I wonder though. I know someone under 40 who has complained of heart arrhythmia, sudden severe fatigue and a squeezing pressure on his chest. He had Moderna but it happened >7 days afterwards. He never reported it because he assumed it was psychological instead and that doctors would dismiss it with anti-depressants.

The paper doesn't give a rate for this type of thing, only for people who went to hospital. But if this is really one-in-a-million stuff I really wonder how I happen to know someone who has it. Also there are only ~21 million software developers in the world, HN has only a fraction of them reading let alone commenting and yet this thread is filling up with people describing the exact same thing that happened to my friend.

I find it hard to believe these things are really as rare as they're implying. Perhaps there's a reason they don't give rates for the "squeeze+tiredness+irregular heartbeat" problem.

Do we teach statistics in school anymore? This is such a nonsensical remark.

That's perfectly well-grounded. If a large chunk of your acquaintances were to be predisposed to something due to selection bias, you might be in similar groups and be predisposed to similar things.
