New Vaccine Clears AIDS-Causing Virus in Monkeys

After vaccinating 16 rhesus macaque monkeys, the scientists then infected them with a highly aggressive form of SIV. Nine of the monkeys gradually cleared the virus—the first time this feat has ever been achieved in this avenue of HIV study. After the investigators ground up all of the monkeys’ organs and analyzed 240 samples from each to look for virus, finding none, they pronounced the monkeys cured.
