About Messenger RNA (mRNA) Vaccines

mRNA vaccines teach cells how to make a spike protein that is unique to the SARS-CoV-2 virus (the virus that causes COVID-19).

This protein then triggers an immune response to produce antibodies that protect against the SARS-CoV-2 virus.

After cells make copies of the protein, the vaccine mRNA is broken down and removed from the body.

mRNA never enters the nucleus of the cell, which is where DNA is kept.

mRNA vaccines:

• Do not change or interact with the recipient's DNA in any way
• Do not use the live SARS-CoV-2 virus
• Cannot give the recipient COVID-19
