Guns of peace and an early campaign against smallpox

This article analyses the religious and other motivations of Robert Hingson and Brother's Brother Foundation in their work on smallpox eradication and international health more broadly. It examines Hingson's development and early usage of the jet injector in mass vaccination campaigns. It also highlights that in offering logistical support to Hingson's efforts in Liberia, the US government participated in smallpox eradication earlier than existing narratives have suggested.
