Participants should not expect to be protected from HIV by these study vaccines. In fact, participants may not even get the study vaccines in this study, since some participants (approximately half) will get a placebo. A placebo is a product that contains no study vaccine, but sterile salt water.
This study is designed to find out if the study vaccines work to prevent or fight HIV. However, more studies may need to be done to learn if they do.
Because we don’t know if the study vaccines will prevent HIV/AIDS, participants in this study will be counseled on how to avoid behavior that will put them at risk of HIV infection.
