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
