Kind of. Basically nobody remembers how bad it was when polio and smallpox and whatnot were killing people so they think getting a shot is worse than the alternative.
That's one of the big issues I'm having with this, people do remember. Both Mitch McConnell and Neil Young have experiences directly related to polio, and that's just off the top of my head.
That being said the last iron lung polio survivor passed away this year. (Last one so far.)
I think the point was more that despite their personal experiences, they are still supporting this mindset. So even if it was more widespread, it wouldn't be preventing whatever is causing this "movement".
