Sir David King told Sky News: "[There are] 5,300 new cases of the disease per day in the United Kingdom and we're up about 2,000 on last week.
"Now we've been discussing whether or not we're going into a serious third wave and I don't think we can possibly wait any longer. This is the evidence of another wave appearing."...
He said: "We know that anyone vaccinated twice is relatively safe against the virus.
"But let's not forget one in 25 new cases are people who have been vaccinated twice - that means 400 new cases a day are people who had the vaccine twice."
