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. Of the 323 persons meeting CDCs case definitions, 309 (96%) were hospitalized. Myocarditis Following Immunization With mRNA COVID-19 Vaccines in Members of the US Military. government site.

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. 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). FLEG: The NHLBI has a strong history of conducting and funding research on myocarditis. The risk of myocarditis linked with COVID-19 illness is several times greater than the risk from vaccination, and it is often more serious.3,5,8 This is because the SARS-CoV-2 virus invades cells of the heart, plus the body generates an overactive immune response to the infection.

Myocarditis is very uncommon, but it has been on the rise since the pandemic began. endorsement of these organizations or their programs by CDC or the U.S. When reported, the cases have especially been in adolescents and young adult males within several days after mRNA COVID-19 vaccination (Pfizer-BioNTech or Moderna). Diagnostic evaluation might reveal an elevated troponin level or abnormal findings on electrocardiogram, echocardiogram, or cardiac magnetic resonance imaging (Table 1). 2 0 obj 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. Among men ages 18 to 29 who received the Moderna vaccine, the rate was 22.9 per 100,000 doses. 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. FLEG: The bottom line is this: The benefits of getting vaccinated markedly outweigh the very small risk of vaccine-related myocarditis. Risks of myocarditis, pericarditis, and cardiac arrhythmias associated with COVID-19 vaccination or SARS-CoV-2 infection. 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. %PDF-1.7 The review said they were all either elderly or had other health conditions.

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. 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. The 120-day period was selected because 1) no alternative vaccine options currently exist for persons aged <18 years or are expected to be available during this period, and 2) inputs regarding community transmission have high uncertainty beyond this period, particularly in the context of circulating variants.. For more severe cases of myocarditis caused by a virus, such as SARS-CoV-2, people may need to stay in the hospital for a week or two often in the ICU. 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).

Higher levels of vaccination coverage can reduce community transmission, which can protect against development and circulation of emerging variants. Though both complications were rare, data from Ontario show higher rates of myocarditis and pericarditis with the Moderna COVID-19 vaccine than with the Pfizer-BioNTech vaccine, but the rates were lower for both vaccines if the spacing between receiving two doses was extended, according to a study late last week in JAMA Network Open..
