Trump doesn’t expect people to take what he says literally. That is a big problem. The Covid vaccine is dangerous, but all vaccines are not comparably dangerous. RFK opposes ALL VACCINES.
It is dangerous to make rash generalizations either in support of someone or against someone because you will be held to those opinions. Trump does that too often.
He has talked several times already about wanting safety tested vaccines (when asked) not doing away with them entirely and no one is freaking out but the media. I don’t see it as a make or break issue at this point. You can quibble with the spin Kennedy puts on a particularly study but at least he does make an effort to cite relevant work from PubMed or the National Library of Medicine.
