Messenger RNA (mRNA) vaccines against SARS-CoV-2 are highly effective and were instrumental in curbing the COVID-19 pandemic. However, rare cases of noninfective myocarditis, particularly in young males and typically after the second dose, have been observed. Here, we explore the mediators of this myocarditis to better understand and to enhance the safety of future mRNA… Continue reading Inhibition of CXCL10 and IFN-γ ameliorates #myocarditis in preclinical models of SARS-CoV-2 #mRNA vaccination

The protective role of vitamin #D in BNT162b2 vaccine-related acute #myocarditis
Introduction: Vaccine-related myocarditis is recognized as a rare but important complication, especially after mass-scale mRNA COVID-19 vaccination. Knowledge regarding how to minimize the risk is limited. As NK cells can mediate acute myocarditis after mRNA COVID-19 vaccination and vitamin D may inhibit NK cells via cytokine modulation, we hypothesize that the myocarditis side effect is… Continue reading The protective role of vitamin #D in BNT162b2 vaccine-related acute #myocarditis
OpenSAFELY: Effectiveness of #COVID-19 #vaccination in #children and sadolescents
Background Children and adolescents in England were offered BNT162b2 as part of the national COVID-19 vaccine roll out from September 2021. We assessed the safety and effectiveness of first and second dose BNT162b2 COVID-19 vaccination in children and adolescents in England.Methods With the approval of NHS England, we conducted an observational study in the OpenSAFELY-TPP… Continue reading OpenSAFELY: Effectiveness of #COVID-19 #vaccination in #children and sadolescents
#Autopsy findings in cases of fatal #COVID-19 #vaccine -induced #myocarditis
COVID-19 vaccines have been linked to myocarditis, which, in some circumstances, can be fatal. This systematic review aims to investigate potential causal links between COVID-19 vaccines and death from myocarditis using post-mortem analysis. We performed a systematic review of all published autopsy reports involving COVID-19 vaccination-induced myocarditis through 3 July 2023. All autopsy studies that… Continue reading #Autopsy findings in cases of fatal #COVID-19 #vaccine -induced #myocarditis
Myocarditis Cases Reported After mRNA-Based COVID-19 Vaccination in the US From December 2020 to August 2021
Vaccination against COVID-19 provides clear public health benefits, but vaccination also carries potential risks. The risks and outcomes of myocarditis after COVID-19 vaccination are unclear.Objective To describe reports of myocarditis and the reporting rates after mRNA-based COVID-19 vaccination in the US.Design, Setting, and Participants Descriptive study of reports of myocarditis to the Vaccine Adverse Event Reporting System… Continue reading Myocarditis Cases Reported After mRNA-Based COVID-19 Vaccination in the US From December 2020 to August 2021
Fulminant myocarditis with complete atrioventricular block after mRNA COVID-19 vaccination: A case report
A 71-year-old man was transferred urgently to our hospital after collapsing near his home post the first shot of the BNT162b2 coronavirus disease 2019 vaccine (Pfizer-BioNTech, Comirnaty®). Immediately after arrival at our hospital, cardiac arrest due to complete atrioventricular block with no ventricular escaped beats was observed on electrocardiogram. Echocardiography showed preserved left ventricular ejection… Continue reading Fulminant myocarditis with complete atrioventricular block after mRNA COVID-19 vaccination: A case report
Circulating Spike Protein Detected in Post–COVID-19 mRNA Vaccine Myocarditis
BACKGROUND:Cases of adolescents and young adults developing myocarditis after vaccination with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)–targeted mRNA vaccines have been reported globally, but the underlying immunoprofiles of these individuals have not been described in detail.METHODS:From January 2021 through February 2022, we prospectively collected blood from 16 patients who were hospitalized at Massachusetts General… Continue reading Circulating Spike Protein Detected in Post–COVID-19 mRNA Vaccine Myocarditis

Persistent Cardiac Magnetic Resonance Imaging Findings in a Cohort of Adolescents with Post-Coronavirus Disease 2019 mRNA Vaccine Myopericarditis
We describe the evolution of cardiac magnetic resonance imaging findings in 16 patients, aged 12-17 years, with myopericarditis after the second dose of the Pfizer mRNA coronavirus disease 2019 vaccine. Although all patients showed rapid clinical improvement, many had persistent cardiac magnetic resonance imaging findings at 3- to 8-month follow-up. https://www.jpeds.com/article/S0022-3476(22)00282-7/fulltext ArticleDownload
