Yes once the most elderly and vulnerable are vaccinated we will can return to a moderated normal way of life.
I don't expect to be dancing in heaving nightclubs or travelling without a mask, but I do think many of the safer options like eating out, shops etc will be available again. Restrictions will still be in place in terms of mixing and face coverings. I expect that to ease into the autumn once all adults are vaccinated.
What is worrying me more are the chances of travel going back to what it is was. It is obvious to me that even if you are vaccinated, many countries will not be anywhere near it - and may still have lockdowns/overwhelmed hospitals as a result - therefore posing a danger and risk to anyone travelling there. Lockdowns have got faster, so travellers can end up stranded. New strains will keep breaking out, which will mean most countries may well decide to enforce and continue with total border closure along the lines of Australia and NZ. It is fast becoming apparent to me that we have a real global problem. Not with this strain, but all the others coming down the track every week.
I feel much less optimistic as result sadly. With one or two strains, that is fine - but wave after wave of mutations is a whole different ball game, and of course the worry that one of them will be far more deadly than this one.
I think we can open up as country, if we close the borders properly. We can have a decent standard of living too, if we do that, but what that means for aviation, travel etc....I don't know.
