You don't know what you are talking about.Wrong.
The mRNA injections do not contain the virus or any virus parts.
They contain mRNA instructions for the ribosomes in our own cells, to start our own cells to start growing spike proteins.
And there are several problems with this strategy.
One is that the mRNA is so small it is not confined to the muscle injection site.
And depending on where it ends up, it has caused death or the need for amputation of hands or feet.
And additional means of death is that it has no quantity control, so can make so many spike proteins grow that you get a fatal autoimmune response.
