Andrew Kaufman, MD, interviewed by Del Bigtree, delivers an excellent short course on the risks of Covid tests and vaccines. The Interview is preceded by a short clip from an NBC report on 2021 January 23 in which China’s Chief epidemiologist, Dr. Wu Zunyou, says: "They didn't isolate the virus, and that is the problem.” Dr. Kaufman explains why that means there is no proof that a Covid-19 virus even exists and, instead, could be merely a variant of the common flu. This interview includes a summary of the debate between advocates of the germ theory and the terrain theory of disease. Be prepared for a deep dive into concepts and dogma that seldom are discussed but which are critical to disease control. 2020-07-20 - Source: Andrew Kaufman - https://youtu.be/06hFyHaivHc
