HIV/AIDS BackgroundHIV affects the entire globe and comes in a variety of subtypes. Clade B is the predominant subtype in North America where there are roughly 60,000 new infections each year. Globally, there are about 2.5 million AIDS infections per year, most primarily involving subtypes AG, B, and C. In 2007, UNAIDS reported 1.3 million people living with AIDS in North America and 33.2 million people living with AIDS worldwide. Presently, there is little to prevent HIV transmission other than education, circumcision, and condoms. It is obvious from the spread of the disease that these methods are not adequate. Existing treatments for individuals infected with HIV include anti-retroviral therapies that are effective but have serious medical side effects and are very expensive (upwards of $1,500/month). This cost is borne primarily by the individual and sometimes by third party insurance, local healthcare, federal or world health organizations. Development and distribution of an effective HIV/AIDS vaccine holds great promise. The GeoVax vaccine would cost a fraction of the cost of current treatments and, to date, has not elicited serious adverse side effects in several human trials. A population vaccinated with an effective HIV-1 vaccine would be expected to significantly decrease the prevalence of AIDS over time.
