Bubble boy

David Phillip Vetter (September 21, 1971 – February 22, 1984) was an American who was a prominent sufferer of severe combined immunodeficiency (SCID), a hereditary disease which dramatically weakens the immune system. Individuals born with SCID are abnormally susceptible to infections, and exposure to typically innocuous pathogens can be fatal. Vetter was referred to as “David, the bubble boy” by the media, as a reference to the complex containment system used as part of the management of his SCID.

Water, air, food, diapers and clothes were sterilized before entering the sterile chamber. Items were placed in a chamber filled with ethylene oxide gas for four hours at 60˚C, and then aerated for a period of one to seven days before being placed in the sterile chamber.

When Vetter was four years old, he discovered that he could poke holes in his bubble using a butterfly syringe that was left inside the chamber by mistake. At this point, the treatment team explained to him what germs were and how they affected his condition. As he grew older, he became aware of the world outside his chamber, and expressed an interest in participating in what he could see outside the windows of the hospital and via television.

In 1977, researchers from NASA used their experience with the fabrication of space suits to develop a special suit that would allow Vetter to get out of his bubble and walk in the outside world. The suit was connected to his bubble via a 2.5 m long cloth tube and although cumbersome, it allowed him to venture outside without serious risk of contamination. Vetter was initially resistant to the suit, and although he later became more comfortable wearing it, he used it only seven times. He outgrew the suit and never used the replacement one provided for him by NASA.

In his first years of life he lived mostly at Texas Children’s Hospital in Houston, Texas. As he grew older, he lived increasingly at home with his parents and older sister Katherine in Dobbin, Texas. He died in 1984, at the age of 12 from complications of a bone marrow transplant provided by his sister. His mother touched his skin for the first time only several hours before his death.
