Description

Active immunization of HIV-infected women during pregnancy may slow the progression of maternal disease, reduce the titer of virus in maternal plasma, and increase the titer of epitope-specific antibody. Also, active immunization has the potential to induce primary immunity in the fetus and to boost both T-cell and humoral immune responses to HIV in the mothers. Women are randomized to receive rgp120/HIV-1SF2 vaccine or MF59 placebo. Patients receive the first immunization between 16 and 24 weeks gestation and monthly thereafter until delivery, for a maximum of five immunizations. Patients...
