From the OP This report indicates that the vast majority of heart issues are mild. The report isn't avoiding the issue and is monitoring international reports regarding adverse reactions.
"TAGI notes that the TGA is investigating 1375 reports of suspected myocarditis and/or pericarditis following Pfizer and in particular 404 suspected myocarditis reports. Of these suspected cases, 235 cases of myocarditis or myopericarditis have been assessed as meeting the Brighton Collaboration case definition (level 1, 2, or 3), of which 140 cases occurred following the second dose.
ATAGI notes that the TGA report details the estimated rate of myocarditis following first and second doses by age and sex.
The observed rates are consistent with international data showing a higher rate in younger individuals (particularly younger males) and following second doses.
Most reported cases have been mild, self-limiting and have recovered quickly, although further follow-up of these cases is ongoing.
ATAGI noted that a small number of cases were more severe, requiring hospitalisation."
