Multiple attacks on health have been reported in the Iranian capital, Tehran, in recent days amid the escalating conflict in the Middle East. The Pasteur Institute in Iran sustained significant damage and was rendered unable to continue delivering health services. The Institute was established in 1920 and has been operating for over a century in multiple areas of medical research. It plays an important role in protecting and promoting population health, including in emergencies. Two of its departments have been working with WHO as collaborating centres. …The conflict in Iran, and the region, is impacting the delivery of health services and the safety of health workers, patients, and civilians present at health facilities. Peace is the best medicine
