Abstract

ABSTRACT Objectives Establishing the rate of post-vaccination cardiac myocarditis in the 12-15 and 16-17-year-old population in the context of their COVID-19 hospitalization risk is critical for developing a vaccination recommendation framework that balances harms with benefits for this patient demographic. Design, Setting and Participants Using the Vaccine Adverse Event Reporting System (VAERS), this retrospective epidemiological assessment reviewed reports filed between January 1, 2021, and June 18, 2021, among adolescents ages 12-17 who received mRNA vaccination against COVID-19. Symptom search criteria included the words chest pain, myocarditis, pericarditis and myopericarditis to identify children with evidence of cardiac injury. The word troponin was a required element in the laboratory findings. Inclusion criteria were aligned with the CDC working case definition for probable myocarditis. Stratified cardiac adverse event (CAE) rates were reported for age, sex and vaccination dose number. A harm-benefit analysis was conducted using existing literature on COVID-19-related hospitalization risks in this demographic. Main outcome measures 1) Stratified rates of mRNA vaccine-related myocarditis in adolescents age 12-15 and 16-17; and 2) harm-benefit analysis of vaccine-related CAEs in relation to COVID-19 hospitalization risk. Results A total of 253 CAEs were identified. Rates per million following dose 2 among males were 162.2 (ages 12-15) and 93.0 (ages 16-17); among females, rates were 13.0 and 12.5 per million, respectively. For boys 12-15 without medical comorbidities receiving their second mRNA vaccination dose, the rate of CAE is 2.6 to 4.3 times higher than their 120-day COVID-19 hospitalization risk even at times of peak incidence such as during the delta wave (7-day hospitalizations 2.1/100k population). For boys 16-17 without medical comorbidities, the rate of CAE is 1.5 to 2.5 times higher at times of high weekly COVID-19 hospitalization. Conclusions Post-vaccination CAE rate was highest in young boys aged 12-15 following dose two. For boys 12-17 without medical comorbidities, the likelihood of post vaccination dose two CAE is 162.2 and 93.0/million respectively. This incidence exceeds their expected 120-day COVID-19 hospitalization rate at both moderate and high COVID-19 hospitalization incidence. Further research into the severity and long-term sequelae of post-vaccination CAE is warranted. Quantification of the benefits of the second vaccination dose and vaccination in addition to natural immunity in this demographic may be indicated to minimize harm.

    The Methods and Results (page not provided) describe VAERS reports of myocarditis and pericarditis in adolescents, predominantly males who received Pfizer-BioNTech vaccine. The Principal findings (page not provided) also discuss reported myocarditis rates after Moderna vaccination. The copy does not support the claims about anaphylaxis across all COVID-19 vaccines or thrombocytopenia syndrome among premenopausal Janssen recipients. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
