HIV Vaccine Awareness Day

May 18

HIV Vaccine Awareness Day (HVAD) recognizes the many volunteers, community members, health professionals, and scientists working together to develop a vaccine to prevent HIV. It is also an opportunity to educate communities about the importance of preventive HIV vaccine research. Held annually on May 18, the observance commemorates U.S. President Bill Clinton’s 1997 declaration that “only a truly effective, preventive HIV vaccine can limit and eventually eliminate the threat of AIDS.”

The National Institutes of Health (NIH) HIV research program, coordinated by the NIH Office of AIDS Research (OAR), supports research to develop an effective HIV vaccine, as well as research on strategies to encourage people to receive an HIV vaccine when it is available. Researchers are making promising headway in efforts to develop a safe, effective HIV vaccine. These include vaccine candidates that:

Uses broadly neutralizing antibodies (bNAbs), a type of antibody that can recognize HIV and block the virus from entering immune cells.
Help generate an HIV-specific immune response through T cells, a type of white blood cell, that can recognize HIV and help prevent chronic infections.
Leverage messenger RNA (mRNA) platforms to help the immune system recognize, remember, and respond to the virus.

Insights from HIV vaccine research help spur groundbreaking advances in other areas of science and health care. Most recently, these insights provided a foundation for rapid development of COVID-19 vaccines.

The NIH HIV Strategic Plan provides a roadmap for the National Institutes of Health (NIH) to guide HIV-related research and direct HIV research funding to the highest-priority areas to help end HIV. NIH supports research to develop an effective vaccine, as well as research on strategies to encourage people to receive an HIV vaccine when it is available.
NIH Statement on HIV Vaccine Awareness Day 2023: This NIH statement, jointly issued by OAR and the NIH National Institute of Allergy and Infectious Diseases (NIAID), recognizes the collaborative global community of scientists, advocates, study participants, study staff, and funders enabling unprecedented levels of innovation and adaptation in the pursuit of a highly effective HIV vaccine. The statement summarizes current NIH-supported HIV vaccine research and reaffirms NIH’s commitment to the development of an effective, acceptable, safe, and long-lasting HIV vaccine.
This OAR webpage describes how NIH-funded research is helping to reduce the incidence of HIV through clinical trials to test effectiveness of potential HIV vaccines, as well as through research to advance other nonvaccine prevention methods.

HIV Vaccine Trials Network (HVTN)

The HIV Vaccine Trials Network (HVTN) is the world’s largest publicly funded multidisciplinary international collaboration facilitating the development of vaccines to prevent HIV. HVTN conducts all phases of clinical trials, from evaluating experimental vaccines for safety and immunogenicity to testing vaccine efficacy. HVTN receives support through a collaborative agreement with the NIAID Division of AIDS (DAIDS).
