COVID-19

What is COVID-19? COVID-19 (coronavirus disease 2019) is a contagious disease caused by the virus SARS-CoV-2, which most often causes respiratory symptoms that can feel much like a cold, the flu, or pneumonia. You can protect yourself and others by getting the COVID-19 vaccine. COVID-19 vaccine recommendations are based on age, time since the last dose, and, in some cases, the first vaccine received. People who are moderately or severely immunocompromised have specific recommendations for the COVID-19 vaccine.
