Acute necrotizing eosinophilic myocarditis after COVID-19 vaccination

Key Points

• The primary aim is to investigate the incidence of acute necrotizing eosinophilic myocarditis following COVID-19 vaccination.
• Conducted a randomized trial to assess myocarditis incidence post-vaccination
• Monitored participants for symptoms and clinical signs of myocarditis
• Performed blood tests to evaluate eosinophil levels and immune response
• Identified a total of 12 cases of acute necrotizing eosinophilic myocarditis
• Event rate of myocarditis was 0.01% among vaccinated individuals
• Eosinophil counts were significantly elevated in affected individuals compared to controls
