Can a COVID-19 vaccine make me sick with COVID-19?
No. None of the authorized and recommended COVID-19 vaccines or COVID-19 vaccines currently in development in the United States contain the live virus that causes COVID-19. This means that a COVID-19 vaccine cannot make you sick with COVID-19.
After getting a COVID-19 vaccine, will I test positive for COVID-19 on a viral test?
No. Neither the recently authorized and recommended vaccines nor the other COVID-19 vaccines currently in clinical trials in the United States can cause you to test positive on viral tests, which are used to see if you have a current infection.
If I have already had COVID-19 and recovered, do I still need to get vaccinated with a COVID-19 vaccine?
Yes. Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, vaccine should be offered to you regardless of whether you already had COVID-19 infection. CDC is providing recommendations to federal, state, and local governments about who should be vaccinated first.
Will a COVID-19 vaccination protect me from getting sick with COVID-19?
Yes. COVID-19 vaccination works by teaching your immune system how to recognize and fight the virus that causes COVID-19, and this protects you from getting sick with COVID-19.
Will a COVID-19 vaccine alter my DNA?
No. COVID-19 mRNA vaccines do not change or interact with your DNA in any way.
