J&J has DNA in it, I've read it goes directly to the cell nucleus to make mRNA, which then goes out to ribosomes in cytoplasm to make the spike. That DNA hanging around in the nucleus could get incorporated in the host DNA (don't know the exact molecular biology and chances that is does, but I'm sure there's a chance it does...). Vax's with mRNA goes to the ribosomes (and maybe to nucleus, and could get put into DNA if reverse transcriptase is around). It's a soup of synthetic bad news.
