The article mentioned that the vaccine side effect risk was low. How is that quantified? Who knows?
However, the point of the article seems focused on the kids you were saying didn't need the vaccine who got The COVID and are now having heart attacks out of nowhere.
Don't know how it was quantified, honestly. It was put out as an emergency risk exemption or whatever. I'm guessing risk analysis was lacking, but they were basing it on data from previous RNA based vaccines.
As far as kids having heart attacks, I don't really know. Was it Covid or the vaccine? Or something else. I haven't really researched it. Basically, the way I see it, someone on Twitter posts something that says, "hey, this kid has a shitty heart because of the vaccine", it goes viral, then fact turns into fiction and fiction turns into fact, and at the end of the day nobody knows shit.
