The interesting table with absolute numbers is on page 18 of [0]. Expected and observed cases are cases of myocarditis / pericarditis here. Crude rate is the number of cases per 1 million administered doses. Use landscape mode if you are reading this from a mobile device, the table is narrow enough for that.

  Age group  Doses       Crude   Expected Observed 
              administ.   rate    cases    cases

  12–15 yrs    134,041    22.4     0–1        2
