Brief Summary:

Background:

HIV stands for human immunodeficiency virus, which is the virus that causes AIDS. There is currently no licensed vaccine to prevent HIV infection. Researchers want to test a vaccine called Trimer 4571 for the first time. It was made at the National Institutes of Health and contains no HIV. It will be given mixed with a substance called alum to boost the body s immune response to the vaccine. Alum has been used in licensed vaccines for over 60 years and has been found to be safe.

Objectives:

To see if the vaccine Trimer 4571 is safe, well-tolerated, and to study immune responses to it.

Eligibility:

Healthy adults ages 18-50 years

Design:

Participants will be screened with a physical exam and blood tests. They must agree to not become pregnant and to avoid behavior that will put them at high-risk for HIV infection during the study.

Participants will have about 15 study visits over about 9 months.

The first 6 participants will get a low dose of the vaccine mixed with alum.

Once that is deemed safe, 10 new participants will get a higher dose.

All participants will be randomly assigned to get the vaccine by injection in a muscle or under the skin.

All participants will get a total of 3 vaccine injections over 20 weeks. Each visit where participants receive the vaccine will last about 5 hours. Participants will be watched after each injection. Participants able to get pregnant will have a pregnancy test before each injection.

Participants will get a thermometer and record their temperature and symptoms every day for 1 week after each injection. They will also check the injection site for redness, swelling, or bruising.

At follow-up visits, participants will have blood drawn and be checked for health changes or problems. Follow up visits will last about 1-2 hours.
