What Is Severe Combined Immunofeficiency
(SCID)?
Severe Combined Immunodeficiency (SCID) may be best known
from news stories and a movie in the 1980s about David, the Boy
in the Bubble, who was born without a working immune
system.
Caused by defects in any of several possible genes, Severe
Combined Immunodeficiency makes those affected highly
susceptible to life-threatening infections by viruses, bacteria
and fungi.
Because David's brother had died of the disease, doctors
immediately placed him into a plastic isolation unit to protect
him from infections. He lived in such isolators for nearly 13
years.
David died in 1984 following an unsuccessful bone marrow
transplant, an attempt to provide him with the capacity to
fight infections on his own and thus free him from the
bubble.
