Human Fertilisation and Embryology Bill [Lords]

That is a helpful intervention, because the distinction must be borne in mind. With saviour siblings, we are dealing not just with a fortuitous match, but a child who has been deliberately created and tissue typed for the purpose of matching the sick sibling. That is the deliberate reason for their creation. When one comes before the Human Tissue Authority, one cannot be wholly sure about the dangers that I have set out—that the child will be a lifelong donor—because it has not been possible to provide the cord blood or bone marrow match as a resource, but the sick sibling in that family still needs the cure for their debilitating illness, but has an immune, matched sibling, who has a genetic footprint that potentially provides the answer.
