The Vatican recently announced that it has no ethical objections to the transplantation of animal organs into humans – a process known as xenotransplantation. (See Vatican approves use of animal transplants ‘to benefit humans’)

In a letter to Nature, Archbishop Monsignor Elio Sgreccia et al endorse the Vatican’s conclusions and argue that the vast healthcare resources that would be used for xenotransplantation are justified by the urgent need to save patients’ lives.

They also call for more information on the potential benefits and risks of xenotransplantation and encourage public debate on these issues.
