A Dapivirine vaginal ring to be used in an HIV prevention trial on July 20, 2012 in JohannesburgA monthly vaginal ring that contains an anti-retroviral drug has been shown to cut the risk of HIV infection in women by nearly one-third, according to two international studies Monday. The dapivirine ring was even more effective in women over 25, who saw their risk of HIV drop 61 percent while using the ring, developed by the nonprofit International Partnership for Microbicides (IPM). The findings, released at the Conference on Retroviruses and Opportunistic Infections (CROI) in Boston, mark the first time a long-acting vaginal ring has been shown to significantly reduce the risk of HIV infection in women, researchers said.
