All fair points. I have met more than a few people who I wouldn't consider "poor", but certainly not the very progressive/elite/educated class, who didn't want to take the vaccine because they feared missing work. After it became more widely accepted and restrictions tightened, they did get it. I have known people who were in that class, who were simply "scared", those were their words. I have all three shots too, but I don't look at it as a class or intelligence signifier, in absolute terms, the way some people are guilty of. My Dad being one of them.
