NIAID is conducting and supporting research to develop new strategies to prevent the spread of HIV. These strategies include vaccines and topical microbicides, such as gels, creams, and foams that can be applied to the vagina or rectum prior to sexual intercourse. Another strategy is to provide antiretrovirals to people who are not infected with HIV but who are at high risk of getting HIV infection (called pre-exposure prophylaxis [PrEP]). NIAID is committed to finding scientifically proven HIV prevention strategies and methods that are acceptable for use by different patient populations around the world to combat the HIV/AIDS epidemic.
