Dr Byram W. Bridle PhD, a pro-vaxxer, virologist, says the science is clear, the spike protein is the toxin. It leads to all the reported adverse events, death from blood clots, Thrombosis with Thrombocytopenia Syndrome (also termed Vaccine-induced Thrombotic Thrombocytopenia), heart disease Myocarditis, bleeding disorders, miscarriages and many more. So injecting the COVID vaccines into people is a major mistake. The spike protein is a pathogenic toxin.
