Background: The COVID-19 pandemic adversely affected the severity and prognosis of patients with acute myocardial infarction (MI) caused by atherothrombosis (type 1 MI). The effect, if any, of COVID-19 vaccination and natural SARS-CoV2 serologic immunity in these patients is unclear. Our aim was to analyze the association between the severity and outcome of patients with type… Continue reading Association of #SARS-CoV-2 immunoserology and #vaccination status with #myocardial infarction severity and outcome

A case of biopsy-proven inflammatory dilated #cardiomyopathy following heterologous #mRNA -1273 third-dose immunization
Advances in mRNA vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have helped curb the coronavirus disease 2019 (COVID-19) pandemic and prevent disease onset and severity. Growing cases of vaccine-associated myocarditis (VAM) following SARS-CoV-2 immunization have been reported. Although COVID-19 VAM commonly occurs in young males after the second dose of vaccination, most cases are… Continue reading A case of biopsy-proven inflammatory dilated #cardiomyopathy following heterologous #mRNA -1273 third-dose immunization
A Systematic REVIEW of #Autopsy findings in deaths after #covid-19 vaccination
Highlights•We found that 73.9% of deaths were directly due to or significantly contributed to by COVID-19 vaccination.•Our data suggest a high likelihood of a causal link between COVID-19 vaccination and death.•These findings indicate the urgent need to elucidate the pathophysiologic mechanisms of death with the goal of risk stratification and avoidance of death for the… Continue reading A Systematic REVIEW of #Autopsy findings in deaths after #covid-19 vaccination
#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
Inability to work following #COVID-19 vaccination-a relevant aspect for future booster vaccinations
Objectives: COVID-19 vaccination is a key prevention strategy to reduce the spread and severity of SARS-CoV-2 infections. However, vaccine-related inability to work among healthcare workers (HCWs) could overstrain healthcare systems.Study design: The study presented was conducted as part of the prospective CoVacSer cohort study.Methods: This study examined sick leave and intake of pro re nata medication after the… Continue reading Inability to work following #COVID-19 vaccination-a relevant aspect for future booster vaccinations
Increased emergency cardiovascular events among under-40 population in Israel during vaccine rollout and third COVID-19 wave
Cardiovascular adverse conditions are caused by coronavirus disease 2019 (COVID-19) infections and reported as side-effects of the COVID-19 vaccines. Enriching current vaccine safety surveillance systems with additional data sources may improve the understanding of COVID-19 vaccine safety. Using a unique dataset from Israel National Emergency Medical Services (EMS) from 2019 to 2021, the study aims… Continue reading Increased emergency cardiovascular events among under-40 population in Israel during vaccine rollout and third COVID-19 wave
IgG4 Antibodies Induced by Repeated Vaccination May Generate Immune Tolerance to the SARS-CoV-2 Spike Protein
Less than a year after the global emergence of the coronavirus SARS-CoV-2, a novel vaccine platform based on mRNA technology was introduced to the market. Globally, around 13.38 billion COVID-19 vaccine doses of diverse platforms have been administered. To date, 72.3% of the total population has been injected at least once with a COVID-19 vaccine.… Continue reading IgG4 Antibodies Induced by Repeated Vaccination May Generate Immune Tolerance to the SARS-CoV-2 Spike Protein
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
