What is PrEP, the drug which prevents HIV infection?
The drug which is going to be available through the NHS in Scotland is known as PrEP, short for "pre-exposure prophylaxis". It's intended for healthy people who are high risk of getting HIV, for example men who have unsafe sex with multiple male partners. The NHS in England is having to consider prescribing the drug, but many people buy it privately.
