The main objective of this project is to identify whether it is really ethical and legal to have a ‘medicine baby' so that it can be a donor for its ill sibling. The fact that the baby is not conscious and cannot give its consent for the use of its cells requires us to ask to what degree this is an ethical method and at what point it ceases to be so. Secondary objectives are to identify public opinion on this issue, and to find out about the bone marrow transplant process.
