Britain’s chief scientific adviser stoked controversy on Friday when he said that about 40m people in the UK could need to catch the coronavirus to build up “herd immunity” and prevent the disease coming back in the future.
“Communities will become immune to it and that’s going to be an important part of controlling this longer term,” he said. “About 60 per cent is the sort of figure you need to get herd immunity.”
In another interview with the BBC, Sir Patrick said: “If you suppress something very, very hard, when you release those measures it bounces back and it bounces back at the wrong time.”
He added: “Our aim is to try to reduce the peak, broaden the peak, not suppress it completely; also, because the vast majority of people get a mild illness, to build up some kind of herd immunity so more people are immune to this disease and we reduce the transmission, at the same time we protect those who are most vulnerable to it.”
