In medicine, any intervention has a risk to be balanced against the benefit. In the heat of the epidemic, I don't think there was any reasonable doubt that the benefit of the vaccine heavily outweighed the risk. Death rates in hospitals and care homes were witness to that.
As time has passed, it seems the risk/benefit equation is tilting towards risk. I have seen this in patients myself. I have decided against a booster this year (I routinely decline the flu jab for similar reasons). I got covid 2 weeks ago. Nasty laryngitis and a short lived fever. But nothing unusual compared to previous viral infections I always seem to pick up this time of year.
