ATLANTA, GA., November 12, 2013 - GeoVax Labs, Inc. (OTCQB: GOVX), a biotechnology company developing vaccines to prevent and treat HIV/AIDS, today reported financial results and recent developments for the three and nine months ended September 30, 2013.

GeoVax reported a net loss of $190,148 ($0.01 per share) for the three months ended September 30, 2013, compared to $296,779 ($0.02 per share) for the same period in 2012. For the nine months ended September 30, 2013, the Company's net loss was $1,413,229 ($0.07 per share) as compared to $1,525,055 ($0.09 per share) in 2012.

Recent Developments and Highlights

"This is a crucial and exciting time for GeoVax. We have important near-term milestones ahead of us, including the completion of two key Phase 1 clinical trials" said Robert McNally, PhD, GeoVax's President and CEO. "As we enter 2014, we will continue to place emphasis in the success of our clinical progress. Our relationship with the HVTN and the NIAID remains strong, and we should be entering into a Phase 2a trial with our preventive vaccine in mid-2014. We also plan to initiate a second Phase 1 trial with our therapeutic vaccine in 2014. As other HIV vaccines have fallen by the wayside over the past several years, GeoVax continues to move forward with what we believe will be a successful approach to HIV prevention and treatment through effective vaccination."

About GeoVax's Technology

GeoVax's unique, two component vaccine, a recombinant DNA and a recombinant modified vaccinia Ankara (MVA), is designed to stimulate both anti-HIV T cell and anti-HIV antibody immune responses. GeoVax's DNA and MVA vaccines are used in a prime/boost protocol in which priming is done with the DNA and boosting with the MVA. Both the DNA and MVA express the three major proteins of the AIDS virus: Gag, Pol, and Env, and produce non-infectious virus-like-particles. GeoVax's vaccines are unique in expressing virus-like particles that display the trimeric membrane bound form of the HIV-1 envelope glycoprotein. In GeoVax's second generation vaccine, the DNA prime co-expresses GM-CSF with the virus-like particles, delivering a normal human protein that stimulates immune responses to the site of vaccination. All preventative Phase 1 human clinical trials conducted to date tested various combinations and doses of our DNA and MVA vaccines, their ability to raise anti-HIV humoral (antibody) and cellular (cytotoxic T cell) immune responses, as well as the vaccines' safety.

AIDS can affect anyone, regardless of race, gender, age or sexual orientation. 33 million people are currently infected globally and it is estimated that there will be 2.5 million new infections this year. Since the beginning of the epidemic, over a million people in the U.S. have contracted the virus. Every 9 minutes, someone in the U.S. is infected with AIDS. Globally, HIV is the top killer among women of reproductive age. HIV is a worldwide disease with different subtypes (or clades) of the virus predominating in different regions of the world. Clade B is the predominant subtype in North America. Globally, most infections involve Clades AG, B, and C. GeoVax most advanced vaccines under development are designed to function against Clade B.
