[Correspondence] Vascular and inflammatory diseases after COVID-19 infection and vaccination in children

In this cohort study,1 based on the whole English population younger than 18 years, Alexia Sampri and colleagues addressed a topic of great interest. However, their interpretation that the “findings…support the public health strategy of COVID-19 vaccination in children and young people” is not transparent. Indeed, they state that “crude incidence rates for all outcomes, with the exception of myocarditis or pericarditis, were generally lower for those who were vaccinated than unvaccinated” (p 844).
