Even if they use a viral vector they are most likely still using the lipid nanoparticle carrier and the n methyl pseudo uridine to make the inserted RNA last longer. Both of these were causing the problems in the mRNA covid vaxx.
It’s DNA not RNA. I see no reason that they would need to use substances developed for RNA when doing DNA gene therapy which has been around a lot longer and has nothing to do with the immune system or vaccination.
You sound a little nuts.
