What is a COVID-19 variant, and will the vaccine protect me from it?
Viruses constantly change through mutation, and new variants of a virus are expected to occur over time. Multiple variants of the virus that causes COVID-19 have been documented in the United States and globally during this pandemic. Information about the characteristics of these variants is rapidly emerging. At this time, there is no evidence that these variants can evade the recently developed vaccines or cause more severe illness or increased risk of death.
