Foreign mRNA doesn't hurt us because it's recognized by the body as harmful and immediately destroyed by the immune system. This was one of the biggest challenges to developing mRNA based drugs and vaccines. The mRNA used in the COVID shots isn't normal, of the type found in the wild. It's been created in such a way that the immune system doesn't recognize it, and then wrapped in artificial lipids. So you can't generalize from natural mRNA molecules to the artificial types, they are fundamentally different in both construction and effect.
