There's evidence of at least seven U.S. variants of the coronavirus, while another that emerged from the U.K. is poised to become the dominant strain here by the end of March. One adviser from the Food and Drug Administration tells NPR there's a tipping point to watch for: when a fully vaccinated person winds up hospitalized with a coronavirus variant.
NPR science correspondent Richard Harris reports on concerns that COVID-19 vaccines themselves could cause the virus to mutate.
