Emerging advances in artificial intelligence (AI) raise growing concerns about the potential acceleration of biological weapons development, underscoring the need for enhanced national biosecurity measures. Researchers demonstrated last year that AI systems could design hundreds of novel virus genomes, including some capable of producing viable viruses that infect and kill bacteria more effectively than their natural counterparts. While these viruses are not infectious to humans and the study was not weapon-focused, the findings highlight how AI could theoretically be used to create dangerous pathogens with relative ease by skilled actors.
Following these developments, a symposium held in Washington in January brought together biosecurity experts and former defense officials to assess the national security implications of rapid pathogen design powered by AI. Participants expressed concern that society is entering a new era where AI can engineer pathogens faster than existing capabilities allow for the development of countermeasures such as vaccines, antibodies, antivirals, and diagnostics. This imbalance is particularly alarming given the challenges posed by opaque actors, illustrated by recent controversies surrounding Russia’s anti-plague research facilities.
Experts argue that the United States needs to establish a standing, well-funded initiative akin to the scale and urgency of Operation Warp Speed, which expedited COVID-19 vaccine development. Unlike the emergency-driven program launched in 2020, a permanent biosecurity infrastructure would maintain continuous capacity for research, manufacturing, and rapid response to biological threats. Such a program would require bipartisan Congressional support and legal mandates to ensure its longevity across administrations.
Currently, Senate legislation introduced by Senators Tom Cotton and Amy Klobuchar aims to reduce the risk of misuse by requiring synthetic DNA providers to screen orders for sequences that might be used to create biological threats. While seen as a proactive step, the bill addresses prevention rather than rapid response if a bioweapon were to be deployed. Experts warn that this approach is insufficient because a single failure in screening could lead to catastrophic consequences.
The widely endorsed goal of developing a vaccine within 100 days of detecting a new pandemic pathogen reflects preparations predicated on natural outbreaks, which typically emerge from identifiable animal reservoirs and locations. AI-engineered pathogens challenge these assumptions, as early indications may only be clinical illness, leaving significantly less time to study the virus and deploy countermeasures. By the time vaccines reach the 100-day benchmark, such a pathogen could have already caused widespread devastation.
On a positive note, advancements in AI may also expedite countermeasure design. The same tools capable of rapidly generating viral genomes can be applied to develop antibodies and antigens, potentially reducing development times from months to hours in the near future. The challenge lies in sustaining infrastructure and manufacturing capabilities during periods without active threats, as private pharmaceutical markets lack incentives to maintain readiness for non-existent pathogens.
Experts recommend a comprehensive biosecurity system that supports multiple biotechnology platforms and maintains continuous manufacturing capacity. Regular drills testing vaccine readiness against hypothetical viral genomes could ensure operational effectiveness, mirroring preparedness protocols used in other national defense sectors such as nuclear deterrence.
Unlike nuclear weapons, biological threats currently lack binding international treaties or robust defense systems. As the possibility of AI-facilitated biological attacks grows, government-led initiatives to build, test, and maintain a rapid countermeasure capability are increasingly seen as essential to national security.
