Phase III HIV Vaccine Study

Janssen Vaccines and Prevention B.V., the HIV Vaccine Trials Network (HVTN), and the New York Blood Center (NYBC) are doing a study to test a combination of HIV vaccines. HIV is the virus that causes AIDS.

We want to see if the vaccines prevent people from getting HIV. We also want to see if the vaccines are safe to give to people and do not make them too uncomfortable.
