Prevention  

COVID-19 vaccines are effective at protecting you from getting sick. Based on what we know about COVID-19 vaccines, people who have been fully vaccinated can do things that they had stopped doing because of the pandemic. Everyone aged 12 years and older should get a COVID-19 vaccination as soon as possible. They are widely accessible in the United States and are available for everyone at no cost. Learn more about how you can get a COVID-19 vaccine here.

If you are not vaccinated, the best way to prevent infection is to avoid being exposed to the virus that causes COVID-19. You can do this through social distancing and mask-wearing to reduce contact and therefore prevent the spread of the virus.
