Researchers have discovered another new variant of the new crown virus in multiple countries

Researchers from the University of Edinburgh call this new variant of the new coronavirus B.1.525 and point out the spike sugar of this virus The protein has a mutation that allows it to bind to and enter human cells. Britain, Nigeria and 11 other countries have discovered this new mutant strain.

Scientists are worried, as this With the emergence of a mutation called E484K, the effectiveness of current vaccines against this new variant virus may be reduced. Researchers believe that the mutation will help the virus evade neutralizing antibodies. Simon Clarke, associate professor of cellular microbiology at the University of Reading, said that the E484K mutation does make South Africa’s new coronavirus mutant strain resistant to some vaccines.

Clark worries, new mutation assists It may also be resistant to current vaccines. Clark said that scientists do not yet know how effective the new mutant strain will be. However, if it spreads successfully, the immunity from any vaccine or previous infection will be reduced.

Medical experts do say that there is no evidence that new mutant strains will cause more serious diseases or increase the spread of new strains. As of this week, the UK has confirmed 46 cases of infection with the new mutant strain through genetic sequencing. In December of last year, Nigeria discovered the first case of infection with a new mutant strain.
