Will receiving an mRNA COVID-19 vaccine cause changes to my DNA?

Receiving an mRNA COVID-19 vaccine will not cause any changes to your DNA. mRNA does not affect or interact with your DNA in any way. Instead, COVID-19 vaccines that use mRNA work with your body’s natural defenses to safely develop protection against COVID-19.*
