I'm not sure what Swerd was getting at and I didn't read the article, but polls have shown partisan differences with regards to vaccine intent (e.g. article at link below). People's views on vaccines seem to be quite fluid, so it's not clear what the percentages will be in a few months. My best guess is that in a few months almost everyone except the hard core anti-vaxers will want the jab.
My impression is that there are a certain number of people who basically will not believe something unless they see it with their own eyes (so to speak). They don't take the virus seriously until someone they know gets seriously ill from it, and they won't trust the vaccine until after people they know get the jab without problems. This is just a hypothosis, I can't prove it.
I do not follow the anti-vaxer movement in any detail because it seems like a waste of time, but the big issue appears to be the (often disproven) belief that vaccines cause autism in children. Why this carries over to opposition to the COVID vaccine is a mystery to me. Do they believe adults will become autistic after getting a COVID vaccine? (that's a rhetorical question, I'm sure I could find the nutty answers doing a couple google searches)(I feel that reading wacky anti-vaxer stuff lowers my IQ because it renders me capable of imagining something that was too stupid to conceive of previously)
>>>Partisan differences, which have long characterized views about the outbreak, are increasingly seen in vaccine intent. Democrats are now 27 percentage points more likely than Republicans to say they plan to get, or have already received, a coronavirus vaccine (83% to 56%). This gap is wider than those seen at multiple points in 2020.<<<
77% think vaccinations will benefit the economy.
