Myocarditis in children after jab

A recent prospective study done in Thailand on the effect of the "vaccine" on the heart muscle on about 301 children, aged 12 to 18 revealed that 1 child in 300 had subclinical Myocarditis.
The children were followed up for 7days, 14 days and one month.
About 2 children had raised blood pressure.
The finding of 1 child in 300 had subclinical Myocarditis is high. It would mean 3.3/1000; 333/100000;
3333/1million. If 5 million children were jabbed it would mean 15,555 children would end up with subclinical Myocarditis.
This is a huge number. Unless trop T, CKMB, EKG, ECHO cardiograms are done, all these children would go unnoticed. The risk of not diagnosing it could result in sudden cardiac deaths due to arrhythmias caused by inflammation of the heart muscle.
The question that begs to be asked is: why jab children for a condition that has a 100% recovery rate with no complications. The regulatory authorities like CDC, FDA and WHO should have done their own studies make this finding and warn the public about the dangers of this jab. Better still, they should have stopped these jabs from being used at all.
All those in favour of these jabs must be held accountable.
