The Pre-Exposure Prophylaxis (PrEP) ring, also known as the dapivirine ring, can reduce HIV infection in women by 50% if rigorously adhered to, according to the New HIV Vaccine and Microbicide Advocacy Society (NHVMAS).
PrEP is a medication that people who are at risk of catching HIV through intercourse or injecting drugs take to avoid doing so.
When used as directed, PrEP is very successful at preventing HIV, lowering the risk of transmission from sex by roughly 98%.
When worn with high adherence, the dapivirine ring, could cut the prevalence of HIV among women by 50%.
Women can put on or take off the PrEP ring on their own, without assistance from a medical professional.
