Myopericarditis following COVID-19 mRNA vaccination
"In new preprint, researchers from Kaiser Permanente in Oregon show how rates of post-vaccine myocarditis may be underestimated by just using ICD10 diagnosis codes currently used by VSD (the official surveillance network).
"We identified that the encounter text description methodology identified approximately twice as many cases of myopericarditis following COVID-19 mRNA vaccination."
For males following the 2nd dose the rate was found to be 537.1 per million or 1-in-1,862.
