Jehovah's Witnesses Expand Blood Transfusion Doctrine, Allow Allogeneic Derivatives

The Jehovah's Witnesses have modified their doctrine to permit allogeneic blood derivatives, building on an earlier 2026 authorization of autotransfusions. This marks the first major doctrinal shift on blood products since World War II. The change could affect medical protocols for adherents and hospital policies, though the exact scope and implementation remain unclear.
