Typically, the savior sibling provides bone marrow or stem cells from the umbilical cord blood, which is collected at birth and then transfused into the child who is ill and in need of a donor. The savior sibling may be needed once for the medical treatment of their sick sibling or on a repeated basis if needed.
The creation of the savior sibling takes place in the laboratory. Eggs are harvested from the mother. Sperm is collected from the father. Embryos are created in the lab and through pre-implantation genetic diagnostic testing (PGD), the embryos are screened and the embryo that is the genetic match for the sick sibling is implanted into the mother’s womb. The other embryos are typically discarded as they aren’t a suitable match.
This ethics consult asked first the question, “Is it ethical to help a family conceive a child whom they would give up for adoption to their neighbors, but use for marrow donation when the child is physically old enough?” The poll showed that 32 percent said it was ethical and 68 percent said it wasn’t. So, in this particular case, the savior sibling was to be given to adoption at birth but used for their genetic material.
But back to the ethics. In the case of the Nash family, 30 embryos were created, and four rounds of IVF were required for Lisa to get pregnant and deliver Adam, a healthy baby boy without the gene that causes Fanconi’s anemia.
As the ethics consult pointed out, the state rarely looks at the motives of parents when they decide to have their children, but this is different. This isn’t deciding to have children or not to have children, this is deciding to have a particular kind of child to serve the needs of another.
Whether we look for moral guidance from our religious texts or to secular historical documents, it’s important that we remain rooted in the belief in the inherent dignity of all persons.
