The mother of a child whose life has been saved thanks to the stem cells from the birth of his brother, who was genetically modified to serve such a purpose, has said ‘Andrés is happy.’ The 7 year old boy has now overcome a severe hereditary congenital anaemia, thanks to the blood from Javier Mariscal, his newly born brother.
The couple explained that they had decided not to have another child with the problem, but when the possibility of the Pre-Implantation Genetic Diagnosis arose, they had no doubts, especially as they really wanted another child. Now Andrés will [presumably] have a normal life, instead of living just 35 years, the average for someone with what is now his previous condition.
Wishing the family well, and not wanting to be a Luddite, but readers can probably recite the ethical concerns for themselves.
