Brief Summary | To determine if priming (giving the first vaccination) with a vaccinia recombinant (HIVAC-1e) provides a significant advantage in immunogenicity (production of antibodies) compared to priming with a soluble recombinant protein (gp160); to learn more about the safety of the combination use of the two HIV envelope vaccines utilized in the study. Recent studies at the AIDS vaccine units have shown the safety of two candidate HIV vaccines, HIVAC-1e and gp160. Specific questions to be addressed in this part of the study include: Does combination vaccination result in a synergistic (added) response not predicted by just the addition of a second vaccination, and does this synergism depend on the unique priming effect of a vaccinia recombinant, or will any combination do? |

Detailed Description | Recent studies at the AIDS vaccine units have shown the safety of two candidate HIV vaccines, HIVAC-1e and gp160. Specific questions to be addressed in this part of the study include: Does combination vaccination result in a synergistic (added) response not predicted by just the addition of a second vaccination, and does this synergism depend on the unique priming effect of a vaccinia recombinant, or will any combination do? Volunteers will be randomized to one of four groups. Group A (20 volunteers) will receive gp160 (VaxSyn) followed two months later by a repeat dose. Group B (20 volunteers) will receive VaxSyn followed two months later by HIVAC-1e. Group C (20 volunteers) will receive HIVAC-1e followed two months later by VaxSyn. Group D (10 volunteers) will receive HIVAC-1e followed two months later by HIVAC-1e. For volunteers in Groups A, B, and C who do not react to the initial vaccination, a second attempt to obtain a reaction may be made 7 or more days following the initial inoculation. Per addendum, two additional booster inoculations are given: one at 6 months or later post initial inoculation (Groups A, C, and D receive VaxSyn and Group B receives HIVAC-1e) and another at 12 months or later (all Groups receive VaxSyn). |
