I heard today the Pfizer vaccine has worse side effects than a flu vaccine. It is more like a shingles vaccine. There is some speculation after one such shot people will not want a second one, so people will be 50% not 95% protected.
My shingles shot was worse than any previous one I had, and I had decided I probably don't want another one but will take my chances.
So the prospect of a covid vaccine is not inviting. I would still get it if there is a "vaccine passport" I have heard some discussion of, and if said passport does not depend on having a smart phone since I don't, and if the passport would let me do everything I did pre-pandemic - travel, not wear a mask, etc. If I am undergoing a painful procedure twice I should have some rights that people who only get one shot or no shot at all don't have.
