Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To determine the reactivity and safety of HIV-1 recombinant envelope glycoprotein gp160. To determine the immunogenicity of gp160.

Although recent advances have been made in antiviral therapy against AIDS, there is currently no cure. It is likely that ultimate control of the disease will depend on the development of safe and effective vaccines against HIV.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Although recent advances have been made in antiviral therapy against AIDS, there is currently no cure. It is likely that ultimate control of the disease will depend on the development of safe and effective vaccines against HIV.

Healthy volunteers are injected on days 0, 30, and 180 with one of four preparations: gp160 vaccine (40 mcg), gp160 vaccine (80 mcg), hepatitis B vaccine, and placebo. The hepatitis B vaccine group will serve as an additional control for immunological evaluations. An optional fourth injection may be given 15-21 months following the initial inoculation.

Subjects with the following prior conditions are excluded:

* History of immunodeficiency, chronic illness, or use of immunosuppressive medications.
* Prior hepatitis B vaccination.
* Syphilis, gonorrhea, or any other sexually transmitted diseases (including chlamydia or pelvic inflammatory disease) in the past 6 months.
