Cure for HIV

Just saw this on my news feed, there is a plethora of articles coming out right now. If they are able to get this “cure” perfected, how do you think it’ll impact society? How long do you think it will take to be perfected? The last, and first, patient was apparently cured 12 years ago. We now are on patient two who has been supposedly cured. Do you think they may make it into a standard vaccine at a later date to combat it entirely or to only give after positive infection?
