Quizplus · Accepted Answer

A bone marrow transplant would be the most effective treatment for a patient with SCID since it would replace the defective stem cells with healthy ones that would produce functional immune cells. Intravenous antibiotics and repeated doses of antisera may offer temporary relief from infections but would not improve the underlying immune deficiency. Multiple immunizations would also not be effective since the patient's immune system is unable to mount a response to antigens.
