Bubble Boy Disease, also known as Severe Combined Immunodeficiency (SCID), is a rare genetic disorder that severely weakens the immune system. Individuals with this condition are unable to fight off infections, making them highly vulnerable to even minor illnesses. The name "Bubble Boy" comes from the famous case of David Vetter, a boy who lived in a sterile environment to protect him from germs. Treatment options for SCID include bone marrow transplants and gene therapy, which aim to restore the immune system's function and improve the quality of life for affected individuals.
