Regarding covid vaccine and DNA, the main problem isn't with the vaccine itself, but rather with certain lots being contaminated with plasmid DNA. So a QC problem, not necessarily a mRNA vaccine technology problem.
Of course it's all just a crazy conspiracy theory propagated by those insane MAGAs...... and PubMed.
