Description

Induction of CD8+ CTL activity is considered a critical property for a candidate vaccine. Additionally, since the majority of HIV-1 infections occur after inoculation of a mucosal surface, it is desirable to induce mucosal immunity as well as systemic immunity. The HIV p17/p24:Ty-VLP vaccine may potentially induce both CTL and mucosal antibody responses against HIV-1. Volunteers receive HIV p17/p24:Ty-VLP vaccine or placebo by IM injection (with or without alum adjuvant) at months 0, 2, and 6, and then either by mouth or rectal enema at months 10 and 11. Volunteers who receive oral vaccine...

  • Volunteers with the following conditions are excluded:
  • Positive for hepatitis B surface antigen.
  • Medical or psychiatric condition (including recent suicidal ideation or present psychosis) that precludes compliance.
  • 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).

  • Prior Medication:
  • Excluded:
  • Prior HIV-1 vaccines or placebo in an HIV vaccine trial.
  • 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.
  • Experimental agents within the past 30 days.
  • Prior Treatment: Excluded:
