Technology highlight

The ring is made of a flexible silicone polymer and contains the ARV dapivirine, an NNRTI, which is dispersed in the silicone matrix and slowly released over the course of a month. The ring delivers dapivirine directly at the site of potential HIV infection, with low systemic absorption. Women insert the flexible, long-acting ring themselves into the vagina and replace it every month.
