Restrictions will be lifted, bit by bit, over several months, when infection rates, and particularly deaths, fall enough, whether that's by vaccinations, herd immunity or mutations or whatever. Covid will always be with us, just as is norovorus, measels, chicken pox, etc.
We'll see a gradual removal of official restrictions/prohibitions, such as pub opening times, sports stadia numbers etc., together with society generally moving away from social distancing, masks, etc. A lot of the restrictions will just naturally disappear, such as masks - there'll never be an official announcement that masks are no longer needed, but society itself will start to stop using them, alongside the vulnerable/worried continuing to use them if they wish.
Big gatherings such as 50,000 in a football stadium or 10,000 at an indoor music festival, or crowded nightclubs, will be the last to officially be allowed to re-open as they're the highest risk areas.
Most people will be back to work long before then, hopefully as early as Easter, as when infection/death rates fall, there's no reason why workplaces can't return, with sensible precautions, such as handgel, etc.
People don't all need to be vaccinated - simply by other people being vaccinated, the spread will be much reduced and infection rates will fall. Within a few months, there'll be similar risk of catching covid in the shops/workplace as there is of catching norovirus or flu. That's an acceptable and balanced risk. Yes, some people will catch it, some may die, but that's the same as with other viruses - it's impossible to make life 100% safe for everyone.
I think, and hope, that this pandemic will leave a lasting legacy of everyone taking hygiene etc more seriously. More regular handwashing, more hand gel stations in shops and workplaces, more awareness of catching coughs/sneezes, more respect for personal space, no more "shaming" of people who choose to wear masks etc. More cleaning and hygiene in hospitals and care homes.
One thing for sure is that covid won't be the last pandemic. We have to hope that we ALL learn from this, at population level, employer level, and governmental level, and that we're better prepared for the next one that comes along, all of us.
