Social and Cultural Lives of Immune Systems introduces a provocative new hypothesis in medico-social theory - the theory that immunity and disease are in part socially constituted. It argues that immune systems function not just as biological entities but also as symbolic concepts charged with political significance. Bridging elements of psychology, sociology, body theory, immunology and medical anthropology, twelve papers from leading scholars explain some of the health-hazards of emotional and social pressure, whilst analysing the semiotic and social responses to the imagery of immunity.
