Immune Responses to Two Experimental HIV Vaccines in Healthy Adults
The primary focus of the Vaccine Research Center (VRC) at the NIH is to develop vaccines for HIV/AIDS. The main purpose of this study is to look in detail at the body's immune response to two experimental HIV vaccines currently in development at the VRC. One is known as the rAd5 vaccine and the other is known as the DNA vaccine. These vaccines are made with pieces of manufactured DNA. They do not contain live or killed HIV. It is impossible for study vaccines to give you HIV and they cannot cause you to give HIV to someone else. Both of these experimental vaccines have been given to people before in other research studies. They have not been approved for treating or preventing HIV infection.
The main purpose of this study is to look in detail at the body's immune responses after the experimental HIV vaccines are given and to assess safety of the study vaccines.
Healthy volunteers between the ages of 18 and 50 who are not infected with HIV and who meet the eligibility requirements.
Participants will be screened with a medical history (including questions about sexual history and drug use), physical exam, and blood tests.
The study will have two groups:
(Bullet) One group will receive one injection of the rAd5 vaccine, and have 8 clinic visits over 3 months.
(Bullet) The second group will have three injections of the DNA vaccine, one injection of the rAd5 vaccine, and have 12 clinic visits over 6 months.
All participants will be asked to provide blood and body fluid samples for testing during the study.
Payment for participation will be provided.
