Minority populations are often regarded as being ‘hard to reach’ and evading state expectations of health protection. This ethnographic and archival study analyses how devout Jews in Britain negotiate healthcare services to preserve the reproduction of culture and continuity. This book demonstrates how the transformative and transgressive possibilities of technology reveal multiple pursuits of protection between this religious minority and the state. Making Bodies Kosher advances theoretical perspectives of immunity, and sits at the intersection of medical anthropology, social history and the study of religions.
