Myth: Coronavirus vaccines alter DNA
Fact: The coronavirus vaccines developed by Pfizer-BioNTech and Moderna contain messenger RNA (or mRNA) which instruct our cells how to make a protein that triggers an immune response. This builds immunity against the virus that causes Covid.
The mRNA (i.e., the instructions) from a Covid vaccine never enters the nucleus of the cell, which is where our DNA is kept, the U.S. Centers for Disease Control and Prevention says.
“This means the mRNA cannot affect or interact with our DNA in any way. Instead, Covid-19 mRNA vaccines work with the body’s natural defenses to safely develop immunity to disease.” In addition, immune cells break down and get rid of the mRNA soon after they have finished using the instructions.
