Immune Responses in HIV-Positive Patients Receiving an Anti-HIV Drug Combination When Given the HIV Vaccines Remune and vCP1452

The purpose of this study is to see how the vaccines Remune (HIV-1 immunogen) and vCP1452 affect immune responses in patients who also are taking anti-HIV medications. This study also will see if these vaccines are safe to use either alone or in combination. Treatment with anti-HIV drugs does not always keep HIV viral load low and under control. This study will look at the effect of the HIV vaccine, vCP1452, on the immune response and how it works in combination with Remune. Information about immune responses and the safety of these vaccines in HIV-positive patients will be gathered.
