HIV vaccine refers to the vaccine for HIV, and there is no such vaccine available yet, so if a person wants to get an HIV vaccine, there is no way to go about it. If there is such a vaccine available in the future that can prevent getting AIDS, it is certainly necessary to get the shot because it can prevent the disease. Although AIDS can be controlled with a cocktail of antiviral drugs after infection, there is no way to completely cure AIDS, so it is certainly better if a vaccine can prevent it. The main method of preventing AIDS is to avoid contact with the source of infection and to cut off the transmission route, the source of infection is mainly AIDS patients, and the transmission route is clinically more common through sexual transmission.
