Gay men who want to be promiscuous should use condoms to protect against AIDS and other stds. I don't see why someone choosing to have unprotected sex should have this drug paid for by the nhs. Is someone with a lifestyle chaotic enough to have unprotected sex with lots of partners likely to remember to take the pill every day? i feel that £420 per month is a lot to spend on a healthy person who chooses to indulge in risky behaviour.
If these anti vital drugs are used in healthy subjects is there a danger of complacency. I also think that the AIDS virus might mutate and become drug restistant like bacteria and antibiotics.
