The Pasteur Institute in Tehran Was Just Bombed — Why This Is the Most Concerning Strike of the War

The US-Israeli strikes hit the Pasteur Institute of Iran — a 100-year-old medical research centre. Here is why this specific strike has drawn the most international condemnation.

The strike on the Pasteur Institute of Iran — a medical research institution founded in 1920 with French technical assistance and whose history of vaccine development, infectious disease research, and public health contribution spans a century — produced the most uniform international condemnation of any single strike in the 35-day campaign, and understanding why requires understanding what the Pasteur Institute actually is and does.

The institute's specific work: vaccine production (hepatitis B, rabies, polio), antivenom manufacturing (for the snake and scorpion bites that are significant public health threats in Iran's geography), infectious disease diagnostic services (the institute has been the primary Iranian institution for COVID-19 and related pathogen research), and antibiotic production for the Iranian domestic market. It is the specific institution that produces the medical countermeasures whose absence most directly harms civilian health outcomes.

US justification for the strike: unnamed US officials provided Al Jazeera's Washington correspondent with the characterisation that the institute had 'dual use' research capabilities — the specific phrase that covers any laboratory facility whose equipment could theoretically be used for biological research with both civilian and military applications. Centrifuges, fermenters, and incubators that produce vaccines could theoretically produce other things.

For the international response: the specific combination of the institute's century-old history, its exclusively civilian-facing output in normal operation, and the specific vaccine production it provides to a civilian population under bombardment makes the 'dual use' justification its least credible application in the campaign. The Pasteur Institute response received specific condemnation from the World Health Organisation, MSF, and the International Committee of the Red Cross — organisations whose specific mandate gives their condemnation unusual weight.

For the medical humanitarian dimension: the strike on the Pasteur Institute, alongside the drone attack on a Red Crescent aid warehouse in Bushehr Province and the cumulative damage to Iranian healthcare infrastructure, represents the specific intersection of military targeting and civilian healthcare that international humanitarian law was designed to prevent.
