Through mid-March, 2022, the number of fatal myocarditis or pericarditis cases after covid-19 vaccination totaled 122 (=~0.78% of the total ~15,702 cases documented), as recorded by the spontaneous reporting systems in the U.S. and Europe. Five of these cases occurred in persons under 18 years old. Moreover, a systematic published review of the international literature found 0.22% (n=30) of 13, 571 covid vaccine-associated myocarditis or pericarditis events were fatal

Fatalities following myocarditis and pericarditis after COVID-19 mRNA vaccines
“There have been cases of myocarditis and pericarditis with a fatal outcome reported to spontaneous reporting systems and in the literature. There were four fatalities in the UK (0.25% of all spontaneous reports; [so n~1600 total reports]), 62 in the USA (1.3% of all reports; [so ~4769 total reports]) and 56 in the EU/EEA (0.6% of all reports; [so 9333 total reports]). Where age of fatal cases was reported (EudraVigilance and VAERS databases only), 85.83% (n=103) of fatal cases overall were aged 18 years or older. Five cases (4.17%) were aged under 18 years; all were myocarditis events (6.41% of all fatal myocarditis events reported). Ten per cent of fatal cases had age unspecified. All fatal cases of pericarditis reported to EudraVigilance and VAERS were aged 18 years or older.
Fatal cases were reported in five of the 32 included studies identified by systematic literature review. Overall, 0.22% (n=30) of 13 571 myocarditis or pericarditis events reported in the literature had a fatal outcome. Characteristics of fatal cases were specified in one study. In this study, results indicated that fatal cases of myocarditis and pericarditis occurred in the adult population. There were 15 fatal myocarditis events (median age 60 (IQR 56–78) years), 5 fatal pericarditis events (median age 71 (IQR 67–77) years) and 2 fatal myopericarditis events (aged 55 and 83 years)”
