Jon Rappoport explains in LewRockwell.com that there is no such thing as an un-mutated virus. He writes (abridged):
David Rasnick , PhD chemist, with a long history working in the pharmaceutical industry (Abbott, Prototek, Arris), broke away from official science and served as the president of Rethinking AIDS: the group for the scientific reappraisal of the HIV hypothesis. He was a member of the Presidential AIDS Advisory Panel of South Africa.
Here is a recent explosive statement Rasnick made  about SARS-CoV-2 and HIV. Digesting it brings about a breakthrough revelation:
Viruses are unstable, RNA [e.g, SARS-Cov-2] viruses especially. They are so unstable, there is no such thing as an un-mutated RNA virus. They are like snow flakes, no two are identical.”
“HIV is an RNA virus with 9,800 nucleotides. You can download the HIV Sequence Compendium here:” 
“In the Preface it says:”
“’The number of [genetic] sequences in the HIV database is still increasing. In total, at the end of 2017, there were 812,586 sequences in the HIV Sequence Database, an increase of 8.5% since the previous year.”
“None of the sequences of the world destroying [sarcasm], computer generated coronavirus with its 30,000 or so nucleotides, are identical.”
“The virus maniacs use computers to compare the menagerie of sequences to come up with ‘A Consensus Sequence’ for HIV, Coronavirus, and all the rest. The consensus sequence exists in two places: in computers and in strings of RNA synthesized in the lab.”
“Even consensus sequences are not stable. Different groups, using a variety of computer algorithms will invariably come up with different ‘consensus sequences’.”
[A]s I’ve reported these past few months, there is every reason to doubt and reject the existence of the COVID virus, since correct large-scale electron microscope studies have never been done.
I kept the Christine Johnson interview, and other similar information, in mind when, for example, I explored the dud epidemics called SARS and 2009 Swine Flu.
How many viruses have been named as causes of disease, when in fact those viruses have never been isolated or proved to exist?
Of course, conventional-consensus researchers and doctors will scoff at any attempt to raise these issues. For them, “the science is settled.” Meaning: they don’t want to think. They don’t want to stir the waters.
A few years ago, chemist David Rasnick sent a request to the CDC, asking for evidence demonstrating that the Ebola virus had ever been isolated from a human. The answers he received did not begin to approach a level of certainty.
After 30 years working as a reporter in the area of deep medical-research fraud, I’ve seen that false science occurs in levels.
The deeper you go, the stranger it gets. To put it another way: the deeper you go, the worse it gets.
