Dr Byram Bridle

Dr. Byram Bridle is an Associate Professor of Viral Immunology in the Department of Pathobiology at the University of Guelph.

His research program focuses on vaccine development for the prevention of infectious diseases and to treat cancers with the goal of translating findings into humans. He also studies fundamental aspects of immune response to viruses. Dr. Bridle received funding from the Ontario Government and the Government of Canada for pre-clinical development of vaccines against coronaviruses. He holds no commercial interests in his COVID-19-focused research. Dr. Bridle holds numerous grants for research into cancers and viral immunology. Since the COVID-19 pandemic was declared, he has been actively involved in providing fact-based answers to questions posed by the public to help them make fully informed decisions about their health. This has included ~250 media engagements ranging from radio shows, published articles, and appearances on televised news programs (including, but not limited to, W5, The West Block, CTV National News, and Fox News), spanning the local to international scope. He was also an invited keynote speaker for two international conferences about COVID-19, and has served as an invited member of numerous COVID-19-focused discussion panels.

Dr. Bridle has an excellent track record of following the science underpinning COVID-19 vaccines and predicting where this will lead. Here are two examples: Example #1. When Health Canada authorized the use of AstraZeneca’s vaccine, Dr. Bridle, along with two colleagues, wrote an open letter requesting that this vaccine not be used, in part on the grounds that it was being investigated for a link to potentially fatal blood clots in many European countries. Less than two months later, Canada suspended the AstraZeneca vaccination program, because it was deemed to be too unsafe because of causing blood clots that cost the unnecessary loss of lives of Canadians. Example #2. In May 2021 Dr. Bridle publicly raised concerns about a potential link between mRNA-based COVID-19 vaccines and heart inflammation in young people, especially males due to his knowledge of an alarming biodistribution pattern for these vaccines. This is now a well-recognized problem that has been officially listed as a potential side-effect of the mRNA COVID-19 vaccines. It was also the subject of a recent Public Health Ontario Enhanced Epidemiological Summary Report highlighting the increased risk of myocarditis and pericarditis to young males following COVID-19 mRNA vaccination. Further, use of Moderna’s COVID-19 vaccine has been discontinued for this reason in young males in most of Canada. During the declared pandemic, Dr. Bridle has published thirty-three peer-reviewed papers in high-quality indexed scientific journals, including three that are solely focused on COVID-19. He has also served as an expert witness for scientific matters related to COVID-19 in the Ontario Supreme Court of Justice, in service of the Court of Queen’s Bench of Alberta, and for the High Court of New Zealand. His current messaging can be followed through 'Substack's COVID Chronicles' (
