Question: What is the birthdate of this prominent sufferer of severe combined immunodeficiency, referred to as the bubble boy, famous for living in a sterile environment?
Sentence (from "Severe combined immunodeficiency"): SCID involves defective antibody response due to either direct involvement with B lymphocytes or through improper B lymphocyte activation due to non-functional T-helper cells. Consequently, both "arms" (B cells and T cells) of the adaptive immune system are impaired due to a defect in one of several possible genes.
Relevant evidence: No
