The basic requirement is to get through this winter without people dying because the NHS is overwhelmed (and the death count, all causes, will be the very worst in those circumstances, as all services could come to an abrupt halt, and the risks of increased suicide and death by other causes will increase hugely)
There is no slack in the NHS in winter anyhow.
The hot summer days are definitely behind us. What everyone chooses to do now will shape what is needed in the coming weeks.
