MYOC and myocarditis: To elucidate the characteristics of classical monocytes in patients with BNT162b2-MyoC in more detail, we performed comparative analysis with various datasets: single-cell RNA sequencing data of PBMCs from seven patients with COVID-19 and six healthy individuals (GSE150728) (2), CITE-sequencing data of PBMCs from six vaccinated individuals without side effects (GSE171964) (5), and single-cell RNA sequencing data of PBMCs from young patients with Kawasaki disease or COVID-19-induced myocarditis (CoV2-MyoC) (GSE167029) (11) (Figure 3A and Supplementary Figures 4A−C).
