recovering economy and low interest rates made REITs especially attractive.

4  percentage  points  higher than that of the broad stock  market and  slightly
above that of the average competing fund. As expected, your fund closely tracked
the Target REIT Composite,  which is the fund's target index adjusted for the 2%
cash position that your fund normally holds for liquidity purposes.
     Results were impressive across office, industrial,  retail, and residential
REITs. The fund's three largest  individual  holdings--Equity  Office Properties
Trust, Simon Property Group, and Equity Residential--returned 20%, 34%, and 18%,
respectively.
     In fact,  out of almost  120 stocks in the fund,  only 12 did not  register
double-digit  gains,  and only 2 (both hotel  REITs)  posted  negative  returns.
Although hotel REITs  recovered  somewhat from the travel  industry's  downturn,
they did not completely make up for lost ground.
     Returns from REITs during the past six months--indeed,  over the past three
years--have been  remarkable.  We should not expect future returns to be as high
as the return recorded during the past half-year.  However, relative to actively
managed  real estate funds on the whole,  we believe your fund will  continue to
provide  competitive  results  over  the long  run,  in large  part  because  of
Vanguard's  cost  advantage.  The  REIT  Index  Fund's  Investor  Shares  had an
annualized expense ratio (operating costs as a percentage of average net assets)
during the past half-year of 0.27% ($2.70 per $1,000 of assets), a mere fraction
of the 1.63% ($16.30 per $1,000 of assets) charged by the average peer fund.
- --------------------------------------------------------------------------------
Few  areas  were left out of the  market  surge--90%  of the  stocks in the fund
registered double-digit gains.
- --------------------------------------------------------------------------------
LESSONS FROM THE PAST
Stock  investors were finally  rewarded for their patience  during the prolonged
bear market as equities  rebounded during the past six months--just as investors
who stuck with bonds during the booming  1990s  eventually  were rewarded in the
first years of the new millennium.
     But the investor who maintained a portfolio  diversified  across and within
asset  classes--and who  periodically  rebalanced that portfolio to the original
target  allocation--benefited most, enjoying much of the gains during the period
but with considerably less volatility.
     The past three  years have also shown that  modest  investments  in sectors
that have a  relatively  low  correlation  to the broad market (such as the real
estate sector) can add value by further  diversifying  an already  well-balanced
portfolio.  Nevertheless,  no one can predict with accuracy and  consistency how
the overall financial markets will perform, let alone any one

                                                                            ----

industry.  For that reason,  we believe a balanced  approach--with no outlandish
bets on any one sector,  market  segment,  or asset  class--is  still the wisest
course.

================================================================================
GLOSSARY OF INVESTMENT TERMS

BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation to the ups and downs of the fund's  target  index or an overall  market
index.  Each index is assigned a beta of 1.00.  Compared  with a given index,  a
fund with a beta of 1.20 typically  would have seen its share price rise or fall
by 12% when the index  rose or fell by 10%.  However,  a fund's  beta  should be
reviewed in conjunction with its R-squared (see definition below). The lower the
R-squared, the less correlation there is between the fund and the benchmark, and
the less reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------


CASH  INVESTMENTS.  The  percentage  of a fund's  net assets  invested  in "cash
equivalents"--highly  liquid,  short-term,   interest-bearing  securities.  This
figure does not include cash invested in futures contracts or other equity index
products to simulate stock investment.
- --------------------------------------------------------------------------------

EARNINGS  GROWTH RATE.  The average  annual rate of growth in earnings  over the
past five years for the stocks now in a fund.
- --------------------------------------------------------------------------------

EXPENSE  RATIO.  The  percentage of a fund's  average net assets used to pay its
annual  administrative  and advisory  expenses.  These expenses  directly reduce
returns to investors.
- --------------------------------------------------------------------------------

MEDIAN MARKET CAP. An indicator of the size of companies in which a fund
invests; the midpoint of market capitalization (market price x shares
outstanding) of a fund's stocks, weighted by the proportion of the fund's assets
invested in each stock. Stocks representing half of the fund's assets have
market capitalizations above the median, and the rest are below it.
- --------------------------------------------------------------------------------

PRICE/BOOK  RATIO.  The share price of a stock divided by its net worth, or book
value,  per share.  For a fund,  the weighted  average  price/book  ratio of the
stocks it holds.
- --------------------------------------------------------------------------------

PRICE/EARNINGS  RATIO.  The ratio of a stock's  current  price to its  per-share
earnings over the past year. For a fund, the weighted  average P/E of the stocks
it holds. P/E is an indicator of market expectations about corporate  prospects;
the higher the P/E, the greater the expectations for a company's future growth.
- --------------------------------------------------------------------------------

R-SQUARED.  A measure of how much of a fund's past  returns can be  explained by
the returns from the market in general,  as measured by the fund's  target index
or by an  overall  market  index.  If a  fund's  total  returns  were  precisely
synchronized with an index's returns, its R-squared would be 1.00. If the fund's
returns bore no relationship to the index's returns, its R-squared would be 0.
- --------------------------------------------------------------------------------

RETURN ON  EQUITY.  The annual  average  rate of return  generated  by a company
during the past five years for each dollar of  shareholder's  equity (net income
divided by  shareholder's  equity).  For a fund, the weighted  average return on
equity for the companies whose stocks it holds.
- --------------------------------------------------------------------------------

TURNOVER  RATE. An indication of the fund's  trading  activity.  Funds with high
turnover rates incur higher  transaction costs and are more likely to distribute
capital gains (which are taxable to investors).
- --------------------------------------------------------------------------------

YIELD.   A  snapshot  of  a  fund's  income  from   dividends,   interest,   and
return-of-capital  distributions.  The  index  yield  is  based  on the  current
annualized  rate of  dividends  and  other  distributions  paid on stocks in the
index.

PERFORMANCE SUMMARY                                          As of July 31, 2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

security's  market value on the last day of the  reporting  period.  Real Estate
Investment Trusts are listed in descending  market-value  order.  Temporary cash
investments and other assets are added to, and liabilities are subtracted  from,
the value of Total Real Estate  Investment  Trusts to  calculate  the fund's Net
Assets. Finally, Net Assets are divided by the outstanding shares of the fund to
arrive at its share price, or Net Asset Value (NAV) Per Share.
     At the end of the Statement of Net Assets, you will find a table displaying
the  composition  of the fund's net assets.  Because all income and any realized
gains must be  distributed  to  shareholders  each year,  the bulk of net assets
consists of Paid-in Capital (money invested by shareholders).  The amounts shown
for  Undistributed  Net  Investment  Income and  Accumulated  Net Realized Gains
usually   approximate   the  sums  the  fund  had  available  to  distribute  to
shareholders as income  dividends or capital gains as of the statement date, but
may  differ  because  certain   investments  or  transactions   may  be  treated
differently  for  financial  statement  and tax purposes.  Any  Accumulated  Net
Realized Losses,  and any cumulative excess of distributions  over net income or
net realized gains, will appear as negative  balances.  Unrealized  Appreciation
(Depreciation)  is the  difference  between  the  market  value  of  the  fund's
investments  and their  cost,  and  reflects  the gains  (losses)  that would be
realized if the fund were to sell all of its investments at their statement-date
values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the net amount shareholders invested in
or redeemed  from the fund.  Distributions  and Capital Share  Transactions  are
shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders on a per-share basis for each class of shares. It also presents the
Total  Return and shows net  investment  income and expenses as  percentages  of
average net  assets.  These data will help you assess:  the  variability  of the
fund's  net  income  and  total   returns  from  year  to  year;   the  relative
contributions  of net income and capital gains to the fund's total  return;  how
much it costs to  operate  the fund;  and the  extent to which the fund tends to
distribute  capital gains.  The table also shows the Portfolio  Turnover Rate, a
measure of trading  activity.  A  turnover  rate of 100% means that the  average
security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard REIT Index Fund is registered under the Investment  Company Act of 1940
as an open-end  investment  company, or mutual fund. The fund offers two classes
of shares,  Investor Shares and Admiral Shares. Investor Shares are available to
any investor who meets the fund's minimum purchase requirements.  Admiral Shares
are designed for investors who meet certain administrative,  servicing,  tenure,
and account-size criteria.

A. The following  significant  accounting policies conform to generally accepted
accounting  principles for U.S. mutual funds. The fund consistently follows such
policies in preparing its financial statements.
     1. SECURITY VALUATION:  Securities are valued as of the close of trading on
the New York Stock Exchange  (generally 4:00 p.m. Eastern time) on the valuation
date. Equity securities are valued at the latest quoted sales prices or official
closing prices taken from the primary market in which each security trades; such
securities not traded on the valuation date are valued at the mean of the latest
quoted bid and asked  prices.  Securities  for which market  quotations  are not
readily  available,  or whose  values  have been  materially  affected by events
occurring  before the fund's pricing time but after the close of the securities'
primary  markets,  are  valued by  methods  deemed by the board of  trustees  to
represent  fair  value.  Temporary  cash  investments  acquired  over 60 days to
maturity are valued using the latest bid prices or using  valuations  based on a
matrix  system  (which  considers  such  factors  as

- ----
14


security  prices,  yields,
maturities,  and ratings),  both as furnished by independent  pricing  services.
Other  temporary  cash   investments   are  valued  at  amortized  cost,   which
approximates market value.
     2.  REPURCHASE  AGREEMENTS:  The fund,  along  with  other  members  of The
Vanguard Group,  transfers  uninvested cash balances into a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements  mature.  Each agreement  requires that
the market value of the  collateral be sufficient to cover  payments of interest
and principal; however, in the event of default or bankruptcy by the other party
to  the  agreement,  retention  of  the  collateral  may  be  subject  to  legal
proceedings.
     3.  FEDERAL  INCOME  TAXES:  The fund  intends to  continue to qualify as a
regulated   investment  company  and  distribute  all  of  its  taxable  income.
Accordingly,  no provision for federal income taxes is required in the financial
statements.
     4.  DISTRIBUTIONS:  Distributions  to  shareholders  are  recorded  on  the
ex-dividend date.
     5. OTHER:  Dividend  income is recorded on the ex-dividend  date.  Dividend
income  is  recorded  at  management's   estimate  of  the  income  included  in
distributions  received  from the REIT  investments.  Distributions  received in
excess of this amount are  recorded as a reduction  of the cost of  investments.
The actual  amounts of income and return of capital are  determined by each REIT
only  after its fiscal  year-end,  and may differ  from the  estimated  amounts.
Security  transactions  are accounted for on the date  securities  are bought or
sold. Costs used to determine  realized gains (losses) on the sale of investment
securities  are  those  of  the  specific  securities  sold.  Fees  assessed  on
redemptions of capital shares are credited to paid-in capital.
     Each class of shares has equal  rights as to assets  and  earnings,  except
that each class  separately  bears certain  class-specific  expenses  related to
maintenance of shareholder  accounts  (included in Management and Administrative
expenses) and shareholder  reporting.  Marketing and  distribution  expenses are
allocated  to each class of shares  based on a method  approved  by the board of
trustees.  Income, other  non-class-specific  expenses,  and gains and losses on
investments  are  allocated  to each class of shares  based on its  relative net
assets.

B.  The  Vanguard  Group  furnishes  at  cost  investment  advisory,   corporate
management,  administrative,  marketing, and distribution services. The costs of
such services are  allocated to the fund under methods  approved by the board of
trustees.  The fund has  committed  to  provide up to 0.40% of its net assets in
capital  contributions  to Vanguard.  At July 31, 2003, the fund had contributed
capital of $455,000 to Vanguard  (included in Other Assets),  representing 0.02%
of the  fund's net assets  and 0.45% of  Vanguard's  capitalization.  The fund's
trustees and officers are also directors and officers of Vanguard.

     C.  Distributions  are  determined  on a tax basis and may differ  from net
investment income and realized capital gains for financial  reporting  purposes.
Differences   may  be  permanent  or  temporary.   Permanent   differences   are
reclassified among capital accounts in the financial statements to reflect their
tax  character.  Temporary  differences  arise  when  certain  items of  income,
expense,  gain,  or loss are  recognized  in  different  periods  for  financial
statement and tax purposes;  these  differences will reverse at some time in the
future.  Differences  in  classification  may also result from the  treatment of
short-term gains as ordinary income for tax purposes.
     The fund's return of capital  distributions and tax-basis capital gains and
losses are determined only at the end of each fiscal year. For tax purposes,  at
January 31, 2003,  the fund had  available  realized  losses of  $36,071,000  to
offset future net capital gains of  $31,736,000  through  January 31, 2008,  and
$4,335,000  through  January 31, 2010. The fund will use these capital losses to
offset net  taxable  capital  gains,  if any,  realized  during the year  ending
January 31, 2004;  should the fund realize net capital  losses for the year, the
losses will be added to the loss carryforward balances above.

                                                                            ----
                                                                              15

Notes to Financial Statements (continued)

     At July 31, 2003, net unrealized  appreciation of investment securities for
tax purposes was $404,952,000, consisting of unrealized gains of $463,385,000 on
securities  that had risen in value  since their  purchase  and  $58,433,000  in
unrealized losses on securities that had fallen in value since their purchase.

D. During the six months ended July 31, 2003, the fund purchased $457,506,000 of
investment  securities and sold $52,120,000 of investment  securities other than
temporary cash investments.

E. The market value of  securities on loan to  broker/dealers  at July 31, 2003,
was  $32,506,000,  for which the fund held cash collateral of  $34,062,000.  The
fund invests cash collateral  received in repurchase  agreements,  and records a
liability for the return of the collateral, during the period the securities are
on loan.

F. Capital share transactions for each class of shares were:

THE PEOPLE WHO GOVERN YOUR FUND

The  trustees of your mutual fund are there to see that the fund is operated and
managed in your best interests since, as a shareholder,  you are a part owner of
the fund.  Your  fund  trustees  also  serve on the  board of  directors  of The
Vanguard  Group,  Inc.,  which is owned by the  Vanguard(R)  funds and  provides
services to them on an at-cost basis.

     A majority of Vanguard's board members are  independent,  meaning that they
have no  affiliation  with  Vanguard or the funds they  oversee,  apart from the
investments they have made as private individuals. Our independent board members
bring  distinguished  backgrounds in business,  academia,  and public service to
their task of working  with  Vanguard  officers to  establish  the  policies and
oversee the activities of the funds.

     Among board members' responsibilities are selecting investment advisers for
the  funds;  monitoring  fund  operations,  performance,  and  costs;  reviewing
contracts;  nominating  and  selecting  new  trustees/directors;   and  electing
Vanguard  officers.  The dates in  parentheses  below show when each trustee was
initially elected.

Vanguard(R) Health Care Fund

SEMIANNUAL REPORT

Eternal Principles

     Markets change,  but the principles of successful  investing do not. During
the past few years, radical upheaval in the stock market has displayed the power
of this simple truth to dramatic effect.
     In the late 1990s,  stocks  experienced one of the greatest bull markets in
financial  history.  Then, in March 2000,  the longest  downturn since the Great
Depression began.
     In both  bull and bear  markets,  however,  the  principles  of  successful
investing  are  identical:  balance,  diversification,  and  attention to costs.
Balance among stock, bond, and money market funds allows you to pursue long-term
growth while moderating your risk.  Diversification  limits your exposure to the
disasters  that can befall any one security or sector.  Attention to costs means
you keep a larger share of any rewards produced by your investments.
     These principles are timeless. In fact, they're the basis of our very first
mutual  fund--Vanguard(R)  Wellington(TM) Fund, a balanced portfolio established
in 1929. Over time, balance, diversification, and attention to costs have proven
to be the master keys to investment success.

Summary
*    Vanguard  Health Care Fund returned  15.5% during the six months ended July
     31, 2003.
*    The fund's performance was significantly  better than that of its benchmark
     index  (+10.1%),  but fell well short of the returns  for its average  peer
     (+23.7%) and the broad U.S. stock market (+18.6%).
*    Solid   performances   from  the  fund's  holdings  in  biotechnology   and
     pharmaceutical companies bolstered returns.

Fellow Shareholder,
During the first half of fiscal 2004, Vanguard Health Care Fund recorded a total
return of 15.5%,  a strong  absolute  result that  reflected the  post-Iraqi-war
surge in the stock market. The fund's performance outpaced that of its unmanaged
benchmark  but  lagged  the  results  of its  average  mutual  fund peer and the
broad-based  Wilshire  5000 Total  Market  Index.
     The table  below  presents  the  six-month  returns  (capital  change  plus
reinvested  distributions) for the fund's two share classes,  as well as for its
comparative  standards.  Details  on changes  in net asset  value and  per-share
distributions can be found in the table on page 4.

Investors' Apprehension Turned to Optimism
At the start of the fiscal  half-year,  economic  uncertainty  and the impending
conflict with Iraq loomed large in the U.S. financial markets. By the end of the
period,  the mood had changed  from  apprehension  to optimism.  The  successful
military  campaign  in Iraq,  the  return  of  corporate  earnings  growth,  and
surprisingly positive economic reports--including better-than-expected growth in
U.S. output during the April-June quarter--drove stock prices higher.
     As the  Wilshire  5000  Index  climbed  toward  its  gain  of  nearly  19%,
technology  stocks and other  growth-oriented  issues,  which had  sustained big
losses  during the past few years,  rebounded  strongly.  The  market's  smaller
stocks outpaced their larger  counterparts  as investors  demonstrated a renewed
appetite for risk.
     U.S.  investors  also earned good  returns in many  international  markets,
though  stock  performance  was only part of the  story.  A decline  in the U.S.
dollar's  relative  value  transformed  mediocre  euro- and British  pound-based
results into impressive dollar-denominated returns.

Short- and Longer-Term Interest Rates Went Their Separate Ways
By June  13,  continually  rising  bond  prices  had  trimmed  the  yield of the
benchmark  10-year

U.S.  Treasury  note to a 45-year  low of 3.11%.  In the  weeks  that  followed,
however, rates rebounded,  and the yield of the 10-year Treasury note closed the
period at 4.41%.  For the full six months,  rising bond yields and falling  bond
prices translated into a total return of 0.3% for the Lehman Brothers  Aggregate
Bond Index, a measure of the taxable investment-grade bond market.

*Annualized.


     Short-term  interest  rates,  which  are more  directly  influenced  by the
Federal Reserve Board,  began the period low and finished lower. In an effort to
add fuel to the economic  expansion,  the Fed trimmed its target for the federal
funds  rate by 25 basis  points  (0.25  percentage  point)  to 1.00% at its June
meeting.  The 3-month U.S. Treasury bill, which typically follows Fed moves with
a lag, began the fiscal half-year at 1.17% and closed the period at 0.94%.

A Period of Robust Gains for Your Fund
The Health Care Fund's result  during this period  marked a welcome  change from
its disappointing 2003 fiscal year.  Although the fund's six-month gain exceeded
that of its benchmark index by a solid margin, its somewhat less-aggressive risk
profile led it to a return well behind that of its average peer.
     We underperformed  the average  competitor  primarily because of the fund's
smaller exposure to biotechnology  stocks.  When the health care industry's more
speculative  stocks,  such as biotech issues, are dominating returns as they did
during the past six  months,  your fund  stands to lag its peers,  many of which
hold  larger  weightings  in  these  volatile  stocks.   When  these  subsectors
experience difficulties,  however, the fund's broad diversification works to its
advantage,  a characteristic that has helped to keep your fund ahead of the pack
over the long haul.
     The Health Care Fund's pharmaceutical  holdings had particularly impressive
gains,  with both foreign and domestic  drugmakers  (which together  represented
some  two-thirds  of fund  assets on average)  showing  renewed  vigor.  Several
companies,  such as AstraZeneca and Wyeth, saw their stock prices driven notably
higher by improving earnings and progress in clinical drug trials.

     Your fund's adviser,  Wellington Management Company, has consistently shown
its commitment to achieving  competitive  returns through broad  diversification
across the health care industry and through its search for  attractively  valued
stocks poised for earnings growth. Low costs are another important  component of
the fund's quest to provide  competitive  returns.  A fund's operating  expenses
reduce the  return  that ends up in  shareholders'  pockets  dollar for  dollar.
During the period,  your fund's  Investor  Shares carried an annualized  expense
ratio (operating costs as a percentage of average net assets) of 0.30%, or $3.00
per $1,000 invested. This is far below the 1.84%, or $18.40 per $1,000 invested,
charged by the average health/biotechnology fund. The fund's Admiral Shares have
an even lower expense ratio of 0.22%.

Resist the Temptation to Change Your Long-Term Plan
The stock  market  looked more  enticing in the past few months than it had in a
long time.  But does that mean we should  expect even better  things to come? Is
now the  "right"  time to get  aggressive  and put more  assets  into the  stock
market?
     The truth is that  nobody,  not even the most skilled  market-watcher,  can
answer those questions.  Nobody knows what the future holds for any asset class.
That's why  Vanguard  has always  advocated  a  balanced,  long-term  investment
approach:  holding  a mix of  stock,  bond,  and  money  market  funds  that  is
appropriate for your unique goals, financial circumstances,  and risk tolerance.
As one part of a carefully planned,  well-diversified  stock portfolio, a mutual
fund  that  focuses  on a  particular  industry--as  Vanguard  Health  Care Fund
does--may be useful to investors who are comfortable with the added risks. Thank
you for your continued confidence in Vanguard.


Sincerely,
John J. Brennan
Chairman and Chief Executive Officer

Report from the Adviser

Vanguard Health Care Fund returned 15.5% for the fiscal half-year ended July 31,
2003.  This  result was better  than the 10.1%  return of the  Standard & Poor's
Health   Sector   Index   but   trailed   the  23.7%   return  of  the   average
health/biotechnology  fund.

The  Investment  Environment
As is common when the economy  begins to show signs of recovery,  the market was
led by  smaller-capitalization  stocks.  Within the  health  care  sector,  that
leadership was manifested in a very strong biotechnology subsector, which gained
roughly 50% during the half-year.  Stocks of medical products companies and most
categories of the health services group were stronger than the overall market.

Our Successes
The  four  largest  contributors  to the  fund's  performance--Gilead  Sciences,
Genentech,  Amgen,  and  Genzyme--were  from the  very  strong  biotech  sector.
Managed-care  companies  Aetna,  Humana,  and  Coventry  Health  Care  were also
standout  performers.  Our Shortfalls The weakest area for the fund in the first
half of its  fiscal  year was its  Japanese  stock  holdings.  We added to these
positions  near the end of the period,  believing  the  weakness  had created an
excellent  opportunity.  Hospital stocks were the other weak group for us during
the period.

The Fund's Positioning
We benefited  during the half-year from having increased our biotech position in
the  previous  fiscal  year.  However,  we  will  always  seek  to  provide  our
shareholders  with a  well-diversified  health care fund that offers more stable
returns than the smaller,  biotech-oriented funds that make up a good proportion
of the  health/biotechnology  category.  We strive to buy into weakness and sell
into  strength,  a strategy  that has  recently  led us to  increase  the fund's
international  exposure  and reduce its biotech  exposure.  We believe  that the
international sector is particularly attractive,  and the fund

- --------------------------------------------------------------------------------
Investment Philosophy

The fund reflects the belief that  investors  who seek to emphasize  health care
stocks as part of a long-term,  balanced  investment  program are best served by
holding a portfolio of securities well diversified across the sector.

Glossary of Investment Terms

Beta. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation  to the ups and downs of the  overall  market  (or  appropriate  market
index).  The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20  typically  would have seen its share price rise or fall by 12% when the
overall market rose or fell by 10%. However, a fund's beta should be reviewed in
conjunction with its R-squared (see definition  below). The lower the R-squared,
the less correlation  there is between the fund and the benchmark,  and the less
reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
Cash  Investments.  The  percentage  of a fund's  net assets  invested  in "cash
equivalents"--highly  liquid,  short-term,   interest-bearing  securities.  This
figure does not include cash invested in futures contracts or other equity index
products to simulate stock investment.
- --------------------------------------------------------------------------------
Earnings  Growth Rate.  The average  annual rate of growth in earnings  over the
past five years for the stocks now in a fund.
- --------------------------------------------------------------------------------
Expense  Ratio.  The  percentage of a fund's  average net assets used to pay its
annual  administrative  and advisory  expenses.  These expenses  directly reduce
returns to investors.
- --------------------------------------------------------------------------------
Foreign Holdings. The percentage of a fund's equity assets represented by stocks
or American Depositary Receipts of companies based outside the United States.
- --------------------------------------------------------------------------------
Median  Market  Cap.  An  indicator  of the  size of  companies  in which a fund
invests;  the  midpoint  of  market   capitalization   (market  price  x  shares
outstanding) of a fund's stocks, weighted by the proportion of the fund's assets
invested  in each  stock.  Stocks  representing  half of the fund's  assets have
market capitalizations above the median, and the rest are below it.
- --------------------------------------------------------------------------------
Price/Book  Ratio.  The share price of a stock divided by its net worth, or book
value,  per share.  For a fund,  the weighted  average  price/book  ratio of the
stocks it holds.
- --------------------------------------------------------------------------------
Price/Earnings  Ratio.  The ratio of a stock's  current  price to its  per-share
earnings over the past year. For a fund, the weighted  average P/E of the stocks
it holds. P/E is an indicator of market expectations about corporate  prospects;
the higher the P/E, the greater the expectations for a company's future growth.
- --------------------------------------------------------------------------------
R-Squared.  A measure of how much of a fund's past  returns can be  explained by
the returns from the overall market (or its benchmark  index). If a fund's total
returns  were  precisely  synchronized  with the overall  market's  return,  its
R-squared  would be 1.00.  If the fund's  returns  bore no  relationship  to the
market's returns, its R-squared would be 0.
- --------------------------------------------------------------------------------
Return on  Equity.  The annual  average  rate of return  generated  by a company
during the past five years for each dollar of  shareholder's  equity (net income
divided by  shareholder's  equity).  For a fund, the weighted  average return on
equity for the companies whose stocks it holds.
- --------------------------------------------------------------------------------
Turnover  Rate. An indication of the fund's  trading  activity.  Funds with high
turnover rates incur higher  transaction costs and are more likely to distribute
capital gains (which are taxable to investors).
- --------------------------------------------------------------------------------
Yield.  A snapshot of a fund's  income from interest and  dividends.  The yield,
expressed  as a  percentage  of the fund's net asset  value,  is based on income
earned over the past 30 days and is  annualized,  or  projected  forward for the
coming  year.  The  index  yield  is  based on the  current  annualized  rate of
dividends paid on stocks in the index.

Performance Summary                                          As of July 31, 2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

Statement of Net Assets

This Statement  provides a detailed list of the fund's holdings,  including each
security's market value on the last day of the reporting period.  Securities are
grouped and subtotaled by asset type (common stocks,  bonds, etc.) and by sector
within the fund's designated industry; international securities, if significant,
may be presented in a separate group. Other assets are added to, and liabilities
are subtracted from, the value of Total  Investments to calculate the fund's Net
Assets. Finally, Net Assets are divided by the outstanding shares of the fund to
arrive at its share price, or Net Asset Value (NAV) Per Share.
     At the end of the Statement of Net Assets, you will find a table displaying
the  composition  of the fund's net assets.  Because all income and any realized
gains must be  distributed  to  shareholders  each year,  the bulk of net assets
consists of Paid-in Capital (money invested by shareholders).  The amounts shown
for  Undistributed  Net  Investment  Income and  Accumulated  Net Realized Gains
usually   approximate   the  sums  the  fund  had  available  to  distribute  to
shareholders as income  dividends or capital gains as of the statement date, but
may  differ  because  certain   investments  or  transactions   may  be  treated
differently  for  financial  statement  and tax purposes.  Any  Accumulated  Net
Realized Losses,  and any cumulative excess of distributions  over net income or
net realized gains, will appear as negative  balances.  Unrealized  Appreciation
(Depreciation)  is the  difference  between  the  market  value  of  the  fund's
investments  and their  cost,  and  reflects  the gains  (losses)  that would be
realized if the fund were to sell all of its investments at their statement-date
values.

Statement of Operations

This Statement shows the types of income earned by the fund during the reporting
period,  and details the operating expenses charged to each class of its shares.
These expenses  directly reduce the amount of investment income available to pay
to  shareholders  as income  dividends.  This  Statement also shows any Net Gain
(Loss) realized on the sale of investments,  and the increase or decrease in the
Unrealized Appreciation (Depreciation) of investments during the period.

Statement of Changes in Net Assets

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the net amount shareholders invested in
or redeemed  from the fund.  Distributions  and Capital Share  Transactions  are
shown separately for each class of shares.

Financial Highlights

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders on a per-share basis for each class of shares. It also presents the
Total  Return and shows net  investment  income and expenses as  percentages  of
average net  assets.  These data will help you assess:  the  variability  of the
fund's  net  income  and  total   returns  from  year  to  year;   the  relative
contributions  of net income and capital gains to the fund's total  return;  how
much it costs to  operate  the fund;  and the  extent to which the fund tends to
distribute  capital gains.  The table also shows the Portfolio  Turnover Rate, a
measure of trading  activity.  A  turnover  rate of 100% means that the  average
security is held in the fund for one year.

Notes to Financial Statements

Vanguard Health Care Fund is registered under the Investment Company Act of 1940
as an  open-end  investment  company,  or mutual  fund.  The fund may  invest in
securities  of foreign  issuers,  which may subject it to  investment  risks not
normally associated with investing in securities of United States  corporations.
The fund  offers two  classes of shares,  Investor  Shares and  Admiral  Shares.
Investor  Shares are  available  to any  investor  who meets the fund's  minimum
purchase  requirements.  Admiral  Shares are  designed  for  investors  who meet
certain administrative, servicing, tenure, and account- size criteria.

A. The following  significant  accounting policies conform to generally accepted
accounting  principles for U.S. mutual funds. The fund consistently follows such
policies in preparing its financial statements.
     1. Security Valuation:  Securities are valued as of the close of trading on
the New York Stock Exchange  (generally 4:00 p.m. Eastern time) on the valuation
date. Equity securities are valued at the latest quoted sales prices or official
closing prices taken from the primary market in which each security trades; such
securities not traded on the valuation date are valued at the mean of the latest
quoted bid and asked  prices.  Securities  for which market  quotations  are not
readily  available,  or whose  values  have been  materially  affected by events
occurring  before the fund's pricing time but after the close of the securities'
primary  markets,  are  valued by  methods  deemed by the board of  trustees  to
represent  fair  value.  Temporary  cash  investments  acquired  over 60 days to
maturity are valued using the latest bid prices or using  valuations  based on a
matrix  system  (which  considers  such  factors  as  security  prices,  yields,
maturities,  and ratings),  both as furnished by independent  pricing  services.
Other  temporary  cash   investments   are  valued  at  amortized  cost,   which
approximates market value.
     2.  Foreign   Currency:   Securities  and  other  assets  and   liabilities
denominated  in  foreign  currencies  are  translated  into U.S.  dollars at the
exchange  rates on the  valuation  date as  employed by Morgan  Stanley  Capital
International in the calculation of its indexes.
     Realized  gains  (losses) and  unrealized  appreciation  (depreciation)  on
investment securities include the effects of changes in exchange rates since the
securities  were  purchased,  combined  with the  effects of changes in security
prices. Fluctuations in the value of other assets and liabilities resulting from
changes in exchange  rates are recorded as  unrealized  foreign  currency  gains
(losses) until the asset or liability is settled in cash, when they are recorded
as realized foreign currency gains (losses).
     3.  Repurchase  Agreements:  The fund,  along  with  other  members  of The
Vanguard  Group,  transfers  uninvested  cash balances to a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  The  fund  may  also  invest  directly  in  repurchase  agreements.
Securities  pledged  as  collateral  for  repurchase  agreements  are  held by a
custodian bank until the  agreements  mature.  Each agreement  requires that the
market value of the  collateral be sufficient to cover  payments of interest and
principal;  however, in the event of default or bankruptcy by the other party to
the agreement, retention of the collateral may be subject to legal proceedings.
     4.  Federal  Income  Taxes:  The fund  intends to  continue to qualify as a
regulated   investment  company  and  distribute  all  of  its  taxable  income.
Accordingly,  no provision for federal income taxes is required in the financial
statements.
     5.  Distributions:  Distributions  to  shareholders  are  recorded  on  the
ex-dividend date.
     6. Other:  Dividend  income is recorded on the ex-dividend  date.  Security
transactions  are accounted for on the date securities are bought or sold. Costs
used to determine  realized gains (losses) on the sale of investment  securities
are those of the specific  securities  sold.  Fees  assessed on  redemptions  of
capital shares are credited to paid-in capital.
     Each class of shares has equal  rights as to assets  and  earnings,  except
that each class  separately  bears certain  class-specific  expenses  related to
maintenance of shareholder  accounts  (included in Management and Administrative
expenses) and shareholder  reporting.  Marketing and  distribution

18


expenses are allocated to each class of shares based on a method approved by the
board of trustees.  Income,  other  non-class-specific  expenses,  and gains and
losses  on  investments  are  allocated  to each  class of  shares  based on its
relative net assets.

B. Wellington  Management Company, llp, provides investment advisory services to
the fund for a fee  calculated  at an  annual  percentage  rate of  average  net
assets.  For the six months ended July 31,  2003,  the  investment  advisory fee
represented an effective annual rate of 0.06% of the fund's average net assets.

C. The Vanguard Group  furnishes at cost corporate  management,  administrative,
marketing,  and distribution  services. The costs of such services are allocated
to the fund  under  methods  approved  by the  board of  trustees.  The fund has
committed to provide up to 0.40% of its net assets in capital  contributions  to
Vanguard.  At July 31, 2003, the fund had  contributed  capital of $3,019,000 to
Vanguard (included in Other Assets), representing 0.02% of the fund's net assets
and 3.02% of  Vanguard's  capitalization.  The fund's  trustees and officers are
also directors and officers of Vanguard.

D. The fund has asked its investment  adviser to direct certain security trades,
subject to obtaining the best price and execution, to brokers who have agreed to
rebate to the fund part of the  commissions  generated.  Such  rebates  are used
solely to reduce the fund's management and administrative  expenses.  The fund's
custodian  bank has also agreed to reduce its fees when the fund  maintains cash
on deposit in the non-interest-bearing custody account. For the six months ended
July 31, 2003, directed brokerage and custodian fee offset arrangements  reduced
expenses  by $745,000  and $8,000,  respectively.  The total  expense  reduction
represented an effective annual rate of 0.01% of the fund's average net assets.

E.  Distributions  are  determined  on a tax  basis  and  may  differ  from  net
investment income and realized capital gains for financial  reporting  purposes.
Differences   may  be  permanent  or  temporary.   Permanent   differences   are
reclassified among capital accounts in the financial statements to reflect their
tax  character.  Temporary  differences  arise  when  certain  items of  income,
expense,  gain,  or loss are  recognized  in  different  periods  for  financial
statement and tax purposes;  these  differences will reverse at some time in the
future.  Differences  in  classification  may also result from the  treatment of
short-term  gains as  ordinary  income for tax  purposes.  The fund's  tax-basis
capital gains and losses are determined only at the end of each fiscal year.
     During the six months  ended July 31, 2003,  the fund  realized net foreign
currency gains of $796,000,  which  increased  distributable  net income for tax
purposes;  accordingly  such gains have been  reclassified  from accumulated net
realized gains to undistributed net investment income.
     At July 31, 2003, net unrealized  appreciation of investment securities for
tax  purposes   was   $4,150,089,000,   consisting   of   unrealized   gains  of
$4,695,386,000  on securities  that had risen in value since their  purchase and
$545,297,000  in unrealized  losses on securities that had fallen in value since
their purchase.
     The fund had net unrealized  foreign  currency  gains of $16,000  resulting
from the translation of other assets and liabilities at July 31, 2003.

F. During the six months ended July 31, 2003, the fund purchased  $1,479,315,000
of investment  securities and sold $1,164,367,000 of investment securities other
than temporary cash investments.

G. The market value of  securities on loan to  broker/dealers  at July 31, 2003,
was  $90,213,000,  for which the fund held cash collateral of  $91,972,000.  The
fund invests cash collateral  received in repurchase  agreements,  and records a
liability for the return of the collateral, during the period the securities are
on loan.

The People Who Govern Your Fund

The  trustees of your mutual fund are there to see that the fund is operated and
managed in your best interests since, as a shareholder,  you are a part owner of
the fund.  Your  fund  trustees  also  serve on the  board of  directors  of The
Vanguard  Group,  Inc.,  which is owned by the  Vanguard(R)  funds and  provides
services to them on an at-cost basis.
     A majority of Vanguard's board members are  independent,  meaning that they
have no  affiliation  with  Vanguard or the funds they  oversee,  apart from the
investments they have made as private individuals. Our independent board members
bring  distinguished  backgrounds in business,  academia,  and public service to
their task of working  with  Vanguard  officers to  establish  the  policies and
oversee the activities of the funds.
     Among board members' responsibilities are selecting investment advisers for
the  funds;  monitoring  fund  operations,  performance,  and  costs;  reviewing
contracts;  nominating  and  selecting  new  trustees/directors;   and  electing
Vanguard  officers.  The dates in  parentheses  below show when each trustee was
initially elected.
