Splet22. jul. 2024 · The most effective and the simplest way to prevent the increase in the number of variants is to reduce the opportunity the virus has for mutation. Vaccination does this by blocking it from replicating in our cells. By decreasing the rate of infection (and therefore replication), there are less opportunities for it to mutate.
