It is the same old story, it is about hospital capacity.
If hospitalisations stay low enough, another lockdown won’t be necessary. If hospitalisations rise, we will be locked down again and people will ‘give a fuck’, as they will firstly be encourage to and, if that does not work, will be made to.
At the moment vaccines do seem to work (thank god). The report was relatively optimistic about this, saying that, even first dose efficacy was only lowered by 15-20%.
If we vaccinate quickly, we will hopefully be ok here.
It is very depressing, though. But, we will win the war, our victory may just be delayed.
