Scientists that believe COVID-19 may have an unnatural origin

…the 2019-nCoV data are consistent with entry into the human population as either a natural accident or a laboratory accident.

…the fact that SARS-CoV-2 doesn’t have the same RBD amino acid sequence as the one that the computer program predicted in no way rules out the possibility that it was genetically engineered.

SARS-CoV-2 could have spent some time in a laboratory before encountering humans…All scientists need to acknowledge a simple fact: Humans are fallible, and laboratory accidents happen — far more often than we care to admit.

Distinguished Service Professor Emeritus of Virology, University of Chicago

I’m convinced that what happened is that the virus was brought to a lab, they started to work with it…and some sloppy individual brought it out, …They can’t admit they did something so stupid.

…within the SARS-CoV-2 genome there is an insertion of 12 nucleotides that is entirely foreign to the beta-coronavirus class of virus that SARS-CoV-2 is in…


…you want to know were there people in the virology laboratory in Wuhan who were manipulating viral genetic sequences? It’s really a question of history: What happened?


…it seemed to me a reasonable hypothesis that somebody had put it in there. Now, I don’t know if that’s true or not, but I do know that it’s a hypothesis that must be taken seriously.

Spike protein exhibited the highest binding to human (h)ACE2 of all the species tested. These findings show that the earliest known SARS-CoV-2 isolates were surprisingly well adapted to bind strongly to human ACE2, helping explain its efficient human to human respiratory transmission.

Robert Redfield
former Director of The Centers for Disease Control and Prevention

I am of the point of view that I still think the most likely etiology of this pathogen in Wuhan was from a laboratory, you know, escaped.

The potential for conspiracy is really on the other side. The conspiracy is Collins, Fauci, and the established scientific community that has acted in an antithetical way to science.

I think a lab origin is more likely than a natural origin at this point.

In fact, the assertion that the FCS in SARS-CoV-2 has an unusual, nonstandard amino acid sequence is false. The amino acid sequence of the FCS in SARS-CoV-2 also exists in the human ENaC α subunit, where it is known to be functional and has been extensively studied.

SARS-CoV-2 is either an evolutionary anomaly or a chimera, since no other sarbecovirus has a furin cleavage site. If an anomaly, why did it emerge in a city with a lab working on bat coronaviruses? The lab had grant proposals to insert such sites, favoring the chimera hypothesis.

So I think that molecular biologists have by accident caused a planetary disaster. It is of the utmost importance to have regulations that help prevent this happening again.

It would be a one-in-a-million, one-in-a-billion chance that it came out of an animal able to infect humans at this rate.

At present, there is, I believe, no evidence of a zoonotic chain linking bats to Wuhan, but there is clear evidence that SARS-COV-2 is probably a product of genetic manipulation.

It was the moment for me when the possibility that the furin cleavage site was engineered went from a seemingly low possibility to a completely plausible possibility.

Don Newmeyer
Emeritus Professor for Allergy and Immunology at La Jolla Institute

Absolutely, the viral genome sequence is a smoking gun for lab manipulation. Add to that the other circumstantial evidence (EcoHealth and Ralph Baric and DOD grant applications, etc), plus the ease of lab accident, it’s obvious.

My view is that it’s almost 100% likely COVID originated from the Wuhan lab – as it has been for some time. We’ve witnessed essentially a cover up from large parts of the international medical community. The question is now not what was covered up, but why it was covered up?
