Myocarditis and pericarditis only appear in children and adolescents after COVID vaccination and not after infection, according to a new large-scale study from scientists at the University of Oxford.
The two conditions are inflammatory conditions of the heart and are generally considered to be rare. Severe cases can lead to serious complications and even death.
The new study looked at more than 1 million English children and adolescents aged between five and 11 and 12 and 15. The study compared vaccinated and unvaccinated subjects, and also took into account the number of doses of vaccine received.
“Whilst rare, all myocarditis and pericarditis events during the study period occurred in vaccinated individuals,” the researchers wrote.
The study noted that hospitalization related to COVID-19 was extremely rare among children and adolescents, and there were no deaths recorded among the entire subject population.
