Okay, explain this please (leaving aside Finley’s point that young people are the least likely to get covid in the first place).
Scenario 1: No jab, yes covid, yes cardiac symptoms.
So, you have symptomatic covid (because obviously asymptomatic covid doesn’t cause cardiac symptoms, since they’re… symptoms, after all), and it’s so symptomatic that it puts you at increased risk of myocarditis, cardiac arrest, etc. when you overexert yourself. Okay, do the cardiac symptoms come on suddenly, from zero to 911 in minutes? Or do you first have symptoms loud and clear enough that you know you’re sick and should stay home and rest (or get sent home if you go to your practice/game despite knowing better) instead of overexerting yourself?
Scenario 2: Yes jab, no covid, yes cardiac symptoms.
They tell you to stay for 15 minutes after the jab, just in case. You probably don’t have a practice/game scheduled for those 15 minutes. You probably don’t get cardiac symptoms in those 15 minutes either. Then you’re officially good to go, right? Say you have a game/practice within the next few days. You’re officially not supposed to worry, despite being at increased risk of cardiac symptoms. So now, compared to scenario 1, how fast do the cardiac symptoms come on?
Scenario 3: Yes jab, yes covid, yes cardiac symptoms.
If you have covid despite keeping your vaxport up to date, you probably have milder symptoms than you would without the jabs, so you are less likely to realize or even suspect that you have covid. Compared to scenarios 1 and 2, how fast do the cardiac symptoms come on?
