Public Health England have launched the world's largest PrEP study.

Treatment and monitoring is free of charge. The study will run for three years.

We have already included our allocated number of men who have sex with men and transgender women. However we still have places available for people with partners who are HIV+ and don't have an undetectable viral load, and other people at similar risk of infection. In particular we have been asked to find people who may be at risk of acquiring HIV through heterosexual sex (sex between men and women). This includes people who may plan to travel to countries where HIV is more common and have sex whilst they are there.

People taking part will have the option of taking the treatment either every day or when the risk of infection is greatest (Event-based dosing).
