Published: June 2023

We present the case of a 41-year-old man who developed myopericarditis after receiving the Pfizer COVID-19 vaccine. The patient experienced a sudden onset of chest and abdominal pain 16 days after vaccination. Electrocardiogram findings revealed deep T-wave inversion and minimal ST-segment elevation. Further investigation through coronary artery angiography and computed tomography identified an anomalous left main coronary artery. Magnetic resonance imaging confirmed the diagnosis of myopericarditis. This case highlights the importance of considering myopericarditis as a potential cause of chest pain and elevated cardiac biomarkers following COVID-19 vaccination, particularly in young individuals. Clinicians should be aware of this adverse event and include it in the differential diagnosis for patients presenting with similar symptoms after vaccination.

Background: Since 2021, COVID-19 has had a substantial impact on global health and continues to contribute to serious health outcomes. In Taiwan, most research has focused on hospitalized patients or mortality cases, leaving important gaps in understanding the broader effects of the disease and identifying individuals at high risk. This study aims to investigate the risk factors for disease progression through a nationwide population-based cohort study on COVID-19 in Taiwan.

Porcine epidemic diarrhoea virus (PEDV) is a porcine enteric coronavirus, outbreaks and epidemics of which have caused huge economic losses to the livestock industry. The disadvantage of existing PEDV vaccines is that the unstable efficacy and high cost limit their widespread use. Therefore, there is an urgent need to develop a recombinant transgenic vaccine candidate for PEDV.

Emerging infectious disease agents represent pathogens that may evade current screening protocols while posing significant transfusion transmission risks regionally. This study investigated the prevalence of SARS-CoV-2 and other respiratory viruses among 633 blood donors at the MT-Hemocentro from November 2021 to February 2023. Nucleic acid obtained from nasopharyngeal swabs were tested by RT-qPCR for SARS-CoV-2, RSV, FLU-A, and FLU-B.
