mRNA Vaccines are a new kind of vaccine that use a special type of molecule, called mRNA, to help your body fight an illness. mRNA stands for messenger ribonucleic acid, and it’s like a special code that teaches your cells how to fight a certain disease. When you get an mRNA vaccine, your cells use the mRNA to make proteins that look like the germ that makes you sick. Your body recognizes these proteins as foreign and starts making special proteins called antibodies that help fight the disease. So, your body is now ready to fight the disease if you ever get exposed to it. This means that mRNA vaccines protect you from illnesses and help you stay healthy!
