Study: PrEP for High-Risk Gay Men Possibly Cost Effective

Even if pre-exposure prophylaxsis (PrEP) only prevented one in two HIV cases and were taken only half the time, it would keep HIV prevalence at current levels among gay men with high-risk behaviors and prevent as much as a 5 percent prevalence increase, according to an Australian study reported by aidsmap.  

The mathematical analysis found that continuous PrEP would be barely cost effective, even though it would significantly lower prevalence among high-risk gay men. Intermittent PrEP could be more cost effective, but it would need to be at least 90 percent effective, which is a higher efficacy rate than it has currently demonstrated.  

According to the article, PrEP would not be cost effective for heterosexuals or gay men without high-risk behaviors. The continuous PrEP scenario would cost $330 million per year with a minimum cost of $35,000 per individual annually.
