Title: Vical Reports Third Quarter 2006 Financial Results

Date: 11/2/2006 6:30:00 AM

    SAN DIEGO, Nov. 2 /PRNewswire-FirstCall/ -- Vical Incorporated
(Nasdaq: VICL) today reported financial results for the quarter ended
September 30, 2006.  Revenues for the third quarter of 2006 were $0.6 million
compared with $2.7 million for the same period of 2005.  The net loss for the
third quarter of 2006 was $7.5 million or $0.24 per share, compared with
$6.1 million or $0.26 per share for the third quarter of 2005.

    Financial results were consistent with the company's guidance of a
projected adjusted net loss for the full year 2006 of between $22 million and
$26 million.  This adjusted net loss excludes non-cash, stock-based
compensation expense and, as a result, is not calculated in accordance with
U.S. generally accepted accounting principles (GAAP).  See "Use of Non-GAAP
Financial Measure" below.  Vical had cash and investments of approximately
$70 million at September 30, 2006, including the net proceeds of $9.7 million
from a registered direct offering in August 2006, in which the company sold
approximately 2.1 million shares of its common stock to a single institutional
investor.  Vical completed two additional registered direct offerings in
October 2006, selling approximately 7.5 million shares of its common stock to
institutional investors for estimated net proceeds of $37.4 million.


    Recent Highlights

    *  In the most recent offering, Temasek Holdings (Private) Ltd. purchased
       approximately 5.0 million shares of Vical's common stock for
       $25.0 million, making it the company's largest shareholder.  Temasek
       manages a diversified U.S.$80 billion portfolio for the Singapore
       government, and has generated total shareholder returns of
       18% compounded annually since its inception in 1974.

       Temasek conducted extensive research over a period of months to
       evaluate Vical's technology, intellectual property, development
       programs, management, and financial position before making the decision
       to invest.  A major area of focus in Temasek's investigation was
       Vical's program to develop a DNA vaccine to protect humans against
       emerging strains of influenza virus that have the potential to cause a
       pandemic.  Proceeds from the offering will support Phase 1 human
       clinical testing of the vaccine expected to begin in 2007.

    *  At the Influenza Vaccines for the World Conference in October, the
       company announced that a single injection of its avian influenza DNA
       vaccine candidate provided 100% protection in ferrets against lethal
       challenge with a highly virulent H5N1 virus (Vietnam/1203/2004).
       Conventional vaccines under development for avian flu typically have
       required two or more doses in humans, even with novel adjuvants, to
       produce the immunogenicity levels expected to provide protection.

    *  In September, the company was issued U.S. Patent No. 7,105,574 covering
       both the novel Vaxfectin(TM) adjuvant and its use with conventional
       vaccines against infectious diseases and cancer.  At the Infectious
       Diseases Society of America (IDSA) conference in October, the company
       presented data from a study in mice showing that the Vaxfectin(TM)
       adjuvant, originally developed to boost the immune response to DNA
       vaccines, also boosts the immune response to a conventional seasonal
       influenza vaccine.  Results from the studies suggest that Vaxfectin(TM)
       has the potential to be used as a dose-sparing agent with conventional
       flu vaccines against seasonal or pandemic flu strains.

    *  Also at the October IDSA conference, the company presented conclusions
       from anthrax DNA vaccine studies in non-human primates, suggesting a
       potential new pathway to evaluation of DNA vaccine efficacy.

    *  The company announced in August that a "prime-boost" vaccine regimen
       tested in 40 HIV-uninfected subjects in a National Institutes of Health
       sponsored Phase 1 clinical trial was safe and well-tolerated, and was
       highly effective in inducing T-cell immune responses with multiple
       functions that may be important for controlling HIV infection.  The
       trial involved priming an immune response with a DNA vaccine based on
       Vical's proprietary technology, and boosting the response with an
       adenoviral vector vaccine at a later date.  The same prime-boost
       vaccine combination is being tested in 480 HIV-uninfected subjects
       through a multinational Phase 2 trial initiated in October 2005.  The
       combination also is being tested in 15 HIV-infected subjects receiving
       highly active antiretroviral therapy (HAART) through a Phase 1 trial
       initiated in August 2006.  A larger multinational Phase 2 trial in
       several thousand HIV-uninfected subjects is expected to begin in
       early 2007.

    *  In September 2006, Vical announced grants of non-exclusive, academic
       licenses for its broad DNA delivery technology patent estate to six
       additional leading research institutions: Fred Hutchinson Cancer
       Research Center, Texas Tech University Health Sciences Center,
       University of Iowa, University of Notre Dame, University of Pittsburgh,
       and University of Washington.  Earlier this year, the company announced
       the grant of academic licenses on the same terms to Stanford
       University, Harvard University, Yale University, and the Massachusetts
       Institute of Technology.

    Forward-Looking Statements

    This press release contains forward-looking statements subject to risks
and uncertainties that could cause actual results to differ materially from
those projected, including: whether the company will achieve levels of
revenues and control expenses to meet projected financial performance; whether
Vical or others will continue development of the influenza vaccine candidate,
the anthrax vaccine candidate, the HIV vaccine candidate, or any other product
candidates being developed by Vical, its collaborators or licensees; whether
Vical or others will continue evaluation of Vaxfectin(TM) as an adjuvant for
conventional vaccines against seasonal or pandemic flu; whether Vaxfectin(TM)
will be used as a dose-sparing agent with conventional flu vaccines; whether
results in animal studies will be predictive of results in human studies;
whether H5N1 or other strains of avian influenza will emerge as pandemic
threats; whether Temasek's investment in the company will generate returns
consistent with its historical returns; whether the company will begin Phase 1
human clinical testing of its pandemic influenza DNA vaccine candidate in
2007, if at all; whether the NIH will begin a Phase 2 trial of several
thousand HIV-uninfected subjects using the company's technology in early 2007,
if at all; whether any product candidates being developed by Vical, its

    Use of Non-GAAP Financial Measure

    This press release contains adjusted net loss projections that are not
calculated in accordance with GAAP. Specifically, the company's adjusted net
loss projection for 2006 excludes an estimated non-cash, stock-based
compensation expense associated with adoption of Statement of Financial
Accounting Standards No. 123R, "Share-Based Payment," on January 1, 2006.
This non-cash expense and is currently estimated at $1 million to $2 million.
As the final amount of such expense cannot yet be determined, the company
currently cannot make a net loss projection in accordance with GAAP or
reconcile its non-GAAP net loss projection to a net loss projection calculated
in accordance with GAAP.

    Vical believes that this non-GAAP financial measure provides meaningful
information regarding the company's performance by excluding expenses that may
not be indicative of the company's core operating results.  In addition, Vical
believes that the use of this non-GAAP financial measure enhances the
consistency and comparability of the company's reported financial results and
enables investors to better evaluate the company's current performance
compared to its past performance.  However, this information should not be
considered in isolation or as an alternative to financial information
calculated in accordance with GAAP.
