Myth: COVID-19 vaccines authorized for use in the United States will shed or release their components.
Fact: Vaccine shedding can only occur when a vaccine contains a weakened version of the virus. None of the vaccines authorized for use in the U.S. contain a live virus.

Myth: It is not safe for me to get a COVID-19 vaccine if I would like to have a baby one day.
Fact: There is currently no evidence that COVID-19 vaccination causes any problems with pregnancy, including the development of the placenta. In addition, there is no evidence that female or male fertility problems are a side effect of any vaccine, including COVID-19 vaccines.

Myth: The COVID-19 vaccine will alter my DNA.
Fact: COVID-19 vaccines do not change or interact with your DNA in any way. Both mRNA and viral vector COVID-19 vaccines deliver instructions (genetic material) to our cells to start building protection against the virus that causes COVID-19.

Myth: Getting a COVID-19 vaccine cause me to test positive for COVID-19 on a viral test.
Fact: None of the authorized and recommended COVID-19 vaccines cause you to test positive on viral tests, which are used to see if you have a current infection.​

Myth: The COVID-19 vaccine will make me sick with COVID-19.
Fact: None of the authorized COVID-19 vaccines 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.

Myth: Researchers rushed the development of the COVID-19 vaccine, so its effectiveness and safety cannot be trusted.
Fact: Studies found that the two initial vaccines are both about 95% effective and reported no serious or life-threatening side effects. There are many reasons why the COVID-19 vaccines could be developed so quickly. Here are just a few:

  • Information was shared promptly, so scientists could start working on vaccines.
  • The vaccine developers did not skip any testing steps.
  • Vaccine projects had plenty of resources.
  • Because COVID-19 is so contagious and widespread, it did not take long to see if the vaccine worked for the study volunteers who were vaccinated.
