You have no evidence either way about his example. People have died from adverse effects from them. That's just a fact.
It's a "factoid", in that it conveys a misleading
impression to the unaware.
Another fact:
People have died from drinking water.
Does this mean water should be avoided?
Of course not.
You're far more likely to die from Covid 19
than from vaccination.
For example:
Lisa Shaw: Presenter's death due to complications of Covid vaccine
And that's the BBC, not some "conspiracy" site. Maybe the people he knew got the AZ shot.
The informed analyst will compare hospitalization
& death rates from Covid 19 for vaxed & unvaxed.
One should not take 1 data point, & present that
as the total reality.
Someone I know (Katy) died from complications of
heart surgery. But I also know Gus, who is alive
& healthy today only because he had heart surgery.
So the issue is about the likelihood of successful
outcome.....not focusing upon solely the worst
outcome of only 1 alternative.
