GeoVax Labs, Inc. Second Quarter Financial Results and Operational Update

ATLANTA, Aug. 14 /PRNewswire-FirstCall/ -- GeoVax Labs, Inc. (OTC: GOVX) (BULLETIN BOARD: GOVX) , an Atlanta-based biotechnology company (the "Company"), today announced its financial results and provided an operational update for the quarter ended June 30, 2007.

Operating Results for the Quarter Ended June 30, 2007

The Company recorded a net loss of $1,333,126 for the three months ended June 30, 2007, compared to net income of $197,750 for the same period in 2006. For the six months ended June 30, 2007, the Company's net loss was $1,920,407 as compared to a loss of $143,456 in 2006. The increase in the net loss during 2007 is attributable to (a) no grant revenues recorded during 2007 as the Company progressed beyond basic research and into product development activities, (b) higher research and development expenses as the Company continued to support its four ongoing Phase I human clinical trials and prepares for initiation of Phase II studies, and (c) overall higher general and administrative expenses primarily due to the additional costs associated with being a public company subsequent to the merger between Dauphin Technology, Inc. and GeoVax, Inc. in September 2006. As of June 30, 2007, the Company reported cash balances totaling $1,009,302.

See the summarized financial information attached. Further information concerning the Company's financial position and results of operations are included in its Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission.

  Recent Operational Highlights:

   * In July, GeoVax announced an early start of two new HIV/AIDS vaccine
     clinical (human) trials. These FDA compliant trials were previously
     scheduled to start later in 2007 and are the 3rd and 4th in a four
     clinical trial series intended to evaluate both human safety and immune
     responses to GeoVax's HIV/AIDS vaccines. Starting April 2006, the 1st
     of these four trials evaluated a low dose (1/10th of the vaccine dose)
     vaccination program. Preliminary results from this blinded trial
     demonstrated excellent vaccine safety and positive anti-HIV-1 immune
     responses to the vaccine in 9 of 11 participants where 9 people
     received GeoVax HIV/AIDS vaccines and 2 received placebos. All trial
     participants were normal, healthy individuals. Final results will be
     compiled for later public release. The 2nd of four trials, initiated
     September 2006, is designed to evaluate results from full dose a
     administration of GeoVax HIV/AIDS vaccines. Recent data indicates
     excellent safety in this full dose trial with immune response data soon
     to be available.

   * In June and July, GeoVax announced it engaged Althea Technologies,
     Inc., and BioReliance Corporation, as contract manufacturers for its
     HIV-1 DNA and HIV-1 MVA (AIDS) vaccines.  These vaccines will be
     utilized in GeoVax's advanced Phase 2 clinical trials planned for early
     2008. GeoVax HIV/AIDS vaccines are designed to prevent development of
     Acquired Immunodeficiency Disease (AIDS) caused by the virus known as
     HIV-1 by vaccinating individuals prior to AIDS virus infection. The
     vaccine regimen employs a two-vaccine "prime-boost strategy." Trial
     participants will be administered GeoVax HIV-1 DNA vaccine which
     "primes" the immune system followed by GeoVax's HIV-1 MVA (Modified
     Vaccinia Virus) boost. Both vaccines deliver over 50% of the AIDS virus
     components but can not cause AIDS. Safety and immunological results
     from earlier as well as ongoing human trials are very encouraging thus
     supporting planned acceleration of large scale Phase 2 clinical
     studies.

   * In April, GeoVax announced an extension of a research license signed
     4/2005 with Vivalis (Nantes, France) to evaluate Vivalis' EBx(R) cell
     lines (avian embryonic derived stem cell lines) for the production of
     GeoVax's MVA (Modified Vaccinia Ankara) based HIV/AIDS vaccines.
     Results obtained from Vivalis and GeoVax demonstrated that EBx(R) cell
     technology is possibly a more economical alternative to chicken
     embryonic fibroblasts (CEFs) for the replication of GeoVax specific
     recombinant MVA based AIDS vaccines. Simultaneously, GeoVax's promising
     results in preclinical trials as well as encouraging and positive
     immune response data from two ongoing human trials provided the impetus
     for accelerating clinical evaluations of GeoVax's vaccines and for
     considering the EBx(R) cell platform in industrial vaccine production.
     Vivalis and GeoVax collaborations focus on scaling-up MVA based
     HIV/AIDS vaccine production processes in EBx(R) cells. In addition,
     Vivalis plans preparation of an EBx(R) platform Biological Master File
     for filing with the FDA. In parallel, GeoVax is evaluating plans for an
     immunogenicity comparability study of GeoVax's MVA based HIV/AIDS
     vaccines produced in CEFs and those produced in EBx(R) cells. This
     information may be presented in a pre-IND meeting with the FDA
     concerning potential use of this cell line.

  Management Commentary

Donald Hildebrand, Chief Executive Officer of GeoVax, commented, "Recent developments at GeoVax encourage and excite us as we continue working toward our ultimate goal of making available a safe and effective vaccine for the prevention of AIDS. We are particularly encouraged by the recent accelerated start date of our two new human clinical trials, resulting primarily from the excellent safety and anti-HIV immune response results obtained to date from our ongoing 1/10th and full dose vaccine trials. We are also pleased with the positive response to our progress at GeoVax as reflected by our recent financing announcement. This substantial $7.5 million investment will enhance our HIV/AIDS vaccine development and human clinical trials program, thus allowing us to push forward into large scale Phase 2 AIDS vaccine trials involving many more human participants."
