               NOVAVAX, INC. ANNOUNCES 2003 THIRD QUARTER RESULTS
    HIGHLIGHTS INCLUDE FDA APPROVAL OF ESTRASORB(TM), IMPROVED PRODUCT SALES
                           AND LOWER CASH UTILIZATION

COLUMBIA, MD, NOVEMBER 10, 2003 - NOVAVAX, INC. (NASDAQ: NVAX) today announced
financial results for the third quarter ended September 30, 2003.

Total revenues for the third quarter of 2003 were $4.3 million compared to third
quarter 2002 revenues of $2.3 million. Revenues for the third quarter included
$3.6 million of product sales compared to $1.8 million of product sales in the
prior year period, a 100% increase. Product sales increased across all of the
Company's product lines. In particular, sales benefited from the introduction of
the Company's two new prenatal vitamin products, as well as increased orders for
AVC Cream, Nestabs and Gynodiol. Revenue from research and development contracts
with the National Institutes of Health (NIH) and other government agencies
increased 36.5% to $560,000 in the quarter from $410,000 in the third quarter of
2002. In addition to improved quarterly revenues, the Company announced the most
significant event in its history, the FDA approval of ESTRASORB, its proprietary
topical emulsion for estrogen therapy.

For the nine months ended September 30, 2003, total revenues were $7.7 million
compared to total revenues of $12.5 million for the prior year period, a decline
of $4.8 million. Product sales were $6.5 million in the period, a decline of
$4.3 million. A decline in prenatal vitamin revenues year-over-year was due to
the effects of competitive pressure from generics, aggressive sales promotions
in the first half of 2002 and a higher than average volume of expired product
returns as a result of those promotions. An AVC product line decline was also
the result of sales promotions in 2002. Revenues year-to-date also included $1.0
million from research and development contracts and $212,000 in milestone and
licensing fees.

Operating expenses for the three months ended September 30, 2003 were $7.2
million, a decrease of $1.6 million, or 18%, from $8.8 million in the 2002
period. Selling and marketing costs were $2.0 million compared to $2.7 million
incurred for the same period in 2002, a decrease of 26%. The $700,000
year-over-year decline resulted from cost-cutting initiatives. General and
administrative expenses in the quarter were $1.9 million compared to $1.6
million for the third quarter of 2002, an increase of 17%. This increase is due
to lower than usual quarterly general and administrative costs in the third
quarter of 2002, rather than increases in 2003. Research and development
expenses were $2.6 million in the third quarter of 2003 compared to $3.7 million
in the prior year period, a decrease of 30%. This decrease was due to reductions
in clinical trial and NDA filing costs for ESTRASORB when compared to the prior
year period.

Operating expenses for the first nine months ended September 30, 2003 were $20.7
million, a decrease of $9.2 million, or 31%, from $30.0 million in the 2002
period resulting from the Company's planned reduction in spending and its
preservation of capital in conjunction with the delayed approval of ESTRASORB.
Selling and marketing expenses were $6.1 million compared to $10.6 million for
the prior year period, a decrease of 43%. General and administrative expenses in
the period were $5.6 million versus $6.7 million for the comparable period of
2002, a decrease of 16%. Research and development expenses were $7.7 million
compared to $9.8 million in the prior year period, a decrease of $2.1 million,
or 21%.

The net loss for the third quarter of 2003 was $3.4 million, or $0.11 per share,
compared to a net loss of $6.9 million, or $0.28 per share, for the third
quarter of 2002. The decrease in the net loss was primarily related to the
reduction in operating expenses as well as the increase in revenue. Average
shares outstanding for the quarter was 30.1 million compared to 24.7 million in
2002, primarily due to the February 2003 private placement of 4.75 million
shares. The net loss for the first nine months of 2003 was $14.2 million, or
$0.49 per share, compared to a net loss of $18.4 million, or $0.75 per share for
the prior year period.

Nelson M. Sims, President and Chief Executive Officer of Novavax, stated, "This
has been an exciting quarter for Novavax. Most important was the recent FDA
approval of ESTRASORB, which marked the culmination of nine years of work on our
proprietary micellar nanoparticle (MNP) drug delivery platform. With the launch
slated for late in the first quarter of 2004, we are working hard to make sure
everything from sales and marketing to manufacturing to financing is in place.
An important step was the recent addition of Ford Lynch as Senior Vice President
of Sales and Marketing and Howard Miller as Vice President of U.S. Sales to our
sales and marketing team. We are delighted with the development of our
management team and we are optimistic about our ability to successfully launch
ESTRASORB, the first product in our proprietary MNP drug delivery platform.

"We were also pleased with our financial performance in the quarter. As
expected, the launch of our two new prenatal vitamin products, NovaStart and
NovaNatal, in addition to the reduced impact from prior product promotions
resulted in sales improvement across all our product lines in the quarter.

"On the vaccine development front, Novavax continues to receive confirmation of
the value of its technologies. During the quarter we were awarded a $19 million
contract from the National Institute of Allergy and Infectious Diseases for the
design and development of a new class of HIV vaccine candidates for preclinical
and clinical studies. We were also named as part of a consortium led by the
University of Alabama at Birmingham for another HIV grant. This makes two awards
in two months for our HIV vaccine development program and represents a
significant accomplishment for our virus-like particle (VLP) platform
technology."

Mr. Sims concluded, "Since joining Novavax in August, I continue to be impressed
by our progress utilizing our micellar nanoparticle technology. We are convinced
that over the longer-term the platform can be utilized in a vast array of
pharmaceutical applications. In the short term, our focus will be on ESTRASORB.
We have been working diligently with our marketing partner King, who shares our
excitement on the upcoming launch. We are fine-tuning market research,
finalizing our marketing programs and preparing our joint sales forces. I
believe we have all the elements in place for a successful launch of ESTRASORB.
I look forward to updating you on our progress."
