mRNA vaccines are not really new [0]. This article [1] specifically shows that we've used the mechanisms of mRNA vaccines since the 70s, and at least modern iterations of mRNA vaccines since ~10 years ago. Even if they were new, they're just a bunch of the same sort of genetic material that is already floating around in our bodies, not some external foreign substance that interacts with our cells.
