HIV/AIDS Vaccines

The long-term aim is to develop a nontoxic and effective vaccine that defends people worldwide after getting infected with HIV. However, even if a vaccine only defends some people who get vaccinated, or even if it affords less than total protection by reducing the threat of infection, it could still have a major impact on the rates of transmission and help control the pandemic, particularly for populations at high risk of HIV infection. A partially effective vaccine could decrease the number of people who get infected with HIV, further reducing the number of people who can pass the virus on to others. By considerably reducing the number of new-fangled infections, we can stop the widespread.
