<qa>  What is the name of the vaccine that is formulated with a water soluble polymerEpidemiological and animal model data support the hypothesis that HIV specific cytotoxic T lymphocyte CTL responses contribute to control and clearance of the virus. Vaccines designed specifically to induce CTL responses are likely to be well suited for protection against HIV infection and disease progression. EP HIV-1090 is a DNA vaccine composed of 21 highly specific CTL epitopes. The vaccine is designed to optimize the immune response in people expressing one of three HLA Class I antigen subtypes: HLA-A2, -A3, and -B7. This design is predicted to induce an immune response in 85 of individuals in the general population. There is also a helper T lymphocyte HTL facilitating epitope PADRE in the vaccine. The vaccine is formulated with a water soluble polymer polyvinylpyrrolidone that protects the DNA and facilitates cellular uptake. This study will assess the safety of and immune response to different doses of EP HIV-1090 in healthy, HIV uninfected adults.
