HIV discoverer: 'To develop a cure is almost impossible'

A cure for me is almost an impossible mission because the reservoir of cells is not only in the blood. How to eliminate all the cells which are reservoirs is why I say it’s an impossible mission. They are everywhere — in the gut, in the brain, in all the lymphoid tissue.

Even if you have a very efficient strategy, how you can make sure that there’s not one or two cells still there and if one is there the virus will reappear again? That’s why I say it’s an impossible mission.

But you never know.
