Adenoviral Vector-Based Vaccine Platform for COVID-19: Current Status. The y-axis range differs between panels A and B. Diagnosis and Management of Myocarditis in Children: A Scientific Statement from the American Heart Association. Of those with myocarditis, the median age was 21 years (IQR, 16-31 years) and the median time to symptom onset was 2 days (IQR, 1-3 days). Regarding health equity considerations, racial and ethnic minority groups have higher rates of COVID-19 and severe disease*****; potential changes in vaccine policy, or anything that would affect vaccination coverage for adolescents or young adults, might disproportionately affect those groups with the highest rates of poor COVID-19 outcomes. To describe reports of myocarditis and the reporting rates after mRNA-based COVID-19 vaccination in the US. Unauthorized use of these marks is strictly prohibited. Key Points There have been more than 1,200 reported cases of a myocarditis or pericarditis mostly in people 30 and under who received Pfizer's or Moderna's Covid-19 vaccine, according to CDC. *** Data collection for race/ethnicity of myocarditis cases is ongoing.

Myocarditis is a rare complication of COVID-19 vaccination. Am J Cardiol 2021;149:95102. It affects fewer than 20 people per 1,000,000 COVID-19 vaccinations.3,5,7 Only the mRNA vaccines (Pfizer-BioNTech and Moderna) have been linked with myocarditis. Expected rates of myocarditis by age and sex were calculated using 2017-2019 claims data. In young people aged 12-17 years (boys and girls combined), the rate of myocarditis or myopericarditis in Denmark was 1 per 100 000 with BNT162b2 compared with 18.5 per 100 000 in Hong Kong,3 and roughly 7 per 100 000 in Israel (ages 16-19 years).2 In 12-39 year old males after the second dose of BNT162b2, the incidence of myocarditis or . More often after the second dose The rates of myocarditis cases were highest after the second vaccination dose in adolescent males aged 12 to 15 years (70.7 per million doses of the BNT162b2 vaccine), in adolescent males aged 16 to 17 years (105.9 per million doses of the BNT162b2 vaccine), and in young men aged 18 to 24 years (52.4 and 56.3 per million doses of the BNT162b2 . "In general, the rate of myocarditis or myopericarditis was about threefold to fourfold higher for mRNA-1273 (Moderna) vaccination than that for BNT162b2 (Pfizer-BioNTech) vaccination," the study said. The study shows a low but significant rate of myocarditis among vaccine recipients, at less than 1 per 100,000 recipients.

CDC also encourages reporting of any additional clinically significant adverse event, even if it is not clear whether a vaccination caused the event. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. At the time of this report, 323 of these 484 cases were determined to meet criteria in CDCs case definitions for myocarditis, pericarditis, or myopericarditis by provider interview or medical record review (Table 1). Baseline incidence rates (IRs), and vaccine- and dose-specific IRs and rate differences were calculated from the cohort The SCRI calculated calendar time-adjusted IR ratios (IRR), using a 60-day pre-vaccination control period and dose-specific . MMWR. Recent research about myocarditis, . Among persons with reported myocarditis after mRNA vaccination, the median age was 26 years (range=1294 years), with median symptom onset interval of 3 days after vaccination (range=0179). Only about 1 out of 100 cases of heart inflammation linked with COVID-19 vaccines is life-threatening.5 An analysis of 627 cases of vaccine-linked myocarditis worldwide showed that 626 fully recovered and one fatality.7. NHLBI-supported research aims to identify the causes of lasting heart and lung symptoms of COVID-19, find ways to prevent these problems, and improve treatment to promote rapid healing. COVID-19 vaccines lower the risk of life-threatening heart problems and other serious health issues. Myocarditis is very uncommon, but it has been on the rise since the pandemic began. Myocarditis and Pericarditis After mRNA COVID-19 Vaccination, Centers for Disease Control and Prevention.
