Splenectomies, immune system development, and schizophrenia

Chris is incapacitated in bed today with the flu and running a fever. I can’t recall when he was ever sick as a child or adult. Not a cold, not a fever, no ear aches, stomach aches, nothing. For the past month he’s been taking drops that are supposed to strengthen his zero functioning immune system, according to the naturopath. There is now something quite bizarre going on. Occasional flus and fevers are normal. Perfect physical health like Chris has experienced is not. If Chris’s immune system begins to function  (“if“)  will this mean that he will trade his particular brand of “schizophrenia” for different health concerns or more everyday health? The immune link interests me because my spleen was removed as a child due to thrombocytopenic purpura, which suggests that Chris may have an inherited autoimmune condition.
