About Messenger RNA (mRNA) Vaccines
COVID-19 vaccine (Pfizer) is a messenger RNA (mRNA) vaccine.
mRNA vaccines teach cells how to make a harmless protein that is unique to the virus.
This harmless protein then triggers the immune response to produce antibodies that protect against the SARS-COV-2 virus, which may cause COVID-19 infection if it enters the body.
After our cells make copies of the protein, they destroy the mRNA from the vaccine.
