It's neat that they finally made one that affects all races, but this is hardly new news: link. First link of google I clicked on searching for: "aids vaccine Caucasians". I read information about this at least ten or more years ago where scientists had already developed a vaccine, but that it mostly only worked for those of Negro genealogy. It was in every major newspaper for only one day, then quietly disappeared. My friends and I contemplated it's fate, assuming the vaccine was never fully ready for humans or something, but the possibility that it was shelved because it did not work for all races did cross our minds since it's common knowledge that the FDA won't approve a drug unless it works on a large percentage of the entire population.
