The Coronavirus Variants: What You Need to Know

(Axios) – The big picture: Viruses mutate, often without impacting the severity of disease or how the virus spreads. But sometimes mutations are consequential for public health and scientists say it’s important to monitor them. Both Pfizer and Moderna are in the process of testing their vaccines against the variants. Pfizer and BioNTech said Thursday the mutation N501Y found in both variants B.1.1.7 and 501.V2 was tested against their vaccine and found “no reduction in neutralization activity against the virus.” But there are multiple mutations and more studies are underway.
