The numerous mutations that the coronavirus has undergone since its classic version will make the vaccine not only annual, but now scientists are thinking of creating a vaccine with all the strains of the coronavirus that have emerged so far.

Viruses undergo constant mutations, and they number in the thousands, but according to the WHO only a few of them are considered important as they are threatening to public health.
