Does the COVID-19 vaccination period increase the incidence of myocarditis and pericarditis emergency department or inpatient hospital encounters compared to the pre-vaccination period?
Does the COVID-19 vaccination period increase the incidence of myocarditis and pericarditis emergency department or inpatient hospital encounters compared to the pre-vaccination period?
Higher myocarditis/pericarditis encounters during early rollout warrant continued surveillance; leaves open direct causality versus confounding.
This study investigates the incidence of myocarditis and pericarditis emergency department or inpatient hospital encounters before COVID-19 vaccine availability (January 2019–January 2021) and during a COVID-19 vaccination period (February-May 2021) in a large US health care system.
