Drug-coated ring cuts HIV risk by more than half in some women

By Gene Emery (Reuters Health) – An experimental drug-infused ring inserted in the vagina once a month cut the odds of becoming infected with HIV by more than half among women who used the device consistently, in a study in four African countries where the risk of AIDS is high. “Use of the product was enough to demonstrate HIV protection of 27 percent” over placebo, chief author Dr. Jared Baeten, a professor of medicine and global health at the University of Washington in Seattle, told Reuters Health by phone. “And in some groups of women who appeared to use it better, such as women over age 21, the risk of HIV was reduced by more than half.” Such silicone rings, infused with a different drug, are already used for birth control.
