In the USA, it's estimated that 115 million people will be travelling over Christmas. Fun at Christmas, funerals in January.
In the UK, vaccinations have started. Between 8th and 20th December, there were 521,594 jabs. 70% of them (346,715) went to over 80s, 30% to healthcare workers.
The new strain (Covid-19.b) is accounting for 2/3 of new infections in London, the Southeast and Eastern England. This new variant is some 56% more infectious
That means it spreads faster, of course, but it also means that the herd immunity percentage will be higher than the 60 or 70% for the original Covid. More like 80%.
But that's how evolution works, survival of the organisms that are most suited to their environment.
China has banned all UK flights. Oh, irony.
