severe+combined+immunodeficiency+(SCID)

David Vetter was born with severe combined immunodeficiency (SCID), meaning his body had no immune system to fight off diseases of any sort. Because his older brother had died from complications of the same disease, his parents were prepared for David's birth and arranged for a germ-free delivery on September 21, 1971, at Texas Children's Hospital in Houston. Once it was determined that David was also afflicted with SCID, he stayed in plastic isolator bubble environments while waiting for a matching bone marrow donor or a cure for his ailment. The long wait would last twelve years. (from the PBS site)

David Vetter (September 21, 1971 -- February 22, 1984) became famous for living in a sterile environment. He was born with severe combined immunodeficiency (SCID), a disorder that causes the immune system to not work. Because of this, exposure to any germs could prove fatal. He was called "David, the bubble boy" by the news media. Although they knew his last name, they didn't use it in order to give David and his family privacy. His last name was not revealed to the general public until 10 years after his death.  As Sage told us, the video is in parts. Here is the link to part 1, etc, although you can find the 2nd & 3rd clips in the related videos:

I do *not* endorse, nor recommend any of the other "related videos" in the side bar. Unless it is about Abby and Brittany Hensel, who are conjoined twins and have a rather interesting story. But, seriously, I would not google around cuz people put up disturbing, unscientific stuff.
