The mutation is inevitable. There are more and more variants of the coronavirus. What will its further evolution lead to? Mutation of the virus: how new variants appear With each reproduction small copying errors occur, and these errors change the genetic code of the virus. Thus it is constantly mutating. This is normal. Some mutations make the virus more resistant to the vaccine; some, on the contrary, weaken it. Often they have no effect at all. But in the process of virus evolution, the strongest variant wins. In the case of the coronavirus, this means that variants that are more contagious, particularly delta, crowd out the less dangerous forms. There are becoming so many that new variants of SARS-CoV-2 will be called names of constellations - the Greek letters may run out of. The total number of mutations that have been identified in the sequenced genomes of the SARS-CoV-2 virus collectively amounts to many thousands
