Rep[orts of a new, much more contagious, covid variant - officially #B11259, it has come out of Africa. You know, the place where some people here said was not affected by covid, thus proving vaccines are pointless.
So, it seems that maybe vaccines were needed in Africa, as these mutations can only happen when the virus is left to rampage through the population.
"Senior scientists on Thursday evening described B.1.1.529 as the worst variant they had seen since the start of the pandemic. It has 32 mutations in the spike protein, the part of the virus that most vaccines use to prime the immune system against Covid. That is about double the number associated with the Delta variant. Mutations in the spike protein can affect the virus’s ability to infect cells and spread, but also make it harder for immune cells to attack the pathogen." https://www.theguardian.com/world/2021/nov/25/what-do-we-know-about-the-new-worst-ever-covid-variant
