The Covid-19 vaccine created by Pfizer (PFE) and BioNTech(BNTX) uses a new technology called mRNA which stands for message RNA. But what are RNA vaccines and how do they work? The following is a fantastic infographic from Compound Interest that explain the details.
Here is how the CDC defines mRNA vaccines:
New Approach to 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. Instead, they teach our cells how to make a protein—or even just a piece of a protein—that triggers an immune response inside our bodies. That immune response, which produces antibodies, is what protects us from getting infected if the real virus enters our bodies.
