I have bad news for you (unless it was irony, which I can't rule out): the SARS-CoV2 virus contains its genome as RNA that is used directly (IIRC) as mRNA. Because it's needed for the protein synthesis to build new virus particles. This is true for every virus, BTW: they either contain RNA that can be used by the cell for protein synthesis (i.e. mRNA) or they do synthesize (or make the cell synthesize) the mRNA based on their genome, one way or another. So no matter what, you'll get the viral mRNA in your body. Either through infection or through the vaccine. The vaccine just contains a small fragment and it does not proliferate. Unlike the virus.
