//I've still got some covid test kits - will they still be valid for any new variants?//
Why do you need to test yourself?
//Some folk are still classed as vulnerable so it makes sense to us.//
//Choux, indeed it [[wearing a face mask] does .//
Is it only Covid they are vulnerable to, or is it all infectious respiratory diseases? Leaving aside the issue that flimsy face coverings afford virtually no protection to either the wearer or those around them, if they are vulnerable to all such diseases, and you believe face coverings are of benefit, you should have always worn one, and continue to wear one so long as you are breathing.
//. . . so stand by usual spreaders and get ready to recommence your selfish activities.//
That is a statement of almost unbelievable ignorance and arrogance. The SARS-Cov-2 virus is now endemic across the world and will continue to be so for generations to come. We shall all be exposed to it multiple times in our lives, most of us already have been. I don’t know what “selfish activities” you are referring to, but if you mean having the effrontery to wander the streets without a flimsy face covering, you may like to study what good (or not) doing so does. Then, of course, there is nothing to prevent you from donning one, but you’ve no right to accuse those who decide to behave normally of being selfish. If you mean wanting to mix closely with other people, socialise and generally behave in a normal manner, you should realise that interaction with others is an intrinsic part of human behaviour. It is essential and not an optional activity that can be prohibited on the whim of foolish politicians.
The way the UK government dealt with the pandemic was nothing short of criminal. The after effects of Covid will be soon in the past for the vast majority of the population. But the after effects of the government's actions during it will be felt for generations to come.
