I don’t have a particular dog in this fight, but your comment: “But they can also cause some severe problems, per the literature that the manufacturers include with the doses” is the old correlation versus conservation confusion. If something has happened when the vaccine was being taken or shortly thereafter, it is included in that list. We don’t know if the vaccine had anything to do with the condition. You have to look at the numbers for the clearest picture.
The vaccine pamphlets (there’s a name for them my brain can’t remember right now) provided by the manufacturers list several neurologic diseases that can be caused by their vaccines, such as guillanè barr syndrome. I’m aware of the whole correlation/causation issue. If the manufacturers are admitting that it happens, albeit rare, it probably really does happen. I have no reason to think they would disclose this info and it not be possible.
I don’t care one way or the other if people vaccinate, I think that is their own decision to make. But, it would be fantastic if everyone had access to clear, concise and mostly correct information. Vax advocates want you to think that absoluteky no harm could ever come from vax and anti- vaxxers want you to think they’ll kill you just by looking at them.
