It is important to continue to wear your mask over your nose and mouth, practice social distancing (staying at least 6 feet apart), continue to frequently wash your hands or use hand sanitizer with at least 60% alcohol after getting vaccinated. You must get both doses to be fully vaccinated against COVID-19. Experts are still working to understand how much protection the COVID-19 vaccine provides. It is possible that some people who get vaccinated could still get sick and spread the disease to other people.
