HIV Vaccine

An HIV vaccine is designed to stimulate the immune system to recognize and fight the HIV virus, which causes AIDS. It introduces harmless parts of the virus or similar components to trigger an immune response without causing illness. If vaccinated people later encounter HIV, their immune system can respond more quickly and effectively, reducing the chance of infection or decreasing the severity if infection occurs. Developing such a vaccine is complex due to the virus’s ability to mutate rapidly, but advances aim to provide protection and help control the global HIV/AIDS epidemic.
