COVID-19 vaccination is strongly associated with a serious adverse safety signal of myocarditis, particularly in children and young adults resulting in hospitalization and death. Further investigation into the underlying mechanisms of COVID-19 vaccine-induced myocarditis is imperative to create effective mitigation strategies and ensure the safety of COVID-19 vaccination programs across populations.
Determinants of COVID-19 vaccine-induced myocarditis
If myocarditis has developed after the first injection, then subsequent administrations should be avoided at all costs. Sustained elevations of cardiac troponin, reduction in left and right ventricular function, large areas of inflammation or scar on imaging, and cardiac arrhythmias all portend a poor prognosis for the development of heart failure and cardiac death.
Determinants of COVID-19 vaccine-induced myocarditis
We found the number of myocarditis reports in VAERS after COVID-19 vaccination in 2021 was 223 times higher than the average of all vaccines combined for the past 30 years. This represented a 2500% increase in the absolute number of reports in the first year of the campaign when comparing historical values prior to 2021.
