An RNA or mRNA vaccines is based on special messenger molecules, the so-called ribonucleic acids (RNA). The injected messenger molecule contains the genetic code for a protein element against the coronavirus. After injection, the body will produce this protein element on its own and thus trigger a tailored immune response. This way, the immune system learns to produce antibodies that can attack the coronavirus immediately if an infection occurs, and they can keep it from reproducing in our bodies. After a short time, the injected RNA will be completely broken down by our bodies.
