WTH does “ causally connected” mean?
It means 28 were all vaxxed and they all dies of myocarditis.
That the vaccine shots caused the deaths.
More precisely if they had not had the jabs they would not have died excepting if not having the jabs set up a chain of events that had them dying in some other way (for example suppose that having not gotten the jab somebody happened to drive home a little earlier and it just so happened that this meant they were in a particular intersection that a drunk driver came speeding through or some such).
