Leaders of Jehovah's Witnesses are modifying their prohibition on receiving blood transfusions on religious grounds, now allowing members to decide whether to allow their own blood to be drawn and stored in advance for such things as a scheduled surgery with a risk of significant blood loss.
But the organization is retaining its wider prohibition against receiving transfusions of others' blood — a procedure routinely used with patients after accidents, violence or other blood loss. This long-held prohibition is one of the most distinctive and controversial teachings of the movement, which is headquartered in New York state and well-known for its assertive public proselytizing.
