NIH-Funded Study Finds Protective Effect Strongest in Women over Age 25
A ring that continuously releases an experimental antiretroviral drug in the vagina safely provided a modest level of protection against HIV infection in women, a large clinical trial in four sub-Saharan African countries has found. The ring reduced the risk of HIV infection by 27 percent in the study population overall and by 61 percent among women ages 25 years and older, who used the ring most consistently.
