Safety of and Immune Response to an HIV Preventive Vaccine (HIV-1 Gag DNA Alone or With IL-15 DNA) Given With or Without 2 Different Booster Vaccinations in HIV Uninfected Adults

Summary

The purpose of this study is to determine the safety of and immune response to an experimental HIV vaccine, HIV-1 gag DNA, with and without an IL-15 DNA adjuvant (at escalating doses of 100, 500, and 1500 mcg). This study will also test the safety of and immune response to the HIV-1 gag DNA vaccine plus IL-15 DNA adjuvant given with or without 2 other adjuvant-containing booster vaccines.
