Navigating the Lab-Leak Theory: Implications and Actions Needed
Written on
Chapter 1: Rethinking Research Safety
Last summer, Michael Imperiale, a virologist at the University of Michigan and a seasoned member of the National Science Advisory Board for Biosecurity, published an essay advocating for a reassessment of essential research safety protocols in light of the coronavirus pandemic. However, he and his co-author wanted to clarify that there was no evidence to suggest that negligent or malevolent scientific practices contributed to the emergence of the SARS-CoV-2 virus; to imply otherwise is more akin to conspiracy theories than scientifically sound reasoning.
As of nine months later, Imperiale's perspective has evolved slightly. "While I still believe the bulk of evidence supports a natural origin," he mentioned in a recent discussion, "the gap between natural and lab-origin evidence seems to be narrowing."
The growing skepticism surrounding COVID-19’s origin—whether the virus jumped from bats or other wildlife directly or if it escaped from a laboratory in Wuhan, China—has recently escalated. In just the past fortnight, sentiments have shifted among leading biosafety experts, public health officials, commentators, and journalists from prominent publications. The World Health Organization's (WHO) February assertion that a lab-leak origin was "extremely unlikely" has faced criticism from WHO director general Tedros Ghebreyesus. A May 14 letter in Science signed by 18 scientists called for a "proper investigation" and emphasized the need for "science-based discourse on this complex yet vital issue." Furthermore, David Frum suggested in The Atlantic that the Biden administration should "uncover the truth about the virus," while Nate Silver increased his estimate of a laboratory origin to 60 percent. President Joe Biden recently stated that the U.S. intelligence community is still undecided about which hypothesis is more probable and expressed a desire for a "closer determination" by the end of August.
The shift in perspective is striking, especially given the absence of groundbreaking revelations. Arguments supporting the lab-leak hypothesis remain anchored in the concerning fact that a coronavirus likely linked to bats appeared abruptly in a city far removed from where researchers had been studying these viruses. This raises essential questions about the origins of the outbreak. The increasing acceptance of the lab-leak theory, despite the lack of new evidence, suggests that definitive proof may not be strictly necessary. Given that the SARS-CoV-2 outbreak has led to millions of deaths, it is crucial to recognize that the possibility of a lab-related origin exists, and we must act on this assumption.
According to the aforementioned letter to Science, understanding how COVID-19 originated is vital for shaping global strategies aimed at reducing the risk of future outbreaks.
"Catching the origins of COVID-19 is essential for minimizing future pandemics," noted the letter.
Section 1.1: Urgency in Addressing COVID-19's Origins
Most articles and discussions about the lab-leak theory include a statement underscoring its importance. Questions surrounding whether COVID-19 originated from wildlife or escaped from a lab are crucial for preventing future pandemics. As one article from March stated, "This urgent question is key to preventing the emergence of a SARS-CoV-3 or a COVID-29."
Subsection 1.1.1: The Complexity of Pandemic Origins
Another commentary emphasized, "Understanding how a virus-driven pandemic begins is crucial for averting similar situations in the future." However, this viewpoint raises a fundamental question: Does knowing the precise origin of SARS-CoV-2 significantly influence our ability to devise policies to prevent future outbreaks? It risks committing us to hindsight bias, focusing too heavily on the past rather than preparing for emerging threats.
What insights could a "proper investigation" yield? At most, it might pinpoint additional locations for studying natural spillovers or identify new types of lab accidents. While this information is valuable, it merely adds one more case study to a limited set. Throughout the past century, most pandemics have natural origins, with just a few potentially linked to lab accidents.
Rather than calling for an extensive investigation into origins, we should accept that pandemics can arise from both natural spillovers and laboratory accidents, then focus on the implications. One pressing concern has emerged: Should scientists be manipulating pathogenic genomes to assess risks before they escalate to pandemic levels? This topic has sparked intense debates among virologists since 2012, with ongoing uncertainty about the benefits and risks of such research.
Other critical questions include: Should wild coronavirus samples be studied under moderate biosafety levels, as suggested by the practices at the Wuhan Institute of Virology? Is there a significant drawback to implementing stricter safety regulations for surveillance work? And should China cease transporting virus-laden guano from remote areas to urban centers, as appears to have happened in Wuhan? Furthermore, discussions arise about whether studies on pathogens like Ebola should be conducted in Boston.
As Alina Chan, a molecular biologist at the Broad Institute, pointed out recently, we may find that the COVID-19 narrative is akin to "a small-town virus brought to the city and suddenly becoming a star."
Section 1.2: The Broader Implications of Research Safety
We may require a more comprehensive inquiry into the risks associated with scientific research. Recognizing that a lab-origin pandemic is plausible necessitates understanding that future public health threats could arise from various biological sources—be it crop destroyers, ocean changes, or atmospheric shifts. Sam Weiss Evans, a biosecurity governance scholar, remarked, "This could serve as a wake-up call for the broader biological community."
However, these discussions are currently stalled as scientists pursue an exhaustive examination of the lab-leak theory, which may ultimately prove fruitless. They do not exhibit the same level of scrutiny regarding the "spillover" hypothesis, which also lacks direct evidence in the case of COVID-19. David Relman, a microbiologist at Stanford University and one of the authors of the Science letter, stated that the research community already acknowledges the occurrence of natural spillovers leading to dangerous outbreaks, which does not require additional proof.
Relman does not anticipate a similar proactive approach toward laboratory safety. He noted that many scientists find the idea of a lab accident causing a pandemic uncomfortable and challenging to accept. Without compelling evidence supporting the lab-leak hypothesis, he believes, "People will continue to express concerns but may not take significant steps to mitigate risks."
More specific evidence might never materialize, even with further investigations by the CIA or WHO. A "proper investigation" could ultimately be counterproductive. What if it continues indefinitely without yielding concrete findings? Or what if researchers establish that SARS-CoV-2 indeed originated in animals? Such outcomes would not eliminate the risk of lab leaks, yet they could diminish the scientific community's urgency to address the issue.
"There is a possibility of a lab escape," Imperiale stated, emphasizing the need for action regardless. "We must avoid asking the same questions a decade from now." At this stage, calls for further investigation could hinder rather than facilitate progress.
