Davi Phillip Vetter (September 21, 1971 – February 22, 1984) was a boy from Shenandoah, Texas, United States who suffered from a rare genetic disease now known as severe combined immune deficiency syndrome (SCIDS). Forced to live in a sterile environment, he became popular with the media as the boy in the plastic bubble. He spent most of his life at Texas Children's Hospital, but in 1981, David was discharged to his parents' full-time care. He died of cancer shortly after a hematopoietic stem cell transplantation.
