Question: What is the birthdate of this prominent sufferer of severe combined immunodeficiency, referred to as the bubble boy, famous for living in a sterile environment?

full_context: Document 1: Severe combined immunodeficiency (non-human): The severe combined immunodeficiency (SCID) is a severe immunodeficiency genetic disorder that is characterized by the complete inability of the adaptive immune system to mount, coordinate, and sustain an appropriate immune response, usually due to absent or atypical T and B lymphocytes. In humans, SCID is colloquially known as "bubble boy" disease, as victims may require complete clinical isolation to prevent lethal infection from environmental microbes.
Document 2: Strimvelis: Strimvelis is the first "ex-vivo" stem cell gene therapy to treat patients with a very rare disease called ADA-SCID (Severe Combined Immunodeficiency due to Adenosine Deaminase deficiency), a rare disorder caused by the absence of an essential protein called adenosine deaminase (ADA), which is required for the production of lymphocytes. Children born with ADA-SCID do not develop a healthy immune system so cannot fight off everyday infections, which results in severe and life-threatening illness. Without prompt treatment, the disorder often proves fatal within the child’s first year of life. ADA-SCID is estimated to occur in approximately 15 patients per year in Europe.
Document 3: Colt clan incest case: The Colt family incest case, dubbed by media as the Colt incest clan, is an Australian family discovered in 2012 to have been engaging in four generations of incest beginning with "Tim and June Colt," a brother and sister who emigrated from New Zealand in the 1970s. The family grew to nearly 40 members ranging from grandparents to mothers, fathers, sons, daughters, aunts, uncles, nephews, brothers and sisters all engaging in various forms of incest. Many of the children suffered from deformities and medical problems. The case has been described by lead investigator Peter Yeomans as, "like nothing I’ve ever seen," and was considered by many to be so shocking that in a rare move the Australian family court allowed full details to be made public, albeit with all names changed to pseudonyms for the children's protection, including the family name of "Colt."
Document 4: David Vetter: David Phillip Vetter (September 21, 1971 – February 22, 1984) 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. Vetter's surname (last name) was not revealed to the general public until 10 years after his death in order to preserve his family's privacy.
Document 5: Ray Stehr: Stehr was born in the country New South Wales town of Warialda in 1913. As an eight-year-old child, he was diagnosed an "incurable cripple" after developing blood clots at the base of his spine. He was unable to walk for two years and spent twelve months strapped to a stretcher, completely immobilised with his back encased in a plaster cast. His family moved to Sydney in search of some kind of miracle cure and, following a visit to a Chinese herbalist, the clots began to disappear. Nevertheless, Stehr was told not to contemplate playing contact sport. Stehr defied medical opinion, becoming one of rugby league's toughest front rowers.
Document 6: Sunday O. Fadulu: Dr. Sunday O. Fadulu is a noted microbiologist and medical researcher most recognized for his work with sickle cell anemia. He holds a patent for the treatment of the disease which claimed the lives of two of his brothers in Nigeria. Fadulu enrolled at Oklahoma Baptist University in 1961, with the encouragement of a Southern Baptist missionary he met. Speaking of his father and the death of his brothers, he has stated, "My father was a man who would never fail. He was so strong," Fadulu said in the chapel service. "The night my brother died, he had my brother in his arms, and I saw his face, and it said that he had failed. I remember the discouragement on his face. I said then that I would find a cure and to do that I would have to go to America." Fadulu's research used an extract of the African "chewing stick," which he discovered, reverses sickling of red blood cells. The extract also provides protection from the disease. Medication for treating sickle cell anemia has been through the first phases of approval through the Federal Food and Drug Administration.
Document 7: Immunodeficiency: Immunodeficiency (or immune deficiency) is a state in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. Most cases of immunodeficiency are acquired ("secondary") due to extrinsic factors that affect the patient's immune system. Examples of these extrinsic factors include HIV infection, extremes of age, and environmental factors, such as nutrition. In the clinical setting, the immunosuppression by some drugs, such as steroids, can be either an adverse effect or the intended purpose of the treatment. Examples of such use is in organ transplant surgery as an anti-rejection measure and in patients suffering from an overactive immune system, as in autoimmune diseases. Some people are born with intrinsic defects in their immune system, or primary immunodeficiency. A person who has an immunodeficiency of any kind is said to be immunocompromised. An immunocompromised person may be particularly vulnerable to opportunistic infections, in addition to normal infections that could affect everyone. Immunodeficiency also decreases cancer immunosurveillance, in which the immune system scans the body's cells and kills neoplastic ones.
Document 8: The Boy in the Plastic Bubble: The Boy in the Plastic Bubble is a 1976 American made-for-television drama film inspired by the lives of David Vetter and Ted DeVita, who lacked effective immune systems. It stars John Travolta, Glynnis O'Connor, Diana Hyland, Robert Reed, and P.J. Soles. It was written by Douglas Day Stewart, executive produced by Aaron Spelling and Leonard Goldberg (who, at the time, produced "Starsky and Hutch" and "Charlie's Angels"), and directed by Randal Kleiser, who would work with Travolta again in "Grease" shortly after. The original music score was composed by Mark Snow. The theme song "What Would They Say" was written and sung by Paul Williams. William Howard Taft High School in Woodland Hills was used for filming.
Document 9: Severe combined immunodeficiency: Severe combined immunodeficiency, SCID, also known as alymphocytosis, Glanzmann–Riniker syndrome, severe mixed immunodeficiency syndrome, and thymic alymphoplasia, is a rare genetic disorder characterized by the disturbed development of functional T cells and B cells caused by numerous genetic mutations that result in heterogeneous clinical presentations. SCID involves defective antibody response due to either direct involvement with B lymphocytes or through improper B lymphocyte activation due to non-functional T-helper cells. Consequently, both "arms" (B cells and T cells) of the adaptive immune system are impaired due to a defect in one of several possible genes. SCID is the most severe form of primary immunodeficiencies, and there are now at least nine different known genes in which mutations lead to a form of SCID. It is also known as the bubble boy disease and bubble baby disease because its victims are extremely vulnerable to infectious diseases and some of them, such as David Vetter, have become famous for living in a sterile environment. SCID is the result of an immune system so highly compromised that it is considered almost absent.
Document 10: Sickle-cell disease: Sickle-cell disease (SCD) is a group of blood disorders typically inherited from a person's parents. The most common type is known as sickle-cell anaemia (SCA). It results in an abnormality in the oxygen-carrying protein haemoglobin (hemoglobin S) found in red blood cells. This leads to a rigid, sickle-like shape under certain circumstances. Problems in sickle cell disease typically begin around 5 to 6 months of age. A number of health problems may develop, such as attacks of pain ("sickle-cell crisis"), anemia, swelling in the hands and feet, bacterial infections, and stroke. Long term pain may develop as people get older. The average life expectancy in the developed world is 40 to 60 years.
Document 11: Everything, Everything (novel): Everything, Everything is the debut young adult novel by American author Nicola Yoon, first published by Delacorte Books for Young Readers in 2015. The novel centers around 18-year-old Madeline Whittier, who has severe combined immunodeficiency (SCID), also known as "bubble baby disease". Due to her condition, Madeline is stuck inside her house in Los Angeles, where she lives with her mother and a physician who takes care of her.
Document 12: Newborn Screening Saves Lives Act of 2007: President George W. Bush signed the Newborn Screening Saves Lives Act of 2007 (Pub.L.110-204) (NBSSLA) into law on April 24, 2008, a day before DNA Day. The Act amended the Public Health Service Act to establish grant programs concerning newborn screening education and outreach, as parents are often unaware that newborn screening takes place and the number and types of screening varies across states. It also established grant programs to coordinate follow-up care, after newborn screening is conducted. The legislation also reauthorized programs under part A of title XI of the Public Health Service Act. In his introductory remarks, Senator Chris Dodd stated that the legislation “protect[s] the most vulnerable members of our society: newborn infants.” Newborn Screening is a proven life saving and effective public health tool used to identify thousands of babies in the U.S. born with genetic, metabolic, and congenital conditions. At the time of the legislation’s passage, only 15 States along with the District of Columbia required newborns to be screened for 29 core conditions as recommended by the Health Resources and Services Administration/American College of Medical Genetics’ 2004 Report.
Document 13: X-linked severe combined immunodeficiency: X-linked severe combined immunodeficiency (X-SCID) is an immunodeficiency disorder in which the body produces very few T cells and NK cells. In the absence of T cell help, B cells become defective. It is an x-linked recessive trait, stemming from a mutated (abnormal) version of the IL2-RG gene located at xq13.1 on the X-chromosome, which is shared between receptors for IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21.
Document 14: Severe combined immunodeficient mice: Mice with severe combined immunodeficiency (SCIDs) are often used in the research of human disease. Human immune cells are used to develop human lymphoid organs within these immunodeficient mice, and many different types of SCID mouse models have been developed. These mice allow researchers to study the human immune system and human disease in a small animal model.
Document 15: William French Anderson: William French Anderson (born December 31, 1936) is an American physician, geneticist and molecular biologist. He is considered a pioneer of gene therapy. He graduated from Harvard College in 1958 and from Harvard Medical School in 1963. In 1990, he claimed to be the first person ever to succeed in gene therapy of a 4-year-old girl suffering from severe combined immunodeficiency (a disorder called "bubble boy disease"). His claims may have been exaggerated, albeit, he was not alone. In 2006, he was convicted of sexual abuse of a minor and in 2007 was sentenced to 14 years in prison.
