Microbicides

The term “microbicide” refers to substances being studied that could be used in the vagina and/or rectum to reduce the risk of HIV infection via sexual exposure. Today, daily oral PrEP is the only HIV prevention tool for women that does not require partner negotiation at or around the time of sex. Access to PrEP is expanding, but more options are needed. Easy-to-use microbicides would fill an important HIV prevention need. They can be used discreetly and their effect is localized to the site of infection (the rectum or vagina) and not systemic (affecting the whole body), characteristics some people will prefer.

A range of microbicide strategies are under investigation, including gels, douches and the dapivirine vaginal ring, which is being considered for licensure. Developed by the International Partnership for Microbicides (IPM), the ring would be the first microbicide and the next prevention tool available since oral PrEP’s approval in 2012. For the latest developments in dapivirine ring research and plans for potential rollout, visit the dapivirine ring page on PrEP Watch.

After years of uncertainty and delays, the European Medicines Agency provided a positive scientific opinion about the ring. This decision places the ring on the path toward regulatory approval, so that globally, women who need protection from HIV have more options.
