I've also trusted doctors and medicine in the past and had a horrible outcome. If I had known ahead of time what would happen, I'd have killed myself first. It fucking ruined my life and messed up my brain. Although this happened several years ago and things have improved quite a bit, I'll never fully recover.
Even though it isn't really logical, I will never really trust healthcare again.
My plan is to get the COVID vaccine after first responders, teachers, people in health care, and perhaps even politicians receive it. If there are not significant problems reported after a month or two, then I'll get the vaccine. Any reasonable society would vaccinate those people first anyway.
