Public Health England are launching the world's largest PrEP study.

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

It is open to men who have sex with men, transgender women, people with partners who are HIV+ and don't have an undetectable viral load, and other people at similar risk of infection.

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).
