A tabletop exercise at the Munich Security Conference that simulated an engineered monkeypox bioterror attack — published 6 months before the real-world 2022 mpox outbreak, making it the "Event 201 of monkeypox."
View Evidence Cards Back to HubNTI partnered with the Munich Security Conference to simulate a catastrophic biosecurity scenario involving an engineered pathogen — with eerily prophetic timing.
The scenario depicted a bioterror attack using an engineered, more transmissible and more lethal strain of monkeypox virus. The attack originated in the fictional nation of "Brinia" and spread globally over 18 months, ultimately infecting 3.2 billion people and killing 271 million.
The NTI report was published in November 2021. In May 2022, an unprecedented multi-country mpox (monkeypox) outbreak emerged — the first sustained person-to-person transmission outside Africa. The exercise's scenario date for the initial attack was May 15, 2022 — within days of the real outbreak.
The exercise identified that the Biological Weapons Convention (BWC) — the 1972 treaty banning bioweapons — has no verification mechanism, no inspection regime, and no enforcement authority. A state-sponsored bioweapons program could operate with impunity. NTI recommended establishing an independent verification body.
When the fictional attack occurred, the international community had no capability to determine whether the pathogen was natural or engineered, or to attribute it to a state actor. Participants recommended creating a joint assessment mechanism under the UN Secretary-General.
NTI (Nuclear Threat Initiative) was founded in 2001 by former Senator Sam Nunn and Ted Turner to reduce nuclear threats. Their pivot to biological threats reflects the growing consensus that engineered pathogens now pose an existential risk comparable to nuclear weapons — but with far less governance infrastructure.
Participants included current and former heads of state, health ministers, intelligence officials, and biodefense experts from the U.S., Germany, China, India, the Czech Republic, and others. The exercise was moderated by NTI's Dr. Beth Cameron, former NSC Senior Director for Global Health Security.
The exercise scenario played out over three moves spanning 18 months.
An unusual outbreak of monkeypox is reported in the fictional nation of Brinia. Initial genome sequencing suggests the strain has been engineered for increased transmissibility. Cases appear simultaneously in multiple countries. WHO declares a Public Health Emergency of International Concern.
Intelligence confirms the outbreak was a deliberate bioterror attack by a Brinian terrorist group that obtained the pathogen from a lab with inadequate biosecurity. The engineered virus has a higher case fatality rate than natural monkeypox. Existing smallpox vaccines provide only partial protection.
The pandemic reaches its peak. 3.2 billion people have been infected. 271 million are dead. The global economy is devastated. The BWC has proven toothless. No attribution mechanism has been established. The world has no defense against the next engineered pathogen.
Senior biosecurity officials and former heads of state from across the globe.
The NTI report made 5 specific recommendations for strengthening global biosecurity systems.
The Biological Weapons Convention must be given a verification mechanism comparable to the IAEA for nuclear weapons. Current BWC has no inspections, no enforcement, and no authority to investigate suspected violations.
Establish an independent international mechanism to investigate and attribute deliberate biological events. Currently, no body can determine whether a pathogen outbreak was natural or engineered, creating plausible deniability for state-sponsored attacks.
Invest in genomic surveillance and early warning networks that can detect novel or engineered pathogens within days, not weeks. Current systems are designed for known pathogens and miss engineered variants.
Every nation must establish a national-level biosecurity authority responsible for dual-use research oversight, laboratory biosafety, and coordination with international partners. Most nations currently lack this capability.
Invest in platform technologies for rapid vaccine and therapeutic development. The exercise showed that traditional vaccine timelines (12–18 months) are too slow for engineered pathogens designed to evade existing countermeasures.
Like Event 201 and COVID-19, NTI Bio's scenario anticipated a real-world outbreak with remarkable specificity.
| Dimension | NTI Bio Scenario (2021) | Real-World Mpox (2022) |
|---|---|---|
| Pathogen | Engineered monkeypox (more transmissible) | Monkeypox (clade IIb, novel transmission pattern) |
| Scenario start date | May 15, 2022 | May 7, 2022 (UK case) |
| Origin | Fictional nation "Brinia" | Multiple countries simultaneously |
| Nature | Deliberate bioterror attack | Natural zoonotic (no evidence of engineering) |
| Vaccine response | Existing smallpox vaccines partially effective | Jynneos (smallpox vaccine) used for mpox |
| WHO response | PHEIC declared | PHEIC declared July 23, 2022 |
| Outcome | 271M dead (engineered worst case) | ~100 deaths globally (natural clade IIb) |
NTI explicitly stated that the real 2022 mpox outbreak showed no evidence of being engineered. The exercise was designed to explore a worst-case deliberate scenario — not to predict the natural outbreak. However, the timing coincidence and the similar pathogen made it the third exercise in the PSEF-X archive to eerily anticipate a real-world outbreak (after Event 201/COVID and SPARS/COVID).
| Exercise | Year | Predicted | Reality | Gap |
|---|---|---|---|---|
| Dark Winter | 2001 | Smallpox bioattack | Anthrax letters (2001) | 3 months |
| Event 201 | Oct 2019 | Novel coronavirus pandemic | COVID-19 (Dec 2019) | 2.5 months |
| NTI Bio | 2021 | Monkeypox outbreak (May 2022) | Mpox outbreak (May 2022) | 6 months |
