Vaginal Gel Might Prevent HIV Hours After Exposure
Lab tests with monkeys look promising, study says
The team then tested whether the gel could protect against HIV infection after exposure, using six monkeys exposed to HIV twice a week for two and a half months. By applying the gel three hours after exposure, researchers were able to protect five of the six monkeys from HIV infection. All four monkeys in the placebo group contracted HIV.
Such a gel, once through its clinical trials and approved, could become as widely used as birth control devices such as condoms and spermicidal gels, Johnston said.
"You can imagine this to be a useful product to have, if it were something you could buy over the counter and have at home just in case," she said.
