Brief Summary

To determine the safety and immunogenicity of 200 mcg MN rgp160 vaccine (Immuno-AG) versus placebo, administered on two immunization schedules to healthy volunteers. Per 06/15/94 amendment, to determine the safety and immunogenicity of 800 versus 200 mcg given as a fourth immunization at 9 or 11 months after the third injection (i.e., at month 17). A gp160 vaccine developed from the IIIB strain of HIV-1 has been found to be safe and immunogenic in healthy adults. Since the MN strain of HIV-1 is representative of a larger proportion of HIV-1 isolates in the United States than is the IIIB strain, evaluation of a gp160 vaccine derived from the MN strain is important.

You may not qualify if:

  • Co-existing Condition:
  • Subjects with the following conditions are excluded:
  • Positive for hepatitis B surface antigen.
  • Medical or psychiatric condition or occupational responsibilities that preclude compliance.
  • Active syphilis (NOTE: If serology is documented to be a false positive or due to a remote (\> 6 months) infection, subject is eligible).
  • Active tuberculosis (NOTE: Subjects with a positive PPD and normal x-ray showing no evidence of TB and who do not require INH therapy are eligible).
  • Subjects with the following prior conditions are excluded:
  • History of anaphylaxis or other serious adverse reactions to vaccines.
  • Prior Medication:
  • Excluded:
  • Prior HIV vaccines.
  • Live attenuated vaccines within the past 60 days. NOTE: Medically indicated subunit or killed vaccines (e.g., influenza, pneumococcal) do not exclude but should be administered at least 2 weeks prior to HIV immunizations.
