CDC has provided guidance regarding evaluation and management of myocarditis after mRNA COVID-19 vaccine (https://www.cdc.gov/vaccines/covid-19/clinical-considerations/myocarditis.html), as well as considerations for a second vaccine dose in persons who develop myocarditis after a first dose (https://www.cdc.gov/vaccines/covid-19/info-by-product/clinical-considerations.html). Users are referred to the electronic PDF version (https://www.cdc.gov/mmwr) Klamer, T. A., Linschoten, M., & Asselbergs, F. W. (2022). The NHLBI supports and conducts research aimed at understanding risk factors for COVID-19, developing prevention and treatment strategies, and finding ways to hasten and enhance recovery. If you have already gotten the first dose of Pfizer-BioNTech or Moderna vaccine, or if your child has already gotten the first dose of the Pfizer-BioNTech vaccine, its important to get the second dose unless a vaccination provider or your doctor tells you not to get it. For the BNT162b2 vaccine, there were 114246837 first vaccination doses and 95532396 second vaccination doses; and for the mRNA-1273 vaccine, there were 78158611 and 66163001, respectively. A., & American Heart Association Pediatric Heart Failure and Transplantation Committee of the Council on Lifelong Congenital Heart Disease and Heart Health in the Young and Stroke Council (2021). Pediatrics 2011;127(Suppl 1):S4553. Risks of myocarditis, pericarditis, and cardiac arrhythmias associated with COVID-19 vaccination or SARS-CoV-2 infection. More often after the second dose 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. Am J Cardiovasc Pathol 1987; 1:314). Myopericarditis after vaccination, Vaccine Adverse Event Reporting System (VAERS), 1990-2018. MMWR. official website and that any information you provide is encrypted Myocarditis was reported at a higher rate than expected among some people who received the Pfizer or Moderna vaccines, according to a July 2021 study. Last week, after reviewing data from a clinical . ". Vasudeva R, Bhatt P, Lilje C, et al. The .gov means its official. The y-axis range differs between panels A and B. *** 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). SARS-CoV-2 can cause serious heart problems by infecting heart cells and by causing inflammation that injures the heart muscle. Centers for Disease Control and Prevention. Follow-up is ongoing to identify and understand longer-term outcomes after myocarditis occurring after COVID-19 vaccination. The analysis assumed 95% vaccine effectiveness of 2 doses of a mRNA COVID-19 vaccine in preventing COVID-19 cases and hospitalization and assessed outcomes for a 120-day period. Viruses. 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. Data sources: Klamer et al., 2022; Cordero et al., 2022; National Weather Service. 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 and the mRNA-1273 vaccine, respectively). The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. . Overall myocarditis rates among males in this age group were 2.97 per 100,000, which rose to 2.27 per 100,000 after the second dose. Myocarditis Cases After mRNA-Based COVID-19 Vaccination in the US. Evidence suggests that AstraZeneca and Novavax are probably associated with a small increased risk of myocarditis and pericarditis. The risks and outcomes of myocarditis after COVID-19 vaccination are unclear. https://gis.cdc.gov/grasp/COVIDNet/COVID19_3.html. That means the vaccines protect heart health. Reporting rates of adverse events following COVID-19 vaccination, including those from booster doses, are very stable. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Presence of 2 new or worsening of the following clinical features: new ST-elevation or PR-depression on EKG, new or worsening pericardial effusion on echocardiogram or MRI. After reports of myocarditis and pericarditis in mRNA vaccine recipients, which predominantly occurred in young males after the second dose, an ACIP meeting was rapidly convened to review reported cases of myocarditis and pericarditis and discuss the benefits and risks of mRNA COVID-19 vaccination in the United States. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. FLEG: Vaccination helps protect people from getting sick or severely ill with COVID-19 and helps protect those around them. The work group also reviewed a benefit-risk assessment of myocarditis events after receipt of mRNA COVID-19 vaccines, considering recent epidemiology of COVID-19 and sequelae of COVID-19, including myocarditis and multisystem inflammatory syndrome in children (MIS-C). Using myocarditis cases reported to VAERS with onset within 7 days after dose 2 of an mRNA vaccine, crude reporting rates (i.e., using confirmed and unconfirmed cases) per million second dose recipients were calculated using national COVID-19 vaccine administration data as of June 11, 2021. sharing sensitive information, make sure youre on a federal The risk after both doses of the Moderna vaccine in people age 18 to 39 was as much as 37 times as high as in the general population, and the rate after two doses of the Pfizer-BioNTech vaccine.

Snchez, The Research Institute at Nationwide Childrens Hospital. Drs Barnett, Ruberg, and Smith reported receiving grants from Pfizer. We dont know exactly how often this happens, but one study estimated that myocarditis affects about 40 people out of every 1,000,000 people who test positive for COVID-19.3 However, myocarditis is much more common in patients hospitalized for COVID-19 (226 per 100,000). Among men ages 18 to 29 who received the Moderna vaccine, the rate was 22.9 per 100,000 doses. Clipboard, Search History, and several other advanced features are temporarily unavailable. Vaccine 2015;33:4398405. 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. You can review and change the way we collect information below. The Vaccine Safety Datalink: a model for monitoring immunization safety. Severe myocarditis can cause long-lasting heart damage or even death. The rate is significantly higher - 450 cases per million infections. Recent research about myocarditis, . Thank you for taking the time to confirm your preferences. 2022 May 24;327(20):2019-2020. doi: 10.1001/jama.2022.5131. Continued use of mRNA COVID-19 vaccines in all recommended age groups will prevent morbidity and mortality from COVID-19 that far exceed the number of cases of myocarditis expected. 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. 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. Lancet. An analysis of almost 400 patients with myocarditis linked with COVID-19 illness found that about 15% died within 6 months.9. Buonsenso D, Munblit D, De Rose C, et al. Ho, J. S., Sia, C.-H., Chan, M. Y., Lin, W., & Wong, R. C. (2020). In December 2020, the Food and Drug Administration (FDA) issued Emergency Use Authorizations (EUAs) for the Pfizer-BioNTech COVID-19 (BNT162b2) vaccine and the Moderna COVID-19 (mRNA-1273) vaccine, and the Advisory Committee on Immunization Practices (ACIP) issued interim recommendations for their use in persons aged 16 years and 18 years, respectively. In May 2021, FDA expanded the EUA for the Pfizer-BioNTech COVID-19 vaccine to include adolescents aged 1215 years; ACIP recommends that all persons aged 12 years receive a COVID-19 vaccine. Some people may have minimal or no symptoms. URL addresses listed in MMWR were current as of Patients can usually return to their normal daily activities after their symptoms improve. The known risks of COVID-19 illness and its related, possibly severe complications, such as long-term health problems, hospitalization, and even death, far outweigh the potential risks of having a rare adverse reaction to vaccination, including the possible risk of myocarditis or pericarditis. Kyt V, Sipil J, Rautava P. The effects of gender and age on occurrence of clinically suspected myocarditis in adulthood. Table 2. Federal government websites often end in .gov or .mil. Chavda VP, Bezbaruah R, Valu D, Patel B, Kumar A, Prasad S, Kakoti BB, Kaushik A, Jesawadawala M. Vaccines (Basel). J Med Toxicol. The ACIP recommendation for use of mRNA COVID-19 vaccines under an EUA is interim and will be updated as additional information becomes available. 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. MMWR Morb Mortal Wkly Rep 2021;70:977982. In addition, CDC has developed a voluntary smartphone-based online tool (v-safe) that uses text messaging and online surveys to provide near real-time health check-ins after receipt of a COVID-19 vaccine. DOI: http://dx.doi.org/10.15585/mmwr.mm7027e2external icon. The reports to the Vaccine Adverse Event Reporting System met the case definition of myocarditis (reported cases). To assess the benefit-risk balance of mRNA vaccines in adolescents and young adults, ACIP reviewed an individual-level assessment that compared the benefits (i.e., COVID-19 infections and severe disease prevented) to the risks (number of cases of myocarditis) of vaccination, using methods similar to those described previously. Specifically, the benefits per million second doses administered (i.e., the benefits of being fully vaccinated in accordance with the FDA EUA) were assessed, including 1) COVID-19 cases prevented based on rates the week of May 29, 2021; 2) COVID-19 hospitalizations prevented based on rates the week of May 22, 2021; and 3) COVID-19 intensive care unit (ICU) admissions and deaths prevented based on the proportion of hospitalized patients who were admitted to the ICU or died. A histopathologic definition and classification. Myocarditis is an inflammation of the heart muscle; if it is accompanied by pericarditis, an inflammation of the thin tissue surrounding the heart (the pericardium), it is referred to as myopericarditis. ** The ACIP COVID-19 Vaccines Safety Technical (VaST) Work Group, comprising independent vaccine safety expert consultants, had also reviewed safety data on myocarditis after receipt of mRNA COVID-19 vaccines at its weekly meetings.
