This study focuses on cardiovascular effects, particularly myocarditis and pericarditis events, after BNT162b2 mRNA COVID-19 vaccine injection in Thai adolescents. This prospective cohort study enrolled students from two schools aged 13–18 years who received the second dose of the BNT162b2 mRNA COVID-19 vaccine. Data including demographics, symptoms, vital signs, ECG, echocardiography and cardiac enzymes were… Continue reading Cardiovascular Effects of the BNT162b2 mRNA COVID-19 Vaccine in Adolescents

Covid-19: Regulators warn that rare Guillain-Barré cases may link to J&J and AstraZeneca vaccines
Rapid Response:Autoimmune damage to the nerves following Covid vaccines: EMA issued warning to patients and healthcare professionalsDear EditorEMA recently investigated the cases of Guillain-Barre syndrome (GBS) following Covid vaccine AstraZeneca (AZ) and have issued a warning to raise awareness of healthcare professionals and the public about GBS cases following Covid vaccinations and recommended revising the… Continue reading Covid-19: Regulators warn that rare Guillain-Barré cases may link to J&J and AstraZeneca vaccines
Immune boosting by B.1.1.529 (Omicron) depends on previous SARS-CoV-2 exposure
Importance of infection historyA long-term study of healthcare workers in the United Kingdom has allowed their history of infection and vaccination to be traced precisely. Reynolds et al. found some unexpected immune-damping effects caused by infection with a heterologous variant to the latest wave of infection by the Omicron/Pango lineage B.1.1.529. The authors found that… Continue reading Immune boosting by B.1.1.529 (Omicron) depends on previous SARS-CoV-2 exposure
The Incidence of Myocarditis and Pericarditis in Post COVID-19 Unvaccinated Patients—A Large Population-Based Study
Myocarditis and pericarditis are potential post-acute cardiac sequelae of COVID-19 infection, arising from adaptive immune responses. We aimed to study the incidence of post-acute COVID-19 myocarditis and pericarditis. Retrospective cohort study of 196,992 adults after COVID-19 infection in Clalit Health Services members in Israel between March 2020 and January 2021. Inpatient myocarditis and pericarditis diagnoses… Continue reading The Incidence of Myocarditis and Pericarditis in Post COVID-19 Unvaccinated Patients—A Large Population-Based Study
Risk of covid-19 related deaths for SARS-CoV-2 omicron (B.1.1.529) compared with delta (B.1.617.2): retrospective cohort study
Objective To assess the risk of covid-19 death after infection with omicron BA.1 compared with delta (B.1.617.2).Design Retrospective cohort study.Setting England, United Kingdom, from 1 December 2021 to 30 December 2021.Participants 1 035 149 people aged 18-100 years who tested positive for SARS-CoV-2 under the national surveillance programme and had an infection identified as omicron BA.1 or… Continue reading Risk of covid-19 related deaths for SARS-CoV-2 omicron (B.1.1.529) compared with delta (B.1.617.2): retrospective cohort study
The Problem of Home Therapy during COVID-19 Pandemic in Italy: Government Guidelines versus Freedom of Cure?
After starting in late 2019, COVID-19 spread worldwide, and Italy was one of the first Western nations to be seriously affected. At that time, both the virus and the disease were little known and there were no Evidence-Based Medicine indications for treatment. The Italian Health Ministry guidelines claimed that, unless oxygen saturation fell to <92%,… Continue reading The Problem of Home Therapy during COVID-19 Pandemic in Italy: Government Guidelines versus Freedom of Cure?
Update: COVID-19 Vaccine Candidates and Abortion-Derived Cell Lines
Accurate information about the development and production of COVID-19 vaccines is essential, especially because many proposed candidates use newer molecular technologies for production of a viral vaccine. One concern regarding the ethical assessment of viral vaccine candidates is the potential use of abortion-derived cell lines in the development, production or testing of a vaccine. This… Continue reading Update: COVID-19 Vaccine Candidates and Abortion-Derived Cell Lines
Vaccine mRNA Can Be Detected in Blood at 15 Days Post-Vaccination
COVID-19 mRNA vaccines effectively reduce incidence of severe disease, hospitalisation and death. The biodistribution and pharmacokinetics of the mRNA-containing lipid nanoparticles (LNPs) in these vaccines are unknown in humans. In this study, we used qPCR to track circulating mRNA in blood at different time-points after BNT162b2 vaccination in a small cohort of healthy individuals. We… Continue reading Vaccine mRNA Can Be Detected in Blood at 15 Days Post-Vaccination
Effects of wearing FFP2 masks on SARS-CoV-2 infection rates in classrooms
Importance: Different mitigation measures are mandated in schools worldwide to control the spread of SARS-CoV-2. The efficacy of most measures, however, has not been investigated thus far. Objective: To investigate the usefulness of FFP-2 masks in classrooms to prevent the spread of SARS-CoV-2. Design: A retrospective comparative cohort study of infection rates (evaluated by PCR… Continue reading Effects of wearing FFP2 masks on SARS-CoV-2 infection rates in classrooms
