An '''HIV vaccine''' is a potential [[vaccine]] that could be either a preventive vaccine or a [[Therapeutic vaccines|therapeutic vaccine]], which means it would either protect individuals from being infected with [[HIV]] or treat HIV-infected individuals. It is thought that an HIV vaccine could either induce an immune response against HIV (active vaccination approach) or consist of preformed antibodies against HIV (passive vaccination approach).<ref>{{cite journal | vauthors = Gray GE, Laher F, Lazarus E, Ensoli B, Corey L | title = Approaches to preventative and therapeutic HIV vaccines | journal = Current Opinion in Virology | volume = 17 | pages = 104–109 | date = April 2016 | pmid = 26985884 | pmc = 5020417 | doi = 10.1016/j.coviro.2016.02.010 }}</ref>

Two active vaccine regimens, studied in the [[RV 144]] and Imbokodo trials, showed they can prevent HIV in some individuals; however, the protection was in relatively few individuals, and was not long lasting. For these reasons, no HIV vaccines have been licensed for the market yet.
