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.
