Solid organ xenotransplantation may have the potential to help address the shortage of organs for transplantation. There is concern, however, that a novel zoonotic disease could be transmitted from the source organ to the human recipient, and then from the recipient to others. Theoretically, this could result in an epidemic or pandemic. Because of this potential risk, it has been argued that collective consent is required. Our goal is to critically evaluate the claim that collective consent is necessary for xenotransplantation (...) to be ethically permissible. We argue that collective consent is not required and highlight the important roles of public engagement and due diligence in xenotransplant research moving forward. (shrink)
