I'm not sure of the exact requirements, but that is the next step from a pandemic.
We live with flu. It is easy to dismiss flu as a heavy cold, but it can be fatal. The flu jab is offered to certain sections of society, and i think that is the least we should be doing, as well as not carrying blithely on with our lives when we have it. (yes, asymptomatic people are a risk with any disease that may present like that)
So even if we're not technically at endemic stage, that's where we're heading and governments will follow their own paths towards how they handle it, hopefully using sensible unbiased medical advice.
Part of the problem that we have in developed democracies is our ability to question government decisions. And governing like policing is by consent: we agree to the rules for the most part but there are always some who laugh in the face of rules.
Unfortunately from where I'm watching, people in the UK seem to be very polarised around what has been going on, there doesn't seem to be much middle ground whether it's marmite, the PM or the rules around Covid-19. The MSM don't help there much, tbh.
And it's not that we don't have issues here in Germany, because oh boy we do.
