Dr. explains that Covid was never isolated therefore no one knows what it really is

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.
