Censorship and Suppression of Covid-19 Heterodoxy: Tactics and Counter-Tactics
The emergence of COVID-19 has led to numerous controversies over COVID-related knowledge and policy. To counter the perceived threat from doctors and scientists who challenge the official position of governmental and intergovernmental health authorities, some supporters of this orthodoxy have moved to censor those who promote dissenting views. The aim of the present study is… Continue reading Censorship and Suppression of Covid-19 Heterodoxy: Tactics and Counter-Tactics
Age-stratified infection fatality rate of COVID-19 in the non-elderly population
The largest burden of COVID-19 is carried by the elderly, and persons living in nursing homes are particularly vulnerable. However, 94% of the global population is younger than 70 years and 86% is younger than 60 years. The objective of this study was to accurately estimate the infection fatality rate (IFR) of COVID-19 among non-elderly… Continue reading Age-stratified infection fatality rate of COVID-19 in the non-elderly population
Pre-exposure to mRNA-LNP inhibits adaptive immune responses and alters innate immune fitness in an inheritable fashion
Hundreds of millions of SARS-CoV-2 mRNA-LNP vaccine doses have already been administered to humans. However, we lack a comprehensive understanding of the immune effects of this platform. The mRNA-LNP-based SARS-CoV-2 vaccine is highly inflammatory, and its synthetic ionizable lipid component responsible for the induction of inflammation has a long in vivo half-life. Since chronic inflammation can lead… Continue reading Pre-exposure to mRNA-LNP inhibits adaptive immune responses and alters innate immune fitness in an inheritable fashion
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
Apparent risks of postural orthostatic tachycardia syndrome diagnoses after COVID-19 vaccination and SARS-Cov-2 Infection
Postural orthostatic tachycardia syndrome (POTS) was previously described after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection; however, limited data are available on the relation of POTS with Coronavirus Disease 2019 (COVID-19) vaccination. Here we show, in a cohort of 284,592 COVID-19-vaccinated individuals, using a sequence–symmetry analysis, that the odds of POTS are higher 90 days… Continue reading Apparent risks of postural orthostatic tachycardia syndrome diagnoses after COVID-19 vaccination and SARS-Cov-2 Infection
SARS-CoV-2 antibodies persist up to 12 months after natural infection in healthy employees working in non-medical contact-intensive professions
This study aimed to evaluate dynamics of antibody levels after exposure to SARS-CoV-2 for 12 months in Dutch non-vaccinated hairdressers and hospitality staff.MethodsIn this prospective cohort study, blood samples were collected every 3 months for 1 year and analyzed using a qualitative total antibody enzyme-linked immunosorbent assay (ELISA) and a quantitative immunoglobulin (Ig)G antibody ELISA.… Continue reading SARS-CoV-2 antibodies persist up to 12 months after natural infection in healthy employees working in non-medical contact-intensive professions
Serious harms of the COVID-19 vaccines: a systematic review
Introduction Serious harms of the COVID-19 vaccines have been underreported in published trial reports.Methods Systematic review of papers with data on serious adverse events (SAEs) associated with a COVID-19 vaccine.Results We included 18 systematic reviews, 14 randomised trials, and 34 other studies with a control group. Most studies were of poor quality. The most reliable one was a… Continue reading Serious harms of the COVID-19 vaccines: a systematic review
The pharmaceutical industry is dangerous to health. Further proof with COVID-19
Background:The COVID-19 period highlights a huge problem that has been developing for decades, the control of science by industry. In the 1950s, the tobacco industry set the example, which the pharmaceutical industry followed. Since then, the latter has been regularly condemned for illegal marketing, misrepresentation of experimental results, dissimulation of information about the dangers of… Continue reading The pharmaceutical industry is dangerous to health.
