Part 3/11:
Kaufman, who has been at the forefront of the scientific skepticism movement regarding COVID-19, insists on examining whether SARS-CoV-2, the virus purported to cause COVID-19, has ever actually been isolated and characterized in a way that fulfills Koch's postulates—the criteria established for proving a causal relationship between a pathogen and a disease.
He notes that a large body of published studies continues to present claims about the virus's existence and pathogenicity, but what he finds repeatedly is a lack of substantial, replicable evidence. Instead of genuine proof of isolation and causality, Kaufman suggests that what has been presented as scientific fact often resorts to theory-laden claims based on incomplete and potentially misleading studies.
