I'm not entirely sure what went into my decision to get the vaccine (and then the booster). I don't think it was really down to a highly-technical, fully-informed, cost/benefit analysis, based strictly on peer-reviewed research in high-quality journals. It feels like elements of socialisation and group-identity went into it as well. I just trust one side a lot more than the other (indeed, 'the other' seem outright crazy, to me).
I even had some doubts about the booster, on the basis that it seems I might have an auto-immune disease (something that came out after I had the initial two jabs), and until I get to see the consultant to discuss it I am a little nervous a vaccine might exacerbate that (the health system having ground to a halt that hadn't happened by the time of my scheduled booster jab). But in the end I concluded I'm more worried about getting COVID and suffering long-term consequences, or, worse, passing it on to elderly relatives, so decided to just get it over with and ask the consultant about it retrospectively. But that's as much a social-political judgement as a technical one, I think.
I find it very hard to separate intellectual 'knowledge' from things to do with identity and politics. I mean the two are statistically correlated, as level-of-education correlates with voting patterns, for example. And maybe it depends on how one feels about individual risks vs collective benefits, which is a political question.
