Heard about this in the UK today...
The father of this girl I know died, 2-3 days after getting the booster shot. The guy died of a heart attack and was found dead on the bathroom floor after falling off the the toilet seat. Mid 60's.
She gets a call before the funeral, and I'm not sure if it was from a doctor, but they asked her what she wanted the "Cause of death" to be on the death certificate for her father.
She lost her shit, basically asking why they're asking her for this info and not the result of an autopsy or doctors report, and didn't give any answer for them to put down.
Then, I hear from someone else I know that this phoning for cause of death happened to someone else that know too.
I'm wondering if there's a relationship between the call she got and the booster.
