HIV is a very complex, highly changeable virus, which makes speedy development of a successful preventive HIV vaccine very difficult, but not impossible.  It also takes many years to conduct the research, including the careful clinical testing that will lead to a safe and effective vaccine.

Researchers from around the world have been working for more than two decades to create a vaccine that will protect people against HIV infection. NIAID supports the HIV Vaccine Trials Network (HVTN), an international collaboration of scientists and educators searching for an effective and safe HIV vaccine.
