A lot of gloomy predictions!
I think more than one vaccine will be up and running, & Mumsnet will be full of discussions on which to have early next year.
I think frontline workers and the vulnerable will have had jabs by this time next year, though the government will manage to inexplicably leave out one vulnerable group from the first wave of vaccines, because that’s what they do with everything.
By this time next year, people who want a jab will probably have got one, but there’ll be a bit of outrage when some people not wanting vaccines are then not allowed to travel to other countries until they have. Many people will be campaigning for the government to hurry up in getting on with the international programme to get vaccines to less wealthy countries.
I think more people will continue to work from home at least part-time if possible, people will tend to distance slightly more, and managers will encourage staff with contagious illnesses to stay off work, by paying sick pay. People might even wear masks if they have colds, so annual flu/cold figures will drop massively.
There will be a move away from cities- homes with gardens will become more expensive.
The economy will be pretty grim, the government will be grumbled about for doing nothing. Boris Johnson will resign and go and write books or something, and his successor will struggle almost as much. We’ll make more use of open air spaces, and schools by then will have more funding for digital provision. Coursework will be back, by popular demand from parents, and university admission will change to January each year, so that finalised grades can be part of the process, and new undergraduates have a chance to work and save money before the first term.
