An interesting survey by Carnegie:

Here are the parts that catch attention:
To translate from statistics to English, this turns the idea that people hesitant in regards to vaccinations *or* people who outright refuse to take them are "uneducated" upside down. It appears that the group that is hardest to convince is in fact the group with the highest educational success, PhD's. Sorted by education, their hesitancy is the highest. My guess, to paint with broad strokes, is that they're a group of people who think they're "too smart" to get sick - smarter than the experts. It's hubris. The people in the middle, with moderate educational attunement, are easily convinced.
In addition, large swathes of people refuse to take the vaccine on political grounds entirely. They're not concerned about the actual side effects, only the moderates are. You can't convince a person like that, it's a waste of time.
This makes perfect sense to me - people who have achieved success in the realm of education tend to consider themselves the smartest person in the room regardless of qualifications in a given subject matter. More broadly, people tend to tow the party line, so they'll obviously show dissent if the issue continues to be politicised. Nothing new under the sun for the observant among us, but it confirms suspicions with some numbers.
Oh joy, another non-peer reviewed paper with dubious headlines from Foxy... you really ought to wait for some meaningful numbers before making speeches and proclamations.
