WORRISOME: infections in the UK soar with mutant #coronavirus strain B.1.1.7 that appears to spread more easily between people.
#B117 strain acquired 17 mutations *all at once* (including 8 in the spike protein gene)
never seen before in this virus. 1/https://www.sciencemag.org/news/2020/12/mutant-coronavirus-united-kingdom-sets-alarms-its-importance-remains-unclear …

GOOD NEWS: the
@WHO says the#coronavirus vaccine should still work against this new variant spreading quickly in the UK. The B.1.1.7 variant may be more transmissible, but there's no evidence it increases the “severity associated with this disease.”

It's NOT the first time the #coronavirus mutated. As more people become immune—via infection or a#vaccine—the virus is under selective pressure to evade the immune response. This could become like flu, where we have to update our vaccine each year.https://twitter.com/DrDenaGrayson/status/1308843921586483202?s=20 …Dena Grayson, MD, PhD added,

BREAKING: Massive study of more than 5,000 genetic sequences of the #coronavirus reveals continual viral mutations—one mutation in the gene encoding its spike protein may have made the virus MORE CONTAGIOUS.

Not likely, at least not to the point of needing *yearly* reformulation of the vaccine. #SARSCoV2 has a much lower mutation rate than influenza viruses.
