WHO-UNAIDS brief on pre-exposure prophylaxis (PrEP)

This brief is intended as an introduction to HIV pre‐exposure prophylaxis (PrEP) for WHO and UNAIDS country and regional staff. If PrEP is shown to be effective in randomised controlled trials, countries need to be prepared to consider whether or not to include PrEP as part of combination prevention (behavioural, biomedical, and structural strategies). This document provides staff with the latest developments so they can brief stakeholders at country level on the progress of PrEPresearch and start discussions on the topic.
