A few others have pointed it out but there’s a critical misunderstanding that mRNA has the ability to affect DNA, which is does not.

It operates outside the nucleus providing instructions for the cell to create proteins. In the case of the Covid vax it created a specific protein from the virus in order to trigger an immune response, but none of this process touches DNA

None of this is to say there won’t be potential problems down the road, but mRNA doesn’t change your DNA and I feel like that’s a big point the public is stuck on
