Here's my vision for the future
1. Lots of sickness and death in Europe and the USA, due to the ravages of δ. We will be OK in the UK because vaccination and exiting from the current lockdown has been well managed.
2. It'll be like gastroenteritis. Nearly everyone catches it often, most people shake it off, a few people end up in hospital and a few people have a long form -- IBS. We're all taught how to take precautions against it, and no-one lets it get in the way of having fun unless they've got some sort of aggravating medical condition or they're neurotic.
3. Domestic life mostly back to normal, as if nothing ever happened, in the UK in 2023 or even earlier. There will be lots of test, trace, isolate to guard against new variants and rapid vaccination against them.
4. In Europe there may be a reaction against the EU, demands to leave à la Brexit. Vaccine reluctance will be all but eradicated for adults.
