TL;DR

US government's DEEP VZN project, aimed at finding dangerous viruses, was halted due to catastrophic risk concerns.

Key Insights

1

The DEEP VZN program aimed to discover and characterize potentially pandemic-grade viruses from remote locations.

2

The program's core activities involved 'virus hunting,' genetic characterization, and open publication of findings and virus genomes.

3

Critics argued that collecting and studying dangerous viruses in leaky labs increases the risk of accidental release or weaponization.

4

The open publication of virus genomes could equip thousands of unvetted individuals with the means to create bioweapons.

5

A concerted whistleblowing effort involving public figures, scientists, and policymakers successfully pressured the US government to halt the program.

6

While DEEP VZN was stopped, the underlying risks of bioweapons development, exacerbated by AI, persist globally.

THE ORIGINS OF CONCERN: BIORISK AND DEEP VZN

Rob Reid discusses his decade-long focus on biorisk, stemming from writing a science fiction novel that featured a synthetic biology-based pandemic. This personal exploration led to a TED talk and collaborations, eventually bringing him into contact with the US government's Agency for International Development (USAID). A startling discovery within USAID was the DEEP VZN program, a $125 million, five-year initiative with the stated intention of improving global biosecurity but which a prominent expert described as having the potential to 'cancel civilization.'

DEEP VZN'S THREE DANGEROUS PROPOSITIONS

DEEP VZN was built upon three core, risky ideas. Firstly, 'virus hunting' involved collecting up to 10,000 undiscovered viruses from remote locations like bat caves and bush meat markets in developing countries, bringing them into densely populated areas for study. Secondly, 'characterization' aimed to identify which of these viruses were most likely to be pandemic-grade, a process that could inadvertently highlight potential bioweapons. Finally, the program planned to publish the genomes of these dangerous viruses openly, effectively distributing bioweapon blueprints globally.

THE INHERENT RISKS OF VIRUS COLLECTION AND CHARACTERIZATION

The practice of 'virus hunting' and subsequent genetic 'characterization' carries significant risks. Laboratories, even at the highest biosafety levels, are known to leak, and there is no standardized reporting system to track these incidents. Bringing potentially deadly pathogens into these 'leaky vessels' in populated areas is more dangerous than them remaining in isolated natural environments. Furthermore, identifying 'pandemic grade' viruses doesn't offer practical benefits like vaccine development without live testing, which is ethically impossible for deadly pathogens. Instead, it creates a list of highly dangerous viruses that could attract unwanted attention from nefarious actors.

OPEN PUBLICATION: ARMING POTENTIAL ADVERSARIES

The most alarming aspect of DEEP VZN was its intention to publish the genomes of dangerous viruses discovered and characterized. At the time, an estimated 30,000 individuals worldwide possessed the technical skills and knowledge to synthesize these viruses from scratch using techniques like reverse genetics. This plan would have effectively granted near-nuclear-arsenal-level destructive power to thousands of unvetted individuals globally, potentially including those in unstable regions or with malicious intent, thereby democratizing bioweapon creation to an unprecedented degree.

THE WHISTLEBLOWING CAMPAIGN AND PROGRAM HALT

Upon learning of DEEP VZN, Rob Reid collaborated with Sam Harris to raise public awareness through a podcast episode, specifically targeting then-USAID administrator Samantha Power. Despite initial silence, a broader coalition, including figures like Tristan Harris, Daniel Schmokenberger, and organizations like Helena (with Pro Basu playing a key role), emerged. Pressure mounted through bipartisan efforts, including actions by Senators Lindsey Graham, James Risch, and Rand Paul, leading to the program being effectively defanged and eventually formally terminated in September 2023, removing a significant source of plausible bioweapon risk.

THE PERSISTENT THREAT IN A CHANGING LANDSCAPE

While DEEP VZN was successfully dismantled, the fundamental threat remains. Other nations, like China's Wuhan Institute of Virology, have engaged in similar virus collection efforts, and past US-funded programs like Predict also collected vast numbers of viruses. Crucially, advancements in artificial intelligence are significantly accelerating the potential for bioweapon development. The ability to synthesize dangerous pathogens from publicly available genetic information, a capability highlighted by the publication of the 1918 flu genome, is now far more accessible, posing an escalating global security challenge.

Common Questions

Deep Vision was a USAID-authorized program with a $125 million budget aimed at discovering and studying novel viruses. It was controversial because its three main components—virus hunting in remote areas, characterizing deadly viruses, and publishing their genomes—were seen as creating extreme biosecurity risks, potentially empowering individuals to create bioweapons.
