Incidence, risk factors, natural history, and hypothesised mechanisms of myocarditis and pericarditis following covid-19 vaccination: living evidence syntheses and review. Drs Barnett, Ruberg, and Smith reported receiving grants from Pfizer. Supportive therapy is a mainstay of treatment, with targeted cardiac medications or interventions as needed. The study showed males younger than 40 years old who received the Moderna vaccine were shown to have the highest rates of myocarditis, which according to the authors, may have implications for choosing specific vaccines for certain populations. xVMo8#Yi~*vSh6vm";Bk+;#{7BWAl)q7MgGSs]Hg>^Dx+2 2Mz49K-+i2\?')I!crVZ Pv)(v0Rv0`U4')>og)o|VA( CpN4yLc7zL''E->3`Vlk2dmUH'IS[X,sKWsQh &5ER(BBze?>M>#)V.

Evidence suggests that AstraZeneca and Novavax are probably associated with a small increased risk of myocarditis and pericarditis. On June 23, 2021, the Advisory Committee on Immunization Practices concluded that the benefits of COVID-19 vaccination to individual persons and at the population level clearly outweighed the risks of myocarditis after vaccination.

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. That means the vaccines protect heart health. Most people (95%) who develop myocarditis after receiving a COVID-19 mRNA vaccine have only mild symptoms that go away within a few days.5 Vaccine-linked myocarditis is less likely to cause lingering heart problems than myocarditis due to COVID-19 illness.

While the researchers did observe a higher risk among people that got the Moderna shot, it was still a relatively small risk. Researchers retract preprint study that miscalculated higher heart Abbreviations: AV = atrioventricular; cMRI=cardiac magnetic resonance imaging; ECG or EKG=electrocardiogram. Pericarditisis inflammation of the outer lining of the heart. Myocarditis typically causes shortness of breath and chest pain. ACIP emphasized the importance of informing vaccination providers and the public about the benefits and the risks, including the risk for myocarditis after COVID-19 vaccination, particularly for males aged 1229 years. 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. Men and boys between the ages of 16 and 29 have been most often affected by COVID-19vaccine-related myocarditis, usually a few days after their second dose.5 Myocarditis may be due to their strong immune response to the vaccine.

The Vaccine Safety Datalink: a model for monitoring immunization safety. 8600 Rockville Pike 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.

"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. MMWR and Morbidity and Mortality Weekly Report are service marks of the U.S. Department of Health and Human Services. 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.

COVID-19 Therapeutics: Use, Mechanism of Action, and Toxicity (Vaccines, Monoclonal Antibodies, and Immunotherapeutics). 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. Currently, about 1,000 cases of myocarditis and pericarditis have been reported after vaccination against COVID-19 with one of the mRNA vaccines, Pfizer/BioNTech or Moderna. 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. 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. 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. Most patients with myocarditis or pericarditis who received care responded well to medicine and rest and felt better quickly. Among recipients of either vaccine, there were only 13 reports or less of myocarditis beyond 10 days for any individual time from vaccination to symptom onset. Although numbers were too small to show rates in all subgroups by age, VSD data indicated increased risk of myocarditis in the 7 days after receipt of dose 1 or dose 2 of an mRNA COVID-19 vaccine compared with the risk 2242 days after the second dose, particularly among younger males after dose 2 (5). Most people (95%) who develop myocarditis after receiving a COVID-19 mRNA vaccine have only mild symptoms that go away within a few days. 2023 Feb 13;11(2):432. doi: 10.3390/vaccines11020432.
