RNA vaccines work in a different way to conventional vaccines.
Using ‘messenger RNA’ = mRNA, they introduce an instruction messenger into the body. This contains the genetic instructions for your own cells to produce the relevant antibody and therefore generate an immune response.
This skips the need for you to become infected, for your immune cells to find the virus, process it, and present the viral antigens to your immune system to create the antibodies.
