AMENDED 11/17/93: To determine whether the pattern of response to MN rgp120 vaccine is altered by pre-exposure to IIIB rgp120. ORIGINAL DESIGN: To evaluate the safety (clinical and immunologic) of rgp120/HIV-1IIIB vaccine (gp120 vaccine) immunization in healthy HIV-1 seronegative adult subjects. To compare the immune response to 100 mcg gp120 vaccine versus 300 mcg gp120 vaccine. To determine whether gp120 vaccine immunization causes a significant immune response as defined by specific parameters (e.g., induction of neutralizing antibodies to the IIIB isolate of HIV-1, gp120 antigen-specific lymphocytic proliferation). Recent evidence suggests that gp120 is the HIV-1 protein with the greatest potential as a vaccine against HIV-1 infection. The gp120 envelope protein may be produced by recombinant DNA technology, and studies have shown that the vaccine is capable of eliciting neutralizing antibody activity in both rodents and nonhuman primate species.
