Safety of and Immune Response to an HIV-1 DNA Vaccine (VRC HIVDNA009-00-VP) in HIV Uninfected Adults

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to test the safety of and immune response to an HIV-1 vaccine, VRC-HIVDNA009-00-VP, in HIV uninfected participants. Two different doses of the vaccine will be tested.

Detailed Description
-----------------
The worldwide HIV epidemic highlights the importance of developing an affordable, globally successful vaccine for HIV prevention. The VRC-HIVDNA009-00-VP vaccine used in this study was developed to incorporate HIV genes from multiple virus clades, representing the viral subtypes responsible for about 90% of new HIV infections in the world. The purpose of this study is to determine the safety and immunogenicity of VRC-HIVDNA009-00-VP in healthy, HIV uninfected individuals. Participants will be randomly assigned to one of three groups and will be followed for one year. Study injections will be given by needle-free intramuscular injection at the start of study and at Months 1 and 2. Group 1 will receive 3 injections of the study vaccine; Group 2 will receive 2 injections of the study vaccine (at start and Month 2) and injection of placebo (at Month 1); Group 3 will receive 3 injections of placebo. After a screening visit, study visits will occur at enrollment (initial injection) followed by 5 visits every 14 days for the first 2.5 months, with three additional visits at Months 6, 9, and 12. All participants will undergo physical exams, blood and urine tests to assess measures of health, and blood tests to assess HIV infection and immune response to the injections.
