Yea, too bad your shit study isn't even peer-reviewed and published yet, whereas my articles are peer-reviewed in NEJM and even published by CDC itself. Your article even admits that it's not peer-reviewed and should NOT be used to guide clinical practice.
From your article:
In , which has yet to be peer reviewed, Dr Tracy Høeg at the University of California and colleagues analysed adverse reactions to Covid vaccines in US children aged 12 to 17 during the first six months of 2021. They estimate the rate of myocarditis after two shots of Pfizer/BioNTech vaccine to be 162.2 cases per million for healthy boys aged 12 to 15 and 94 cases per million for healthy boys aged 16 to 17.
