While numbers here keep dropping rapid ( just 1 dead today ) then the share of the British mutation are on the up, and now account for 20% of all positive tests
I don't think that matters, it has been shown that the British mutation spreads a little easier (1.35x), so it is inevitable that it will be the last to disappear, so you should expect the % British to increase as you get near to zero cases.
I am afraid some of these vaccinations are tailored too pressie and so don't take much in the way of mutation before they are useless.
It has been shown that the British variant has exactly the same symptoms and hospitalisation rates as the normal variant, it is no more dangerous, and the AZ vaccine does appear to 100% prevent hospitalisation with normal, British, and South African variants.
Also, it doesn't appear that you are any more likely to catch the British variant after already having had the original than you are to catch the original again, about 0.7% of people so far have had it twice, the second time with only minor symptoms or asymptomatic.
What bother me the most is the cold weather hovering between a couple of degrees frost to -10 degrees, and with no sign of that letting up anytime soon.
Yes, it would be nice if it warmed up, but your cold has arrived here today, was 14°C a few days ago, tomorrow is forecast for 1°C!
However light levels are increasing fast now, which should be helping the virus disappear in northern areas, make sure you get outside for a while, even if it is not exactly sunny.
