What is a COVID-19 Variant?

Viruses constantly change, creating new strains (or variants) over time. These variants are slightly different from the past strains and can infect people who had COVID-19 before. Some variants cause more severe illness, especially among those who are younger. Vaccination is the safest way to protect yourself and our communities against the variants. #CommunityImmunityWV
