NARRATION: Last December, every newborn in the nation began to be screened for a rare genetic disease called severe combined immunodeficiency, or SCID. It was a groundbreaking moment.

HEATHER SMITH (ADVOCATE FOR SCID FAMILIES): Babies that are picked up at birth with SCID have a 94 percent chance of successfully going on and leading a normal life.

NARRATION: But the achievement might never have been possible were it not for the story of one little boy.

CAROL ANN DEMARET (DAVID VETTERS MOTHER): David was born September 21, 1971. I heard the first sounds of life, and he was placed in an isolator, in a bubble that was a few feet from me. We thought that the immune system was just slow to develop. There was never any plan to keep David in there in the bubble indefinitely.

NARRATION: The sterile bubble was the brainchild of doctors who feared the worst severe combined immuneodeficiency a rare genetic defect that had taken the life of Davids brother the year before. But it fell short of a cure.

CAROL ANN DEMARET: It was a gradual realization that his immune system was not going to spontaneously function. So I trusted science would find an answer for us next year, then the next year.

ARCHIVAL (NBC, 2-25-75):HARRY REASONER: This three-year-old boy you see in that picture has spent his entire life in a plastic bubble.

ARCHIVAL (CBS, 6-25-73):ED RABEL: To expose him to the air would be to kill him.

ARCHIVAL (NBC, 2-25-75):GEORGE LEWIS: His food, clothes and toys have to be sterilized and placed inside the bubble with sterile, rubber gloves.

NARRATION: As the years passed with no solution

ARCHIVAL (CBS, 11-3-77):ERIC ENGBERG: Since his birth six years ago, David has lived in a plastic world.

NARRATION: America tuned in to watch the milestones of his curious life unfold.

ARCHIVAL (CBS, 11-3-77):ROGER MUDD: The scientists who sent men to the moon have achieved another first. They have found a way to open up the world of a small, Houston boy who has spent his life inside a sterile bubble.

ARCHIVAL (ABC, 11-3-77):SNELL: That he was excited by his newfound freedom is obvious from the NASA film. David wanted to do everything.

ARCHIVAL (CBS, 11-3-77):I think the best portrayal of his reaction is when he held up his hands, the fascination of seeing his hands in the small gloves for the first time.

ARCHIVAL (ABC, 11-3-77):SNELL: Now it is possible for him to play catch with his sister and dream of even more.

NARRATION: The nightly news was just the start. Soon, his story took on a life of its own.

ARCHIVAL (BOY IN THE BUBBLE TRAILER, 1976):ANNOUNCER: John Travolta is the boy in the plastic bubble.

CAROL ANN DEMARET: David was unique, and people pay attention things that are unique. When he was about nine years old, he looked at me, and he said, Well, Im a star. I dont have to clean my bubble. And I thought he meant like a star in heaven. And I said, Oh, yes, you are; because you light up my life. And he said, Well, not that kinda star. Im famous.

NARRATION: But Davids predicament brought him more than fame.

CAROL ANN DEMARET: Certain things would filter back about the ethics involved in keeping a boy in this germ-free environment.

ARCHIVAL (CBS, 6-25-73):ED RABEL: What about the day he says, I want out of here, and you cant let him out?

ARCHIVAL (University of Virginia, Medicine and Society Conference, 1975):Im not sure that the quality of life which has been created for David is going to very long be a very desirable one for him.

CAROL ANN DEMARET: To keep a child isolated, unable to touch, or feel, or smell, or enjoy, sounds cruel, perhaps. What did they expect us to do take David out of the bubble, which would have been certain death?

ARCHIVAL (BAYLOR COLLEGE OF MEDICINE):TEACHER (SPEAKING TO DAVID): Tell me the letters.DAVID VETTER: I, P, O, P. I try to do my best in school.TEACHER: I know you do.

DR. WILLIAM T. SHEARER, 1937-2018 (DAVID VETTERS IMMUNOLOGIST): We all knew that a day would come when a decision would have to be made, either in or out. Everybody knew that this isolator system just couldnt continue forever.

NARRATION: David had grown into an adolescent without a clear road forward. But medical advances were cause for hope.

CAROL ANN DEMARET: They were having success with bone marrow transplant from an unmatched donor. Everything seemed to come into play. He would be free, or we would go back to square one.

ARCHIVAL (ABC, 10-21-83):DR. RALPH FEIGIN: At 3 a.m. David did receive a bone marrow transplant administered by Dr. Shearer.

ARCHIVAL (NBC, 10-21-83):TOM BROKAW: The new bone marrow, which comes from his sister, could spur his body into developing an immune system.

DR. WILLIAM T. SHEARER: Everything was just fine. His blood pressure stayed good.

CAROL ANN DEMARET: There was nothing different, except New Years Eve. There was an elevation in temperature. And the next day, it elevated again.

ARCHIVAL (ABC, 2-8-84):PETER JENNINGS: Today David has been removed from his bubble for the first time in his life, but the reason for his freedom is not good news.

ARCHIVAL (NBC, 2-21-84):TOM BROKAW: David, the 12-year-old boy who lived in a plastic bubble until two weeks ago, is listed in critical condition tonight.

CAROL ANN DEMARET: Unforeseen things happened, and thats what we live with.

ARCHIVAL (CBS, 2-23-84):DR. WILLIAM T. SHEARER: David was always joking. He said something to the effect that, Here we have all of these tubes and all of these tests, and nothings working, and Im getting tired. He said, Why dont we just pull all of these tubes out and let me go home?

ARCHIVAL (ABC, 2-23-84):PETER JENNINGS: Twelve years ago in this country a very unusual baby was born. He died last night, two weeks after emerging into a world his body could not tolerate.

NARRATION: Carol Ann vowed that Davids life would not be in vain.

DR. R. MICHAEL BLAESE (IMMUNE DEFICIENCY FOUNDATION): Davids story was repeated before the Congress as a way of putting a face and a name to the problem and helping people understand why its important to fund research.

NARRATION: Dr. Michael Blaese, a gene therapy pioneer, has been studying immune deficiency diseases for more than five decades. He says that in the years that followed Davids death, progress in bone marrow transplantation alone offered most children a virtual cure.

DR. R. MICHAEL BLAESE: We know that if transplantation is done sometime in the first three months, that the chances of cure is in the range of 95 percent.

NARRATION: But quick diagnosis was key.

ARCHIVAL (HEATHER SMITH HOME MOVIES):Theres Brandon. Brandon Michael. Hes one hour old. Hes exactly one hour old.

HEATHER SMITH: Brandon looked like a healthy, normal baby at birth.

ARCHIVAL (HEATHER SMITH HOME MOVIES, 1993):Brandons got his pacifier. And hes trying to put it back in his mouth. He was 8 weeks old yesterday. And hes almost 3 months old. (Sneezes) Oh, Bless you. Hes just sneezing.


HEATHER SMITH (BRANDON DAHLEYSMOTHER): Until he became about six months of age and came down with what we thought was his first cold.

ARCHIVAL (HEATHER SMITH HOME MOVIES, 1993):Yesterday Heather had to take Brandon into the doctor because he didnt feel good.

HEATHER SMITH: We had no family history of any kind of serious conditions, so, really, we were hoping that whatever it was that Brandon had, he was going to be able to fight and get over. Unfortunately, instead of getting better, he got progressively worse.

NARRATION: Within days, she was rushing Brandon to the hospital.

HEATHER SMITH: His fingernails were blue. His lips were blue it was quite obvious that he was struggling to breathe.

NARRATION: But, for three weeks, doctors couldnt figure out what was wrong with the child.

HEATHER SMITH: It was after the skin biopsy came back that they first told us they thought he had SCID. They explained to me a little bit more, We dont put babies in bubbles anymore, but what we do for them to treat this is a bone marrow transplant. However, they said at that point that Brandon was just way too sick. Weve done everything that we can for him and, unfortunately, were going to have to turn the machines off. All the family came in and too their turns saying goodbye.

DR. R. MICHAEL BLAESE: If you can identify the patient and get them treated you essentially cure them almost all of them. But once they have that infection that first infection success rate drops substantially. Its a problem of rare disease. Patients get missed.

NARRATION: Most pediatricians still couldnt recognize the signs of SCID. Awareness of the disease had receded along with David Vetters story replaced in the publics mind by an image that had only the vaguest connection to the boy who had once captivated the nation.

ARCHIVAL (CLIP FROM SEINFELD):What are you looking at? Never seen a kid in a bubble before?GEORGE CASTANZA: Course I have, come on My cousins in a bubble.

ARCHIVAL (THE SIMPSONS):You will be living in this bubble. It is clear plastic so the world can see how normal you are.. Ha Ha. Ha.

NARRATION: Such portrayals were painful to the parents of immune deficient children. But they had one unexpected upside publicity.

HEATHER SMITH: That was very hurtful. But our driving focus is newborn screening to let the world know that this is a condition thats still taking our babies lives every day.

NARRATION: The death of Heather Smiths first child had taught had her that early detection was essential. Forewarned, her second baby was given a landmark bone marrow transplant while still in the womb.

Taylor is now 24 years old and has just graduated from college.

HEATHER SMITH: And to look at him, youd have no idea that he has a condition called severe combined immune deficiency.

NARRATION: Today, gene therapy is at the forefront of treating the disease.

ARCHIVAL (NBC):NEWS REPORT: Doctors take out the patients bone marrow and replace their defective gene with a healthy copy, then re-infuse the cells back into the patient.

NARRATION: In 2008, advocates like Heather Smith helped push Wisconsin to begin screening all newborns for severe combined immune deficiency. In fits and starts, other states followed suit. Leading to the realization that this genetic defect was more common than generally thought.

HEATHER SMITH: Davids story is still helping people today, 30 years later.

NARRATION: And not just as a symbol. Important medical advances resulted from studying the young boy. From the discovery of the damaged gene that causes the most common form of SCID to another revelation.

ARCHIVAL (CBS, 5-1-85):DAN RATHER: The little Houston boy provided a vital missing link between a common viral infection and the development of cancer.

NARRATION: The final tragedy of Davids life was that the transplant had initially worked. But, unbeknownst to doctors, the donors bone marrow contained remnants of an old virus, which, when transferred into Davids immune-compromised body, triggered an aggressive cancer.

It was the first time this connection had been observed.

DR. WILLIAM T. SHEARER: What he gave us was a powerful lesson in many areas of medicine and just in in life itself. David was a very courageous boy.

CAROL ANN DEMARET: I always thought at some point when David left the bubble that he would be a researcher himself and would help mankind that way.


CAROL ANN DEMARET: It turned out that he is helping mankind, but in a different way.
