Mazie Bond, a 12-year-old Salt Lake girl who underwent a lung transplant operation Oct. 25 at Stanford Medical Center in Palo Alto, Calif., is "doing wonderfully," according to a hospital spokeswoman.

"She's off all medication except anti-rejection drugs, and she's up and walking around the hospital," Terrie Gordon-Gamble, clinical nursing supervisor at the hospital, said earlier. The girl, who had been in the adult cardiovascular intensive care unit to protect her from childhood diseases in the pediatric unit, is out of intensive care and in stable condition, a nursing supervisor said early Monday.Gordon-Gamble said she won't be ready to go home for about three weeks or until doctors are sure that her body won't reject the transplanted lung..

The top third of her mother's right lung is now Mazie's new right lung. She is the first person to receive a lung from a live donor. Previously, lung transplants came from brain-dead donors only.
