Mutations in viruses occur continually and though many don't result in changes in disease severity or immune response, COVID-19 has mutated in some ways that concern scientists. These variants apparently originated in the United Kingdom, Brazil, and South Africa, though recently scientists have found evidence of about seven variants in the U.S. How and where are these variants developing -- and how well is the U.S. tracking them compared with other countries?  How do current vaccines hold up against these variants and what work is being done now to prepare for new, potentially more virulent strains? We explore these questions and more.
