COVID-19 Vaccine Safety ~ Myths & Facts

Many people are becoming eligible to receive the COVID-19 vaccine in Massachusetts. It is critical for all residents to have accurate vaccine information to be able to make an informed decision regarding their health.

Can a COVID-19 Vaccine make me sick with COVID-19?
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?
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?
You should be vaccinated regardless of whether you already had COVID-19. That’s because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19. Even if you have already recovered from COVID-19, it is possible—although rare—that you could be infected with the virus that causes COVID-19 again. Learn more about why getting vaccinated is a safer way to build protection than getting infected.

Will a COVID-19 vaccination protect me from getting sick with COVID-19?
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?
COVID-19 vaccines do not change or interact with your DNA in any way.

Is it safe for me to get a COVID-19 vaccine if I would like to have a baby one day?
If you are trying to become pregnant now or want to get pregnant in the future, you may receive a COVID-19 vaccine when one is available to you.
