Study Summary
Vaccines have been very successful in preventing viral infections such as hepatitis B and the measles. Viral vaccines work by causing a person's immune system to make cells that will work against the virus. Due to the success in treating other viral infections, scientists are trying to develop a vaccine for human immunodeficiency virus (HIV). HIV infection is the cause of acquired immune deficiency syndrome (AIDS). AIDS is one of the most serious viral infections we know. This is a research study to evaluate the safety of a possible vaccine against HIV. Researchers want to determine that a person's immune system can respond to the HIV before he or she is exposed to it. Therefore that person may be able to be protected from infection with HIV.
