Safety of and Immune Response to an HIV Vaccine (VRC-HIVDNA009-00-VP) Administered With Interleukin-2/Immunoglobulin (IL-2/Ig) DNA Adjuvant in Uninfected Adults

Summary

This study will test the safety of and immune system response to a new HIV vaccine. The vaccine in this study is made from HIV DNA produced in a laboratory. Only part of the virus's DNA is used in the vaccine and the vaccine itself cannot cause HIV infection or AIDS. In addition to HIV DNA, the vaccine contains interleukin-2 (IL-2) DNA fused to a portion of immunoglobulin (Ig) DNA. IL-2 is a chemical that stimulates the immune system and may improve response to the vaccine. Study hypothesis: The IL-2/Ig plasmid will be very well tolerated in humans.
