I want to know the answer to the following question:
When did Nigeria launch a bone marrow donation program?
All the background I'm provided with is that "In 2012, a new bone marrow donor program was launched by the University of Nigeria to help people with leukaemia, lymphoma, or sickle cell disease to find a compatible donor for a life-saving bone marrow transplant, which cures them of their conditions.". Is that enough to answer the question?
