A Phase I/II Trial of Vaccine Therapy of HIV-1 Infected Individuals With 50-500 CD4 Cells/mm3

Summary

To examine the response of HIV-1 infected patients to vaccination with gp120/HIV-1MN antigen. To determine the effect of antiretroviral therapy on vaccine responsiveness. Fifty percent of HIV-1 infected individuals remain symptom free for 8-12 years. It has been hypothesized that HIV-specific immune responses are responsible for the period of relative quiescence of viral replication. Recent studies suggest that these immune functions can be augmented by vaccination with HIV-derived antigens.
