It’s been almost two years since COVID-19 struck, and the origin of the virus remains a mystery. Did the virus jump from animals to humans in a natural spillover event, or was it the result of a laboratory leak? A new book explores these and other questions on the source of the coronavirus that has killed more than 5 million people worldwide to date.
“That is not where either of us started. We began thinking that it was probably a natural spillover event, and gradually, as the evidence accumulated in favour of a lab leak and against a wildlife market event, we’ve come to the conclusion that that is slightly more probable.”
“Even the U.S. Intelligence Community has said that a lab origin is a plausible origin of COVID-19,” she said at the webinar, hosted by Ottawa-based Macdonald-Laurier Institute.
Chan said proponents of the natural origin theory failed to find any direct evidence that the virus crossed from animals to humans and caused the pandemic that began engulfing the world in early 2020.
“The Chinese scientists who have been sampling 80,000 animal samples have told us they have found no trace of SARS2-like viruses,” she said.
Gain-of-Function Research
Ridley said the World Health Organization (WHO) acted under the influence of Beijing in the early stages of the pandemic and ignored warnings from Taiwan that the virus could spread from human to human.When a WHO team travelled to Wuhan in January 2021 to conduct an investigation, they followed the direction of the Chinese regime, he said, even holding a press conference endorsing the “ludicrous” suggestion from Chinese scientists that the virus arrived in Wuhan via frozen food, “magically failing to infect anyone in the source country or the source farm or along the way or in any other city’s wet markets.”
Ridley said even though he and Chan lean toward the possibility that a virus of natural origin was brought to the lab “and then leaked out through an incident,” they are inclined to think that the virus “may well have been engineered before it was released.”
He said they came across documents from 2018 that detailed how EcoHealth Alliance, a U.S. based non-profit health organization, had planned to collaborate with the Wuhan Institute of Virology (WIV) to “essentially make them [novel coronaviruses] easier to grow in human cells in the laboratory so as to be able to study them better.”
“The application was ultimately unsuccessful, but its contents laid bare their extensive roadmap for collecting and experimenting with SARS-like viruses with pandemic potential,” the authors wrote.
Daszak’s proposal was rejected on the grounds that “although the approach potentially involved gain-of-function research, it did ‘not mention or assess potential risks of Gain of Function (GoF) research and DURC [Dual Use of Research Concern].’”
“It was revealed that by that time, the EcoHealth Alliance and its collaborators had already found more than 180 unique SARS-like viruses across approximately ten thousand samples,” the authors wrote.
“In other words, this early 2018 proposal told us that the EcoHealth Alliance and WIV were in possession of a growing semi-private collection of SARS-like viruses; they had intended to expand their recombinant virus infection experiments across a range of cells and animals; they had also delineated a workflow for identifying novel cleavage sites and inserting these into novel spikes and novel SARS-like viruses in the lab.”
Chan said GoF research, which seeks to increase the transmissibility or the severity of disease caused by a pathogen so that “you can predict how wild natural viruses can evolve to spill over and cause pandemics,” doesn’t pay off.
“When you weigh the risks versus benefits, the risk of creating dangerous pathogens in the lab is that they could leak and actually cause a pandemic, whereas the benefits are really unclear,” she said.
Ridley said lab leaks have occurred over the years even from laboratories designated as biosafety level 4—the highest level of biological safety.
He said the lab leak hypothesis can easily be disproved if China is willing to be transparent about the work being done at WIV at the time of the virus outbreak.
“All they have to do to disprove that is open their files and show us exactly which samples of which viruses they were dealing with in the laboratory—all of their sequences, all of their histories, where they came from, and what experiments were done with them.”
