The Pasteur Institute of Iran has sustained extensive damage during recent hostile aerial bombardments over downtown Tehran. The downtown campus sustained damage during three raids, most recently on 23 March 2026. Despite the destruction, reference laboratories continue to operate, and the clearance of debris and reconstruction of damaged sections have begun. During these attacks, approximately 1,600 square meters of buildings have been destroyed or severely damaged. Lost units include the departments of Malaria, Cell Bank, Clinical Research, and Biotechnology, as well as buildings related to Information Technology, Engineering, Physical Protection, and the National Research Network secretariats — rendering these buildings unusable. Moreover, laboratory equipment, consumables, and biological samples have been destroyed. Based on early estimates, tens of millions of euros are needed to reconstruct the destroyed structures, repair 20,000 square meters of damaged areas, replace research and diagnostic equipment, and restore cellular, plasmid, bacterial, and viral stocks. Authorities note that procuring specialized equipment remains a serious challenge under the country’s sanctions regime.
