Yes, absolutely the right decision. Other home countries have increased restrictions - and yet cases are rising. People aren't dying any more than with 'flu (and there is a nasty variant about which 2 people I know have caught). I don't know about other countries - been switched-off for Christmas, rather nice.
We're just fed-up of it and would rather we all took our chances - the vast majority of the population is vaccinated and the ones that aren't - won't be. You can never achieve 100% and I can understand the point that is 'Why?'; lockdowns still happen even if you are vaccinated - and you can still catch it and pass it on.
