ClinConnect Summary

Immune responses in HIV-uninfected individuals receiving subunit envelope vaccines formulated with alum adjuvant suggest that functional antibodies capable of neutralizing HIV-1 in vitro may be induced, but the titers are relatively low in comparison to those measured in individuals with natural HIV-1 infection. These limitations might be overcome by the addition or substitution of a more suitable adjuvant such as QS-21.

Volunteers are randomized to 20 treatment arms containing four patients each. rsgp120/HIV-1MN is administered at four dose levels: 0, 100, 300, and 600 mcg, and QS-21 adju...
