The Hospital for Sick Children (SickKids) is reporting a handful of cases of myocarditis — inflammation of the heart — after patients received the mRNA-based COVID-19 vaccines Pfizer or Moderna. Benefit of vaccine 'far outweighs the risk'Ontario's incoming medical officer of health, Dr. Kieran Moore, urged parents not to worry at Thursday's COVID-19 briefing. "In our opinion ... the benefit of the vaccine far outweighs the risk of myocarditis or pericarditis at present," Moore said. PHAC: No clear association establishedThe Public Health Agency of Canada is also monitoring reports of heart inflammation following immunization. The agency's latest weekly report on reported side effects following vaccination says that based on reports received, "Health Canada and PHAC are not seeing higher rates than would normally be expected in the general population."
