Also be a little wary of the ‘recorded side effects’. In the UK (and I’m sure its not alone), the NHS asked people to record any medical event that happened for a period post-vaccination that could conceivably be a side effect, in an abundance of caution - the idea that they could then sift the data for any actual side effects.
People often quote this raw data ‘look n people had heart attacks after vaccination’ - without factoring the expected number of heart attacks if that cohort had not been vaccinated. There’s some great stuff in the raw data like people who suffered twisted ankles. Reasonable to record, as say a statistically significant increase in twisted ankles could (say) suggest balance problems were a side effect (they aren’t)
In the US, this is often cited as “All-cause mortality”. Which means every tracked medication and procedure has a certain (extremely low) risk of car crashes, even in non-drivers.

Ah, a classic correlation is not causation situation. Thanks!
Not even that, more that the correlation might not be there in the first place.
