ABOUT MRNA VACCINES

(Pfizer & Moderna)

• Your body naturally uses mRNA to send instructions when building proteins.

• mRNA technology is new in vaccine production but is already being used in cancer treatment.

• It has been studied for more than ten years.

• The COVID-19 mRNA vaccines give instructions to our cells to make a harmless piece that looks like the “spike protein” on the surface of the COVID-19 virus.

• Our immune system sees these fake spike proteins and builds antibodies that recognize them. In the future our immune system will now recognize when the COVID -19 virus enters the body and can fight it.
