GEOVAX LABS RELEASES UPDATE LETTER TO SHAREHOLDERS ATLANTA - January 15, 2013 - Robert T. McNally, Ph.D., President & CEO of GeoVax Labs (OTCQB: GOVX), along with David A. Dodd, Chairman of the Board, today issued the following update letter to shareholders:

Dear Fellow Shareholders,
Since our last shareholder update letter in May 2012, we have continued the steady progress of the clinical development of HIV/AIDS vaccines for both therapeutic and preventive applications. As we begin a new year, we are pleased to provide you this brief update on recent developments at GeoVax and our plans for 2013 and beyond.

Therapeutic HIV/AIDS Vaccine

As we have noted before, of the 1.2 million Americans infected with HIV, only 30 percent have successfully suppressed their infection using drugs. Thus, there is a need for simpler therapies to control HIV infections.
