I think it's really important that people who are taking PrEP—of course, they shouldn't face any stigma, and of course we will ensure that that is the case. But the way to do this is to bring the public with us, and I am very, very keen to make sure that we raise public awareness of the fact that the world has moved on a huge amount since the 1980s, and people who receive that antiretroviral therapy can and do live long and healthy lives, and the viral load in their blood is reduced so significantly it means that they can't transmit it to their sexual partners. It's really important that that message gets across, and we mustn't be scared of saying that out loud.
