If my right hon. Friend will allow me, I am about to come to precisely the point he raises.
The second thing about omicron that I want to share is that, although we do not yet have a complete picture of its severity, even if its severity is significantly lower, the much higher transmissibility of omicron means that it still has the potential to overwhelm the NHS. Let us take the current observed doubling time of two years—[Interruption.] Sorry. Let us take the current doubling time of two days. If, for argument’s sake, omicron is only half as severe as delta, after the lag between cases and hospitalisations has taken effect, that would buy us only two days before omicron hospitalisations reach the same level as for delta.
