So mask wearing for at least another year then
Face masks could still be needed late into next year despite the rollout of the Pfizer vaccine, the UK government's chief scientific adviser has said.
"It's going to take quite a long time to make sure everybody in the at-risk groups - and all of the groups that are difficult to reach - get vaccinated as appropriate," he told Sky News.
He said it could take a month or longer before the vaccine gives full immunity.
"This is incredibly important and it is important that we all stick to the rules in the meantime. The rules are what's keeping the virus down now - we need to keep the virus down while we allow the vaccine programme to roll out," he said.
"It may be that next winter, even with vaccination, we need measures like masks in place - we don't know yet how good all the vaccines are going to be at preventing the transmission of the virus."
