Summary
This study will test the safety and efficacy of an investigational Human Immunodeficiency
Virus (HIV) vaccine. Efficacy will be measured by either prevention of HIV infection or
control of HIV viral load in subjects who become HIV infected.
On September 18, 2007 the Protocol V520-023 DSMB (Data & Safety Monitoring Board) reviewed
data from a planned interim analysis. These data demonstrated that the investigational
vaccine candidate was not effective, and all vaccinations in the study were halted.
Participants were encouraged to continue to come to the clinic for scheduled visits and
ongoing risk reduction counseling since the vaccine was not effective.
