This is a problem with our notion of "expertise". We rely too much on them and delegate everything in our society to them. But first, there are varying degree of quality among experts. The delta is huge. Secondly, they are only human, and make mistake all the time. Thirdly, they have an agenda too. It may not be to help you the best they can, but to make a living with the least problem possible. Now another problem is that a lot of people reject expertise in a such a way that any honest attempt will look terrible after them. The typical anti-vaxer speech has no credibility at all, preventing any sane debate on vaccines. The pro consider it "not even a question". But everybody should always raise questions about any medical act before deciding to got for it or not. This include vaccines, band aids, whatever. The notion or "expert" also tends to remove responsibility from the people. But your health is YOUR concern, you choose take great responsibility in it. In the end, we should all learn to not ask experts to solve our problems, but to use them so we can solve our problems.
