When humans develop immunity to a virus, they develop antibodies to that virus which usually attach to the outer surface of a virus and prevent it from entering the human cells. New strains of the virusIn analysing the Covid-19 virus, the initial virus which started spreading in Wuhan is not what’s predominantly spreading globally currently. In this mutation, the changes have been on the spike protein on the virus, which the Covid-19 vaccines target. The virus mutation potential increases with the increase in frequency of human and animal infections, thus stemming the infection of the virus is extremely important in limiting the number of new mutations occurring in Covid-19. The question arises whether the Covid-19 virus can further evolve.
