Viruses mutate as they spread through a population, with some mutations impacting vaccine effectiveness, as well as the lethality and transmissibility of variants, 据CDC称.

World Health Organization said Monday that BA.2 differs from the original omicron strain on the spike protein, emphasizing that the two subvariants should be studied independently to determineimmune escape properties and virulence.
