This is the same Sir Patrick Vallance who was talking up herd immunity in the 2nd week of March last year, only to reverse that a week later and advise on a lockdown."In a recent interview chief scientific adviser Sir Patrick Vallance said: "The lesson is go earlier than you think you want to, go harder than you think you want to, and go a bit broader than you think you want to in terms of applying the restrictions.""
Shame Johnson didn't do it. But he did do 'everything possible'.
Johnson is certainly at fault for the delay over the Christmas/New Year period of delay in restrictions but it’s very clear he was advised that herd immunity was a good idea, at the very beginning, and the 2nd lockdown he was criticised for going toot early.
