Radiolab revisits its 2009 hookworm episode, exploring how these parasites may treat autoimmune diseases and type 2 diabetes by regulating the immune system. Hosts Latif Nasser and Molly Webster feature the story of Jasper Lawrence, who self-treated his allergies with hookworms, and discuss new clinical trials led by Dr. Paul Jagerman.
