In a partial reversal of longstanding doctrine, Jehovah's Witnesses have relaxed their prohibition on donated blood in medical treatment. According to STAT, the religious organization now permits the use of blood-derived products. The change stops short of allowing traditional whole-blood transfusions, which remain banned.

Clinicians caring for Jehovah's Witnesses patients may need to distinguish between acceptable blood-derived therapies and whole-blood transfusions under the revised policy. The nuanced stance reflects an attempt to accommodate modern medical options while preserving the group's core prohibition.
