FLEG: Vaccination helps protect people from getting sick or severely ill with COVID-19 and helps protect those around them. 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 .

Since April, more than 1,000 cases of inflammation of the . 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. However, COVID-19 illness is far more likely to cause myocarditis than are the vaccines. *** The highest reporting rates were among males aged 1217 years and those aged 1824 years (62.8 and 50.5 reported myocarditis cases per million second doses of mRNA COVID-19 vaccine administered, respectively).

**** The risks were assessed as the number of myocarditis patients reported to VAERS that occurred within 7 days of receipt of a second dose of an mRNA COVID-19 vaccine per million second doses administered through the week of June 11, 2021. The benefit-risk assessment was stratified by age group and sex. Within the Vaccine Adverse Event Reporting System (VAERS) (4), the national vaccine safety passive monitoring system, 1,226 reports of myocarditis after mRNA vaccination were received during December 29, 2020June 11, 2021. mmwrq@cdc.gov. FLEG: The bottom line is this: The benefits of getting vaccinated markedly outweigh the very small risk of vaccine-related myocarditis. It is unclear how many of these cases are a direct consequence of the vaccine versus coincidental. Epidemiology of Myocarditis and Pericarditis Following mRNA Vaccination by Vaccine Product, Schedule, and Interdose Interval Among Adolescents and Adults in Ontario, Canada. Among males aged 30 years, 15,300 COVID-19 cases, 4,598 hospitalizations, 1,242 ICU admissions, and 700 deaths could be prevented, compared with three to four expected myocarditis cases after COVID-19 vaccination. The clinical presentation and severity of myocarditis vary among patients. Figure 1.. Cases of Myocarditis After mRNA-Based, Figure 1.. Cases of Myocarditis After mRNA-Based COVID-19 Vaccination by Age at Onset of Myocarditis, Figure 2.. Cases of Myocarditis After mRNA-Based, Figure 2.. Cases of Myocarditis After mRNA-Based COVID-19 Vaccination by Time From Vaccination to Symptom, MeSH The rates of myocarditis 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 vaccine Cordero, A., Cazorla, D., Escribano, D., Quintanilla, M.

Treatment data in VAERS are preliminary and incomplete; however, many patients have experienced resolution of symptoms with conservative treatment, such as receipt of nonsteroidal antiinflammatory drugs. Myocarditis related to COVID-19 vaccines seems to be caused by the bodys immune response to vaccination. Overall, the investigators found 2.13 myocarditis cases per 100,000 peopleagain, about a 0.002% incidencewith the highest incidence in men 16 to 29 years old, where it was 10.69 cases per 100,000 people, or a 0.011% incidence (95% CIs, 1.56 to 2.70 and 6.93 to 14.46, respectively). There were 826 cases of myocarditis among those younger than 30 years of age who had detailed clinical information available; of these cases, 792 of 809 (98%) had elevated troponin levels, 569 of 794 (72%) had abnormal electrocardiogram results, and 223 of 312 (72%) had abnormal cardiac magnetic resonance imaging results. The median age of the 323 patients meeting CDCs case definitions was 19 years (range=1229 years); 291 were male, and 32 were female.

In a comprehensive analysis of 1,626 myocarditis cases in the U.S. VAERS, Oster, et al., concluded the highest rates of VAM are concentrated in young males, as follows: 6 70.6 per million in males 12-15 years 105.9 per million in males 16-17 years 52.4 per million for Pfizer-BioNTech and 56.3 million for Moderna per million in males 18-24 years. In those aged under 18 years, the reported rate for heart inflammation (myocarditis and pericarditis) was 13 per million first doses and 8 per million second doses of the monovalent.

FLEG: The NHLBI has a strong history of conducting and funding research on myocarditis. Among teenaged boys the group with the highest risk of myocarditis after COVID-19 vaccination the risk is between 2 and 5 times higher after SARS-CoV-2 infection than after vaccination.10, A study of children ages 12 to 17 in England estimated that COVID-19 vaccination prevented 4,500 hospitalizations, 300 ICU hospital stays, and 36 deaths during the summer of 2021 when infection rates were high.11, Children with myocarditis linked with vaccination are less likely to be hospitalized, admitted to the ICU, or need ventilator support, compared with children who had myocarditis after a COVID-19 diagnosis.

Side effects of COVID-19 vaccination are generally mild discomfort at the injection site, fatigue, and muscle aches and go away in a few days. In cases of v-safe reports that include possible medically attended health events, CDCs v-safe call center follows up with the vaccine recipient to collect additional information for completion of a VAERS report.
