We have to learn to live with Covid in it's various forms, it will be with us forever.

I made that point over year ago.
And it has always been my understanding that as long as the virus is around it will continue to mutate and find easier routes to infect - That is what one of the factors that drove Darwin to his conclusion about "Survival of the Species"
The only way to defeat the virus is to remove all possible routes for transmission, that's 100% isolation of the infected, and or 100% vaccination. And we will never achieve either, becasue there some block heads who do not or will not understand the way a virus works and they think their actions won't matter or affect others.
We currently are not vaccinating some groups for medical reasons, unfortunately those few if they do get infected are likely to have immune deficiencies that enable the virus to collect more DNA/RNA patterns and use them to make themselves more transmissible, and or more infectious.
I am sure we will get to a point where we can consider this virus to be no more life threatening than the common cold or influenza, but we are along way off as yet.
Whilst we may be able to control what happens in the UK,, there are millions more people beyond our borders who will remain at risk at producing a more virulent strain.
