Understanding mRNA COVID-19 Vaccines
mRNA vaccines are a new type of vaccine to protect against infectious diseases. To trigger an immune response, many vaccines put a weakened or inactivated germ into our bodies. Not mRNA vaccines.

That immune response, which produces antibodies, is what protects us from getting infected if the real virus enters our bodies.
