New research out of the University of Alabama at Birmingham has found an HIV prevention method for women is safe. The early phase one trial tested out new intravaginal rings carrying two anti-HIV drugs. Women who used the rings for a month found them acceptable and one of the drugs was detected later. Unfortunately, the other wasn’t. But Craig Hoesley, a doctor and professor of medicine who oversaw the trial, said the results were encouraging. He says other HIV prevention methods like condoms are useful.
