Gel doesn't protect against HIV

New research has revealed that Carraguard microbicidal gel does not protect women from HIV.

Results from a South African trial showed that there was no significant reduction in the rate of infection between a number of women using the gel and those who were not.

In the trial, 6,202 sexually-active women were divided into two groups. Half were given the gel and instructed to use it along with a condom for vaginal intercourse.

After two years it was found that, of the women who were given the gel, 134 had become infected with HIV, while 151 without it had also been infected.

The study report, published in the Lancet medical journal, said: "This study did not show Carraguard's efficacy in prevention of male-to-female transmission of HIV, although no safety concerns were reported.

"Although the results from this and other completed microbicides efficacy trials have been disappointing, the search for female-controlled HIV-prevention methods must continue."
