Centers for Disease Control and Prevention. Id really like everyone to understand that the benefits of the COVID-19 vaccines strongly outweigh the very small risk of serious side effects. 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. On 9 July 2021, the COVID-19 subcommittee of the WHO Global Advisory Committee on Vaccine Safety (GACVS) issued a statement regarding reports of myocarditis and pericarditis following COVID-19 mRNA vaccines (1). The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Thank you for taking the time to confirm your preferences. 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. Myocarditis usually goes away on its own with supportive care, including IV fluids, steroid therapy, and medicines to treat disorders of heart rhythm or pumping function. Last week, after reviewing data from a clinical . 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. 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. * These authors contributed equally to this work.

Cases of Myocarditis After mRNA-Based COVID-19 Vaccination by Time From Vaccination to Symptom, MeSH However, the balance of benefits and risks varied by age and sex because cases of myocarditis were primarily identified among males aged <30 years, and the risks of poor outcomes related to COVID-19 increase with age. COVID-19 is more likely than vaccines to cause myocarditis, and symptoms and outcomes are often worse. If you have any health problems after vaccination, report them to theVaccine Adverse Event Reporting System. From the 1.8 million Moderna doses administered in Australia to 2 January 2022, there have been 40 reports of likely myocarditis and 52 reports of likely pericarditis [3]. https://www.sciencedirect.com/science/article/pii/S0735109718388430?via%3Dihubexternal icon** https://academic.oup.com/eurheartj/article/36/42/2921/2293375external icon Typically described as pain made worse by lying down, deep inspiration, or cough, and relieved by sitting up or leaning forward, although other types of chest pain might occur.
