The Vatican announced Tuesday that the Catholic Church supports the use of animal organ transplants for treating human medical conditions, as scientists continue making progress with genetically modified organs from pigs and cattle.
Church officials released an extensive 88-page set of ethical guidelines that confirms Catholics face no religious barriers to receiving these life-saving procedures, as long as medical professionals follow established standards and avoid cruelty to animals.
“Catholic theology does not have preclusions, on a religious or ritual basis, in using any animal as a source of organs, tissues or cells for transplantation to human beings,” the document said.
The guidelines focus on xenotransplantation – the medical practice of moving organs or tissue between different species. While the Vatican initially approved these procedures back in 2001 when the technology was just beginning to develop, such transplants remain uncommon today.
Medical breakthroughs in this field are still emerging, with the first successful pig kidney transplant into a human patient taking place in the United States just this year.
Medical experts from Italy, the United States, and the Netherlands collaborated with Vatican officials to create the document, which urges researchers to approach animal transplantation in ways that are “purposeful, proportionate and sustainable.”
The guidelines also emphasize that physicians must fully inform patients about potential complications, including the chance their immune system could reject the transplanted organ and the risk of infections from animal-based microorganisms.
