The most common valid reason for people to be hesitant is that they have to take an action that might have negative consequences, even if the risk of taking action is infinitive small compared to not taking action. This is as illogical as a fear of heights, but that fear can be overpowering. It took me a lot of effort to climb even a lookout tower on a recent hike.This was the pfizer document, thanks for the source OG document. But those are the numbers that pfizer has that indicate 601 / 43000 had BC1 / BC2 higher level anaphylaxis compared to the earlier quoted 2-5 out of a million for other vaccines. Perhaps it's why some of the people here are hesitant
When I got my first set of batteries from Alibaba, I spend over a week top ballancing them, fearing that I would damage them if I didn't. After gaining some experience and reading other people's experiences here, I just put the batteries in parallel overnight before hooking them up to my solar panels and let the BMS do the balancing. Without the encouragement of Will's video's and many others here, I would never have taken those first steps.
All the evidence point to the vaccines being safe, just like the lookout tower is safe. Arguing that the tower, which is inspected by engineers on a yearly basis, might fall over is not a rational argument. I can assure you that the sense of fear is very real, but you don't see me arguing against climbing lookout towers, that would help no one.
