Even a partially effective HIV vaccine could save millions of lives. Experts have calculated that a vaccine that is 50 percent effective, given to just 30 percent of the population could reduce the number of HIV infections in the developing world by more than half over 15 years. An HIV vaccine that was more than 50 percent effective could cut the infection rate by more than 80 percent.
The long-term goal is to develop a safe and effective vaccine that protects people worldwide from getting infected with HIV.
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.
HIV Vaccines
HIV Vaccine
Vaccines stimulate the body’s immune system to provide protection against infection or disease.
An HIV vaccine does not yet exist, but efforts to develop a vaccine against HIV, the virus that causes AIDS, have been underway for many years.
HIV (Human immunodeficiency virus) is the virus which causes AIDS, the disease which affects the immune system of the body.
