This article proposes a theorization of immunity from an embodied autoimmune perspective. Arguing through what it identifies as the limitations in current clinical immunology explanations and politico-philosophical theories of immunity, the article seeks to embody, rather than metaphorize, the theoretical stakes of current immune theory. As a counterargument to dominant theorizations of immunity that pathologize or metaphorize the autoimmune bodily experience, the article forwards a more spacious, material, and affirmative theorization of the body. As the author supplements existing immune theory with their own emergent and embodied theory, they develop an autoimmune methodology based on their experience of living with an autoimmune disease. Part personal narrative, part speculative autoimmune theory, the article ultimately calls for a practice of self-care aimed at coming to tolerate the disagreeing community of the autoimmune body as it challenges normalized notions of what self and other, immunity and community, ease and disease mean.
