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.
