I don't think it has to do with facts so much as trust in institutions. Educated people I suggest are more likely to accept that the CDC's conclusions are reasonable, and then maybe do a quick Google search to confirm that. My vaxxine hesitant friends are those with no exposure to any kind of professional environment, and they believe all sorts of crazy things about what goes on within these groups. The problem is institutions made of people are fallible, and sometimes corrupt. But those failures take specific forms: usually a minority of people, possibly corruption over money, possibly over ideology etc.. But generally speaking the CDC is not made up of people who are actively trying to secretly hiding some big studies that show it's dangerous etc. - it'd be impossible as there are 180 nations and 10x that institutions dealing with all of this. There might be something to an 'elite arrogance' but I think it's more that it takes time for the information to come across to regular people. I'm highly doubtful that PhD's are more hesitant, but if they are, it would be very interesting to understand why.
