Why is a vaccine critical in the fight against HIV?

Robert Gallo, M.D. (Founder, Institute of Human Virology (IHV)) gives expert video advice on: How can a successful HIV vaccine be created?; Is it important to test for HIV across all races and genders?; Can HIV or AIDS be cured? and more...

We have to get rid of the virus and the way we're going to get rid of it is medical science solves it and that's a preventive vaccine. That won't help, very likely, the people who are already infected, they'll need to be treated and taken care of. But if a preventive vaccine is successful it means that nobody else will get infected or at least the reduction will go way down and the epidemic will gradually disappear.
