Bubbles seem to be fragile to a poke and break, but seemingly fragile bubbles have become a shelter for some people, in the 70s of the last century, a boy in the United States lived in a "bubble", he died at the age of 12, but also at the age of 12 for the first time contact with his mother.
The boy, David Philippe Vettel, was born in 1971 to very healthy parents, but unfortunately both have SCID, a congenital genetic disorder with very severe combined immunodeficiency.
It is characterized by the presence of the X chromosome, boys have a 50% chance of getting sick, girls also have a chance of becoming carriers, Vettel parents have a total of three children, two boys and a girl, the girl Catherine is not sick, she is healthy, but Vettel's brother died seven months after birth.
When they were pregnant with Vettel, they also had concerns, but they were Catholics, they could not beat the fetus, they gave birth to Vettel with a glimmer of hope, but unfortunately their hopes were dashed, Vettel also suffered from immunodeficiency, this disease is actually very rare, newborns only have a one in 100,000 chance of getting sick.
But because Vettel's parents carry disease-causing genes, the chance of disease in this family is as high as one-half, the diseased Vettel can not touch ordinary air, immune deficiencies make lymphoid T cells lose their basic bactericidal immunity, even a little germ is enough to kill.
Vettel was sent to a sterile environment in the membrane from the moment of birth, and his parents couldn't even hug him, but the doctor suggested that they see some light, they could use Catherine's hematopoietic stem cells for bone marrow transplantation, so that Vettel could differentiate normal immune cells.
But just after seeing the dawn, a basin of cold water was poured down, Catherine and Vettel's matching was not successful, he could only continue to live in the sterile bubble, the family could only visit him through the sterile membrane every day, in order to prevent him from bored, his parents prepared a lot of toys and gifts for Vettel.
These toys and gifts also need to be sterilized for a long time before they can be sent into the bubble, since Vettel's deeds were reported out, attracting national attention, some media also filmed him a documentary, when he was 6 years old, Vettel received a special birthday gift.
NASA made a special set of spacesuits for Vettel, and Vettel, who changed into a spacesuit, could go outside to play with his sister Catherine, but he only wore this outfit seven times before losing interest, because the spacesuit was too cumbersome, and there was a two-meter-long catheter behind the clothes to provide him with oxygen.
Vettel just went from one "cage" to another, as he grew older, he gradually realized that he was different, he stayed in the bubble and lost the innocence of childhood, his face was full of sorrow, just at the age of 12, he developed a bone marrow transplant technique that did not require matching.
Vettel also came out of the bubble and experienced the life of a normal person, but just 4 months after the transplant, Vettel developed lymphoma, and it turned out that in Catherine's blood, they also found a virus, Epstein-Barr virus, which re-destroyed the immune mechanism and took his life.
