CDC and FDA will continue to closely monitor reports of myocarditis after receipt of the mRNA COVID-19 vaccines and will bring any additional data to ACIP for consideration. * These authors contributed equally to this work. This analysis did not include the potential benefit of preventing post-COVID-19 conditions, such as prolonged symptoms and MIS-C (6,7). The most common treatment was nonsteroidal anti-inflammatory drugs (589/676; 87%). The most common symptoms are chest pain, fever, fatigue, shortness of breath, and a rapid or irregular pulse. Reporting rates of adverse events following COVID-19 vaccination, including those from booster doses, are very stable. **** 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. That means the vaccines protect heart health. To describe reports of myocarditis and the reporting rates after mRNA-based COVID-19 vaccination in the US. Moderna defended the use of its Covid vaccine, saying the protection it offers against severe disease, hospitalization and death outweighs the risk of myocarditis. Risks of myocarditis, pericarditis, and cardiac arrhythmias associated with COVID-19 vaccination or SARS-CoV-2 infection. Were currently supporting two large studies looking at long-term effects of COVID-19, including myocarditis and other heart conditions.

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. The ACIP COVID-19 Vaccines Work Group, comprising experts in infectious diseases, vaccinology, vaccine safety, public health, and ethics, has held weekly meetings since April 2020 to review COVID-19 surveillance data, evidence for vaccine efficacy and safety, and implementation considerations for COVID-19 vaccination programs. The reports to the Vaccine Adverse Event Reporting System met the case definition of myocarditis (reported cases). CDC and its partners are actively monitoring reports of myocarditis and pericarditis after COVID-19 vaccination. This term may be used for patients who meet criteria for both myocarditis and pericarditis. Seek medical care if you or your child have any of the specific or general symptoms of myocarditis or pericarditis especially if its within a week after COVID-19 vaccination. The y-axis range differs between panels A and B. The estimated incidence of myocarditis was 2 per 100,000 individuals, with the highest reported rate in males aged 16 to 29. During the COVID-19 pandemic, Fleg turned his attention to the effects of SARS-CoV-2 infection on the heart, including myocarditis. In a Danish study preceding Covid-19 of 753 autopsied sudden death cases, the cause of death was myocarditis in 42 (6%) cases corresponding to an SCD-myocarditis incidence of 0.16 (95%CI: 0.11-0.21) per 100 000 person-years, but males had significantly higher incidence rates of SCD-myocarditis compared to females with an incidence rate ratio of . JAMA Netw Open 2021;4:e2116420. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. According to the TGA, the current overall estimated rates for the entire population of myocarditis for Pfizer and Moderna are similar - 1.4 cases per 100,000 Pfizer doses versus 1.8 cases per 100,000 Moderna doses. Shimabukuro TT, Nguyen M, Martin D, DeStefano F. Safety monitoring in the Vaccine Adverse Event Reporting System (VAERS). Chou, O., Zhou, J., Lee, T., Kot, T., Lee, S., Wai, A., Wong, W.

Comparison of COVID-19 Vaccine-Associated Myocarditis and Viral Myocarditis Pathology. in July asked Pfizer-BioNTech and Moderna to enroll more children in their clinical trials in order to detect less common side effects. Crude reporting rates were calculated across age and sex strata. Many people have no side effects at all. Based on passive surveillance reporting in the US, the risk of myocarditis after receiving mRNA-based COVID-19 vaccines was increased across multiple age and sex strata and was highest after the second vaccination dose in adolescent males and young men. Myocarditis linked with COVID-19 illness may also be more severe because these patients are usually older and have other health conditions that increase their risk of complications. Chavda VP, Bezbaruah R, Valu D, Patel B, Kumar A, Prasad S, Kakoti BB, Kaushik A, Jesawadawala M. Vaccines (Basel). Its also possible that myocarditis linked with vaccination is less serious because of the younger average age and healthier status of people getting vaccinated. There were no cases. The site is secure. The risks and outcomes of myocarditis after COVID-19 vaccination are unclear. The U.S. Food and Drug Administration on Friday added a warning to patient and provider fact sheets for the Pfizer and Moderna Covid-19 vaccines to indicate a rare risk of heart inflammation. Myocarditis. Am J Cardiol 2021;149:95102. Paul Burton, M.D., Ph.D., shared that data has found that there have been 13.3 cases of myocarditis per 100,000 people who received the Moderna vaccine compared to 2.7 cases per 100,000 people. Reporting rates (per 1 million doses administered) of myocarditis among females after Moderna COVID-19 vaccination, days 0-7 after vaccination (through Jan 13, 2022 6 Moderna (Females) Ages (years) Dose 1 Dose 2 18-24 0.5 5.5 25-29 0.3 5.8 30-39 0.6 0.6 40-49 0.8 1.6 50-64 0.8 0.4 65+ 0.1 0.5 85,729,766 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. official website and that any information you provide is encrypted Federal government websites often end in .gov or .mil.

Incidence, risk factors, natural history, and hypothesised mechanisms of myocarditis and pericarditis following covid-19 vaccination: living evidence syntheses and review. In a population-based cohort study of adolescents and adults in Denmark who received two doses of the same mRNA vaccine against COVID, the risk of myocarditis or myopericarditis within 28 days. The ACIP recommendation for use of mRNA COVID-19 vaccines under an EUA is interim and will be updated as additional information becomes available. scientist on Monday, every million doses of the Pfizer vaccine administered to 16- and 17-year-old boys would be expected to cause 73 cases of the . The numbers of events per million persons aged 1229 years are the averages of numbers per million persons aged 1217 years, 1824 years, and 2529 years. Receipt of 2 doses of mRNA COVID-19 vaccine, compared with no vaccination. Case numbers have been rounded to the nearest hundred. Ranges calculated as 10% of crude VAERS reporting rates. Myocarditis is very uncommon, but it has been on the rise since the pandemic began. 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 . Myocarditis reporting rates were 40.6 cases per million second doses of mRNA COVID-19 vaccines administered to males aged 1229 years and 2.4 per million second doses administered to males aged 30 years; reporting rates among females in these age groups were 4.2 and 1.0 per million second doses, respectively. However, COVID-19 illness is far more likely to cause myocarditis than are the vaccines. Corresponding author: Sara E. Oliver, yxo4@cdc.gov. Recent research about myocarditis, . Active monitoring includes reviewing data and medical records and evaluating the relationship toCOVID-19vaccination. Potential cases of postvaccine myocarditis were identified based on reports . Feelings of having a fast-beating, fluttering, or pounding heart Myocarditis and pericarditis have rarely been reported. The median interval from vaccination to symptom onset was 2 days (range=040 days); 92% of patients experienced onset of symptoms within 7 days of vaccination. JAMA Netw Open.

H., Alkhaimy, H., Nanjundappa, A., & Elashery, A. Department of Health and Human Services. But the risk of myocarditis associated with the vaccine was lower than the risk associated with COVID-19 infection before or after vaccination - with one exception. In addition, CDC has updated patient education and communication materials reflecting this information for the Pfizer-BioNTech and Moderna****** COVID-19 vaccines; these are important to ensure that vaccine recipients, especially males aged 1229 years, are aware of increased risk for myocarditis and to seek care if they develop symptoms of myocarditis. Myocarditis typically causes shortness of breath and chest pain. They suggest the rates of myocarditis after the Moderna-NIAID vaccine may be two-and-a-half times higher. Diagnostic evaluation might reveal an elevated troponin level or abnormal findings on electrocardiogram, echocardiogram, or cardiac magnetic resonance imaging (Table 1). Most people (95%) who develop myocarditis after receiving a COVID-19 mRNA vaccine have only mild symptoms that go away within a few days. As of June 11, 2021, approximately 296 million doses of mRNA COVID-19 vaccines had been administered in the United States, with 52 million administered to persons aged 1229 years; of these, 30 million were first and 22 million were second doses. Descriptive study of reports of myocarditis to the Vaccine Adverse Event Reporting System (VAERS) that occurred after mRNA-based COVID-19 vaccine administration between December 2020 and August 2021 in 192 405 448 individuals older than 12 years of age in the US; data were processed by VAERS as of September 30, 2021. FLEG: Yes, but this is rare, and the symptoms are usually mild. One thing we don't know is the real rate of myocarditis with the original two-dose primary series of Pfizer and Moderna. July 5, 2022, U.S. Department of Health and Human Services, Benefits of COVID-19 vaccines outweigh a very small risk of heart complications, You can learn more about myocarditis symptoms, diagnosis, and treatment from the NHLBI, Countermeasures Injury Compensation Program, Researching COVID to Enhance Recovery (RECOVER), CONNECTS-Collaborative Cohort of Cohorts for COVID-19 Research (CONNECTS-C4R), https://covid.cdc.gov/covid-data-tracker/#vaccinations_vacc-total-admin-rate-total, https://doi.org/10.1161/CIR.0000000000001001, https://doi.org/10.1038/s41591-021-01630-0, https://doi.org/10.1016/j.hrtlng.2020.08.013, https://doi.org/10.1007/s12471-022-01677-9, https://doi.org/10.1016/j.vaccine.2020.12.046, https://doi.org/10.1016/j.ijcard.2022.01.037, https://doi.org/10.1007/s00392-022-02007-0, https://doi.org/10.1016/j.mayocpiqo.2021.12.006, https://doi.org/10.1177/01410768211052589, https://doi.org/10.1101/2021.10.05.21264581. COVID-19 is more likely than vaccines to cause myocarditis, and symptoms and outcomes are often worse. Rates of myocarditis and pericarditis were higher with the Moderna vaccine in both males and . It is unclear how many of these cases are a direct consequence of the vaccine versus coincidental. While the researchers did observe a higher risk among people that got the Moderna shot, it was still a relatively small risk. The CDC also needs to recommend . Patone, M., Mei, X.
