Scientists say vaginal gel cuts HIV-infections by half

Women in the trial are said to have used the gel largely as directed
A microbicidal vaginal gel has significantly cut the rate of women contracting HIV from infected partners in an experiment in South Africa.

The gel, containing the Aids drug tenofovir, cut infection rates by 50% after one year of use, and by 39% after two and a half years, researchers said.
If the results are confirmed it would be the first time that a microbicidal gel has been shown to be effective.

Such a gel could be a defence for women whose partners refuse to wear condoms.
