Jehovah’s Witnesses have made a major adjustment to their blood policy. Members can now personally decide whether to accept red cells, white cells, plasma or platelets, and whether to donate blood specifically for use as components or fractions. The longstanding refusal of whole-blood transfusions remains unchanged. For Nigerian Witnesses, this could widen the medical choices available during surgery, emergencies and other hospital treatment, while leaving the final decision to each individual’s conscience. The key change is significant: what was previously prohibited for the four main blood components is now a personal religious decision.
