What is the HIV Vaccine and Is HIV Vaccine Useful?

An HIV vaccine may have the goal of protecting people who do not have HIV from being infected with the virus or treating an HIV-infected person.

Well, currently there is no licensed HIV vaccine for HIV but there are multiple research projects that are trying to find an effective vaccine for the infection. Some, but absolutely not all, HIV-infected individuals usually produce broadly neutralizing antibodies which keep the suppressed virus and these people remain asymptomatic for years.

Some neutralizing antibodies have been cloned in the monoclonal antibodies and are being tested in passive vaccination clinical trials.
