evidence: No scientific evidence supports McCullough’s claim that the spike protein exposure induced by COVID-19 vaccination is toxic, as Health Feedback explained in earlier reviews. As others did before, McCullough misinterpreted the results of studies that evaluated the effect of the viral spike protein, not the one induced by vaccination. [...] After spending the interview enumerating the wide range of harmful effects that COVID-19 vaccines allegedly cause, McCullough talked about a dietary supplement supposedly capable of countering them all. This supplement contained nattokinase, an enzyme that was first isolated from a traditional Japanese dish called natto and made of fermented soybeans. [...] No evidence suggests that the spike protein induced by COVID-19 vaccination is toxic. McCullough’s claims that COVID-19 vaccines caused a rise in mortality and medical conditions are also unsupported by scientific evidence. Instead, studies show that COVID-19 vaccines are safe and effective at preventing severe COVID-19 and death.
