Exhibit 99.1

                     VaxGen Reports Final Financial Results
                           for Fourth Quarter and 2003

      BRISBANE, Calif. - March 30, 2004 - VaxGen, Inc. (Nasdaq: VXGN) today
announced substantial increases in revenues and significantly lower losses for
the fourth quarter and year ended December 31, 2003. The revenue results, which
were filed today in a Form 10-K with the U.S. Securities and Exchange
Commission, are virtually identical to preliminary revenues that VaxGen reported
on February 17, 2004.

      Fourth Quarter Results

      VaxGen recognized revenues for the fourth quarter ended December 31, 2003
of $4.6 million, compared to $1.2 million in the same period a year ago. The net
loss applicable to common stockholders for the quarter ended December 31, 2003
was $8.8 million, or $0.41 per share, compared with a net loss applicable to
common stockholders of $25.9 million, or $1.71 per share, in the fourth quarter
of 2002.

      2003 Results

      For the year ended December 31, 2003, VaxGen recognized $14.3 million in
revenues, an 804% increase compared to revenues of $1.6 million in 2002. The net
loss applicable to common stockholders for the year ended December 31, 2003 was
$28.7 million, or $1.52 per share, compared with a net loss applicable to common
stockholders of $49.8 million, or $3.42 per share, in 2002.

      More than half of the increase in revenues for the year was associated
with contract revenue from the National Institute of Allergy and Infectious
Diseases (NIAID) for the development of VaxGen's recombinant anthrax vaccine
candidate. Of the $14.3 million recognized as revenue in 2003, $8.8 million came
from the first of two anthrax vaccine contracts that VaxGen has received from
NIAID.

      Cash Position and Liquidity

      VaxGen ended the year with $28.7 million in cash and investment securities
and approximately $5.0 million in accounts receivable, which consists primarily
of outstanding invoices associated with its various contracts with NIAID and
other U.S. government agencies. VaxGen's year-end cash and investment securities
balance includes proceeds from the equity financing that the company completed
in December 2003.

      Third-Quarter Restatement

      In the Form 10-K filed today, VaxGen restated its previously reported
results for the three months ended September 30, 2003. Property and Equipment
decreased by $856,000 and operating expenses increased by the same amount. As a
result, the net loss applicable to common stockholders increased by
approximately $469,000, net of minority interest, or $0.03 per share. The
restatement is the result of an adjustment to reduce the capitalization of
internal labor costs and associated overhead.
