Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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?
