A vaginal gel has significantly cut the rate of women contracting HIV from infected partners in an experiment in South Africa, researchers said.
They said the gel, containing Aids drug tenofovir, cut infection rates among 889 women by 50% after one year of use, and by 39% after two and a half years.
If the results are confirmed it would be the first time that a microbicidal gel has been shown to be effective.
