Brief Summary:
The purpose of this study is to see if an HIV vaccine, AIDSVAX B/B, can protect adults who are at risk from becoming infected with HIV. Patients who become infected despite immunization will be studied to see if receiving the vaccine before becoming infected will help keep HIV levels (viral load) low.

Condition or disease Intervention/treatment Phase
HIV Infections HIV Seronegativity Biological: MN rgp120/HIV-1 and GNE8 rgp120/HIV-1 Phase 3

Detailed Description:
Volunteers receive 7 blinded, intramuscular vaccinations (at Months 0, 1, 6, 12, 18, 24, 30) containing either the AIDSVAX B/B vaccine or a placebo (aluminum adjuvant only). Volunteers are randomized in a 2 to 1 vaccine-to-placebo ratio. HIV-uninfected persons are followed for a total of 16 visits beginning at screening and continuing until Month 36. Patients who become HIV infected during study are followed every 4 months for at least 24 months.
