The Vetter family was happy when their child was born. Unfortunately, the happiness did not last long. Soon the heir died, and the doctors explained this by the fact that the boy had no immunity at all. Doctors warned the spouses that the situation could repeat itself next time. However, the Vetters dreamed of an heir and deliberately took risks. The couple had a son, David, who was immediately placed in a sterile box.
The Vetters' daughter was to become a donor for the baby: the doctors were sure that the girl's bone marrow transplant would save David's life. Subsequently, it turned out that the Vetters' daughter could not become a donor for her brother. The doctors decided to leave the boy in a bladder. It turns out that the doctors initially used David for their experiment, which was funded by the state.
David did not go outside, the child could only be touched with gloves. Sometimes the parents took the baby: into the home bubble. However, the boy's existence could hardly be called a carefree childhood. Once, David found a syringe in his monastery, which the nurse had forgotten and began to pierce the walls of the bladder.
The doctors had to tell the boy the whole truth. This conversation influenced the child's state of mind. Soon, NASA built a special spacesuit in which David could go out. The boy resisted at first, however, soon curiosity got the better of the child.
David managed to make his little "trips" into the big world only 7 times. Soon David grew out of the spacesuit. The doctors nevertheless decided to take a crucial step, persuading the boy's parents to undergo a bone marrow transplant operation. The doctors hoped for a miracle. After the boy was removed from the bladder, the condition worsened.
David passed away 12 days later. A virus was found in the bone marrow of donor David, which was not detected by the doctors in time. David passed away when he was 12.
