What Is a Preventive HIV Vaccine?
A preventive HIV vaccine is given to people who do not have HIV, with the goal of preventing HIV infection in the future. The vaccine would teach the person's immune system to recognize and effectively fight HIV in case the person is ever exposed to HIV.
Are There Any FDA-Approved Preventive HIV Vaccines?
There are currently no preventive HIV vaccines approved by the Food and Drug Administration (FDA), but research is under way. You must be enrolled in a clinical trial to receive a preventive HIV vaccine.
How Is a Preventive HIV Vaccine Different From a Therapeutic HIV Vaccine?
While a preventive HIV vaccine is given to people who do not have HIV, a therapeutic HIV vaccine is given to people who already have HIV. The goal of a therapeutic HIV vaccine is to strengthen a person's immune response to the HIV that is already in the person's body. Researchers are exploring therapeutic HIV vaccines:

Can I Get HIV From a Preventive HIV Vaccine?
No, you cannot get HIV from a preventive HIV vaccine. The preventive HIV vaccines being studied in clinical trials do not contain HIV. Of the approximately 30,000 people who have participated in HIV vaccine studies around the world in the last 25 years, no one has gotten HIV from any of the vaccines tested.
Why Is a Preventive HIV Vaccine Important?
Treatment options for HIV infection have improved a lot over the last 30 years. But HIV medicines can have side effects, can be expensive, and can be hard to access in some countries. Also, some people may develop drug resistance to certain HIV medicines and then must change medicines.
Current prevention tools for HIV, such as using condoms correctly and pre-exposure prophylaxis (PrEP), work well. But researchers believe a preventive HIV vaccine will be the most effective way to completely end new HIV infections.
What Research Is Being Done on Preventive HIV Vaccines?
Some of the areas of interest being studied in clinical trials include:
