Brief Summary

This study will evaluate whether an experimental vaccine intended to prevent HIV infection is safe and whether it causes any side effects. It will also examine whether the vaccine, called VRC-HIVDNA016-00-VP, causes an immune response, and will monitor participants for the social impact of being in an HIV vaccine study. VRC-HIVDNA016-00-VP contains synthetic DNA that codes for parts of four HIV proteins. It also contains a "promoter" piece of DNA that is needed to start protein production. The promoter DNA is also synthetic and is like the promoter in another virus called cytomegalovirus (CMV). The vaccine contains no live HIV virus or CMV and cannot cause either of these illnesses. Healthy volunteers between 18 and 44 years old who are HIV-negative may be eligible for this 32-week study. Candidates are screened with a medical history, physical examination, and blood and urine tests. Participants receive three injections of the experimental vaccine approximately 28 days apart. The injections are given with a system called the Biojector 2000 that delivers the vaccine through the skin into the muscle without the use of a needle. Subjects are observed for side effects for at least 30 minutes after each vaccination and are required to telephone the clinic staff 1 to 2 days after the injection to report how they are doing. In addition, they are given a diary card to take home, on which they record their temperature and any symptoms daily for five days. Participants return to the clinic two weeks after each injection. They return the completed diary card and are checked for any health changes or problems since the last visit. They are asked how they are feeling and what medications, if any, they have taken. Blood and urine samples are collected. Some subjects may be asked to have laboratory tests between regular visits if needed to evaluate a change in health. Participants are also asked about any social effects they may have experienced as a result of their participation in the study.
