You should get a COVID-19 vaccine even if you already had COVID-19.
Getting a COVID-19 vaccine after you recover from COVID-19 infection provides added protection to your immune system. People who already had COVID-19 and do not get vaccinated after their recovery are more likely to get COVID-19 again than those who get vaccinated after their recovery.
All COVID-19 vaccines currently available in the United States are effective at preventing COVID-19. Getting a COVID-19 vaccine gives most people a high level of protection against COVID-19, even in people who have already been sick with COVID-19.
