Figure 1O/E ratios of myocarditis and pericarditis in the first 1–7 days of receipt of any dose of COVID-19 mRNA vaccine by age group and sex in three large health plan databases
从这张图看,竖直虚线表示与以往发病率一致,没有变化。竖直虚线右边表示发病率增加。根据横线下标数字,疫苗注射后,总体发病率与以往发病率的比值约为2 ,也就是增加1倍。
他们的数据来源是 Optum, HealthCore, Blue Health Intelligence, and CVS Health,误诊可能性不大。总之,我认为疫苗后心肌炎发病率上升的结论是可靠的,但总体发病率仍很低。
另一个法国的研究发现情况更为严重,疫苗后心肌炎发病率增加更多,见:Age and sex-specific risks of myocarditis and pericarditis following Covid-19 messenger RNA vaccines, https://www.nature.com/articles/s41467-022-31401-5
