A number of vaccines have been developed and deployed globally to restrain the spreading of the coronavirus disease 2019 (COVID-19). The adverse effect following vaccination is an important consideration. Acute myocardial infarction (AMI) is a kind of rare adverse event after COVID-19 vaccination. Herein, we present a case of an 83-year-old male who suffered cold sweat ten minutes after the first inactivated COVID-19 vaccination and AMI one day later. The emergency coronary angiography showed coronary thrombosis and underlying stenosis in his coronary artery. Type II Kounis syndrome might be a potential mechanism, which is manifested as coronary thrombosis secondary to allergic reactions in patients with underlying asymptomatic coronary heart disease. We also summarize the reported AMI cases post COVID-19 vaccination, as well as overview and discuss the proposed mechanisms of AMI after COVID-19 vaccination, thus providing insights for clinicians to be aware of the possibility of AMI following COVID-19 vaccination and potential underlying mechanisms.

Prebunking can be used to pre-emptively refute conspiracy narratives. We developed a new approach to prebunking - fighting fire with fire - which introduces a plausible 'meta-conspiracy' suggesting that conspiracy theories are deliberately spread as part of a wider conspiracy. In two preregistered intervention studies, prebunking specific COVID-19 vaccine (Study 1, N = 720) and climate change (Study 2, N = 1077) conspiracy theories (e.

Since its discovery in the late 18th Century, the role of vaccination in preventing death and disease has expanded across many infectious diseases and cancer. Key to our understanding of vaccine immunogenicity and efficacy is knowledge of the immune system itself. Inborn Errors of Immunity (IEI) represent a heterogeneous group of disorders characterised by impaired function of the immune system.

Young adults in their 20s have shown slower uptake of COVID-19 vaccines relative to older adults, potentially endangering themselves and their communities. Despite this, little vaccine communication has specifically targeted this age group. This study explored why "20-somethings" in British Columbia (BC), Canada delayed COVID-19 vaccination, and how to better encourage their vaccine uptake.

Background: COVID-19 is still a significant health concern worldwide. B cell responses to COVID-19 have been extensively studied in acute severe disease, but less so during extended follow-up or mild disease. Persisting immunological changes together with herpesvirus reactivations during acute COVID-19 have been suggested as contributing factors for post-acute sequelae of COVID-19 (PASC).

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is capable of infecting multiple species through human-to-animal spillover. Human to animal spillovers have been documented both in domestic and wild animal species. Due to close contact in shared households, pet dogs may be at increased risk for contracting the SARS-CoV-2 virus from infected individuals in the same household.
