G., Draper, C., Ghildayal, N., Harris, A. M., Kappelman, M. D., Ko, J. Y., Mayer, K. H., Nagavedu, K., Oster, M. E., Paranjape, A., Puro, J., Ritchey, M. D., Gundlapalli, A. V. (2022). mRNA Vaccine Technology: A Promising Idea for Fighting HIV, Testing of mRNA HIV vaccines in humans is underway. Yes. The cases have been most common in male adolescents and young adults, occurring most often after the second dose, and usually within several days of receiving the vaccine. 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. Baseline incidence rates (IRs), and vaccine- and dose-specific IRs and rate differences were calculated from the cohort The SCRI calculated calendar time-adjusted IR ratios (IRR), using a 60-day pre-vaccination control period and dose-specific . To describe reports of myocarditis and the reporting rates after mRNA-based COVID-19 vaccination in the US. Chavda VP, Bezbaruah R, Valu D, Patel B, Kumar A, Prasad S, Kakoti BB, Kaushik A, Jesawadawala M. Vaccines (Basel). 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. ** 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. Researchers also looked at rates per million doses and the rate was 35.6 cases per million for Moderna and 12.6 per million for Pfizer-;an almost threefold increase after Moderna shots vs..

Researchers added together cases after first and second doses to reach a total rate of 77 cases per million in this male age group triggered by vaccination, a sixth that seen after infection. Myocarditisisinflammation of the heart muscle. In a comprehensive analysis of 1,626 myocarditis cases in the U.S. VAERS, Oster, et al., concluded the highest rates of VAM are concentrated in young males, as follows: 6 70.6 per million in males 12-15 years 105.9 per million in males 16-17 years 52.4 per million for Pfizer-BioNTech and 56.3 million for Moderna per million in males 18-24 years. Vaccination with mRNA-1273 (Moderna) was associated with a significantly increased rate of myocarditis or myopericarditis, especially among individuals aged 12-39 years (adjusted hazard ratio 5.24 (95% confidence interval 2.47 to 11.12); absolute rate 5.7 (3.3 to 9.3) per 100 000 individuals aged 12-39 years within 28 days of vaccination) Since June 2020, ACIP has convened 15 public meetings to review data on COVID-19 epidemiology and use of COVID-19 vaccines.

The rate is significantly higher - 450 cases per million infections. (2022). 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 . 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. It is estimated there are around 2 more cases per 100,000 second vaccine doses in people under 40 who received Moderna original formulation than Pfizer original formulation. Importance: In cases of v-safe reports that include possible medically attended health events, CDCs v-safe call center follows up with the vaccine recipient to collect additional information for completion of a VAERS report.

FDA requires that vaccine providers report to VAERS vaccination administration errors, serious adverse events, cases of multisystem inflammatory syndrome, and cases of COVID-19 that result in hospitalization or death after administration of a COVID-19 vaccine under an EUA.

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.. Reports of myocarditis to VAERS were adjudicated and summarized for all age groups. Of the 323 persons meeting CDCs case definitions, 309 (96%) were hospitalized. For persons younger than 30 years of age, medical record reviews and clinician interviews were conducted to describe clinical presentation, diagnostic test results, treatment, and early outcomes. Because these studies are in their early phases, the results are not ready yet. Expected rates of myocarditis by age and sex were calculated using 2017-2019 claims data. Some people may have minimal or no symptoms. Unfortunately, inflammation in the heart muscle can lead to serious complications, including heart failure, shock, or death.
