@Weaver, the press such as BBC is full of speculation about a second wave of infections.
In fact the original Imperial College proposals for lockdowns was that the measures would be repeatedly turned up, and turned down, via on/off triggers, until full public vaccination is possible. The triggers would be in response to changing conditions. In other words, forget about the second wave, there will be multiple waves one after the other, hopefully no bigger than we’ve seen so far.
There will of course be a degree of hysteresis between the on switches and the off switches. So at times, infection rates will be high, with people still allowed to do things. Then an off switch be triggered, but only after new outbreaks emerge, and we’ll lock down again until it subsides.
I think that’s why they are now saying “stay alert”. If the next year or two does follow that pattern, do you really want to be encouraging visitors to visit your community?
