The purpose of this study is to learn about the safety and effects of the vaccine (called COMIRNATY) for the potential prevention of COVID-19. This study is seeking participants who:
This study will examine the potential long-term effects associated with myocarditis/pericarditis following vaccination with COMIRNATY. The association of myocarditis/pericarditis in participants who received the study vaccine (COMIRNATY) compared with those associated with COVID-19 will also be examined. This will help us determine if COMIRNATY is safe and effective, and if there is a myocarditis/pericarditis association that should be noted. Participants will take part in this study for up to 5 years. During this time, they will receive complete cardiac imaging tests, and have follow up visits per guidance stated in the study protocol.
This is a low-interventional cohort study to determine cardiac and non-cardiac long-term outcomes of persons <21 years of age with myocarditis/pericarditis after the administration of COMIRNATY, compared with similarly aged persons with myocarditis/pericarditis associated with COVID-19, including MIS-C.
To be classified as having COMIRNATY-associated myocarditis/pericarditis, a person must 1) meet the CDC case definition for probable or confirmed myocarditis/pericarditis, 2) have received any dose of COMIRNATY ≤ 21 days of symptom onset, and 3) have no other plausible alternative etiology at the time of enrollment.
To be classified as having myocarditis/pericarditis associated with COVID-19, a person must have 1) either acute severe COVID-19 infection or MIS-C, as defined by the CDC, 2) findings of probable or confirmed myocarditis in the CDC definition, 3) no other plausible alternative etiology. A description of the three cohorts is as follows:
Cohort 1: Prospectively ascertained cases of probable or confirmed myocarditis/pericarditis associated with COMIRNATY , i.e., participants enrolled under protocol during hospitalization or </= 2 weeks of hospital discharge.
Cohort 2: Retrospectively ascertained cases of probable or confirmed myocarditis/pericarditis associated with COMIRNATY , i.e., participants enrolled > 2 weeks after hospital discharge. Participants can be retrospectively ascertained and enrolled at any time from their COMIRNATY-associated myocarditis/pericarditis.
Cohort 3: Comparator cohort of COVID-19- related myocarditis/pericarditis , including MIS-C, both retrospectively and prospectively ascertained, and enrolled at any time from their COVID-19 or MIS-C associated myocarditis/pericarditis diagnosis. Cohort 3 participants will not be stratified by MIS-C diagnosis because of the rarity of myocardial involvement in children with acute severe COVID-19
Participants in all cohorts will be those who present to participating medical centers for care. This study is a collaboration between the National Heart, Lung, and Blood Institute (NHLBI)'s Pediatric Heart Network (PHN) and Pfizer.
Enrollment will include approximately 200 prospectively and retrospectively ascertained cases of children, adolescents, and young adults <21 years of age who receive care for myocarditis/pericarditis associated with COMIRNATY (Cohort 1 and 2); and approximately 100 persons <21 years of age with COVID -19-associated myocarditis/pericarditis, including MIS-C (Cohort 3).

| Composite findings of myocarditis | This is a single composite primary outcome measure. This primary composite study endpoint is defined as the presence of 1 or more of the following 6 months after illness onset: left ventricular dysfunction (LVEF < 55% by echocardiogram), findings of myocarditis by original or revised Lake Louise criteria on cardiac MRI, or the presence of high-grade arrhythmia or conduction system disturbance on ECG or ambulatory monitoring. | 6 months after illness onset |
| Left ventricular ejection fraction (LVEF) < 55% by echocardiography | Up to 5 years following illness onset. | |
| Myocarditis by original or revised Lake Louise criteria on cMRI | Up to 5 years following illness onset. | |
| Arrhythmias on cardiac recording (ECG, ambulatory monitoring) | Up to 5 years following illness onset. | |
| Complications, including non-cardiac morbidities by medical history | Up to 5 years following illness onset. | |
| Functional Status by Behavior Assessment System for Children, Third Edition BASC-3 or PROMIS Short Forms | Behavior Assessment System for Children, Third Edition (BASC-3), <8 yr (T score <30->70 with higher number meaning lower functioning) or PROMIS Short Forms ≥8 yr (scores from 3-15 with higher number meaning better functioning) | Up to 5 years following illness onset. |
| The Pediatric Quality of Life Inventory (PEDS QL) | The 27 question, age-appropriate and parent-proxy questionnaires, will be used in 2 to <18-year-old participants to assess quality of life. Scores span 0-108 with higher number being better functioning. |
| Measure | Description | Time Frame |
|---|---|---|
| Left ventricular ejection fraction (LVEF) by echocardiogram as a measure of myocardial performance. | During the hospitalization or within 2 weeks of hospital discharge, generally obtained less than 3 weeks from presentation. | |
| Time to recovery of myocardial inflammation and injury by Lake Louise (the original or revised) criteria |
