A Gene to Cure Blindness
May 22, 2007
It took 15 years to get the right gene, to neutralize a virus that could carry it, and to prove — first in test tubes and then in live animals — that the procedure was safe enough for humans. Finally a young man named Robert Johnson got the first shot. A team of U.K. doctors announced earlier this month, that they put a needle through Johnson’s eye, into his retina, to replace the faulty gene that had been blinding him for years. (TIME)
