Canadian molecular biologist Dr Alina Chan has informed the members of Parliament (MPs) on the House of Commons Science and Technology Committee on Wednesday that a leak from a laboratory in Wuhan region of China is now the “more likely” origin of the COVID-19 global pandemic.
Dr Chan who has specialised in gene therapy and cell engineering and co-authored the book ‘Viral: The Search for the Origin of COVID-19′, told the all-party Parliament panel’s evidence session on scientific research that the pandemic was being caused by the unique feature of the coronavirus called “furin cleavage site”, which has been linked to the Wuhan Institute of Virology.
Replying to a question by the panel about the probability of a lab leak as the origin of the pandemic, Dr. Chan said a “lab origin is more likely than natural origin at this point”. “We all agree that there was a critical event at the Huanan Seafood Market, that was a superspreader event caused by humans. There is no evidence pointing to a natural animal origin of the virus at that market,” she said.
On the question of her level of confidence that the world would eventually be able to establish the true origins of COVID-19, Chan said it was simply a matter of time. “Right now it’s not safe for people who know about the origin of this pandemic to come forward. It might be five years from now, it might be 50 years from now, but we live in an era where there’s so much data being collected and stored…we just need a credible, systematic investigation,” she said.
On whether the virus was modified in the lab before a leak, Chan said: “We have heard from many top virologists that a genetically engineered origin of this virus is reasonable…and this includes virologists who themselves have made modifications to the first SARS virus. “We know now that this virus has a very unique feature, called the furin cleavage site that makes it the pandemic pathogen it is. So, without this feature, there’s no way this would be causing this pandemic”, she stressed.
Her co-author, Lord Matt Ridley, was also asked similar questions about the lab leak theory and he concurred with Chan’s assertion that it was “more likely than not” the cause behind the pandemic.
“We have to face the fact that after two months we knew the origins of SARS through markets, and after a couple of months we knew the origin of MERS through camels. In this case, after two years we still haven’t found a single infected animal that could be the progenitor of this pandemic; that’s extremely surprising,” he said.
Ridley, along with Chan, agreed that any leak was most likely an “accident” as he traced the journey of scientists a few years ago to bring SARS-like viruses back to Wuhan for experiments.
