Human viral infections are controlled by the immune system. However, the multiple immune responses provoked by HIV infection do not control the infection in most people. The ability to specifically augment CTL responses with an immunotherapeutic vaccine may strengthen the containment of viremia afforded by antiretroviral agents and thereby extend the durability of viral suppression. The current study will attempt to determine whether therapeutic immunizations with HIV-1 immunogen and vCP1452 are safe and able to augment HIV-1 specific immune responses for a longer period of time than antiretroviral therapy alone, and if both agents are better than either by itself.
