Timeline
11 dated changes to the blood policy, 1945 to 2026. Each entry separates three things: what the Society’s text established, the wording it used, and what this site makes of it.
Verification. 8 of 11 entries have been read in the Society’s own text online. The remaining entries identify where they rely on secondary accounts. Links to the original publications are included where they have been checked.
Transfusion declared a violation of God's law
The Watchtower applies Genesis 9:4 and Leviticus 17 to medical transfusion for the first time. Before this, the same passages had been read as dietary rules that no longer bound Christians.
“…it behooves all worshipers of Jehovah, who seek eternal life in his new world of righteousness, to respect the sanctity of blood and to conform themselves to God's righteous ruling…”
The Watchtower, 1 July 1945, page 201 — quoted via a secondary source; not yet read in the original This site’s reading. The doctrine begins as an interpretation, not a restatement of long-standing teaching. The Society's own 1909 position had been that the Acts 15 prohibitions were a temporary measure for the peace of the early church.
Accepting blood not yet a disfellowshipping matter
The Watchtower says accepting blood does not lead to disfellowshipping. It allows congregation assignments to be withheld.
“…congregations have never been instructed to disfellowship those who voluntarily take blood transfusions…”
The Watchtower, 1 August 1958, page 478 This site’s reading. The absence of disfellowshipping did not mean there were no congregation consequences. This article already allowed restrictions on responsibilities.
Accepting a transfusion becomes a disfellowshipping offence
The Watchtower rules that a member who accepts a transfusion and is unrepentant is to be disfellowshipped — expelled and shunned.
The Watchtower, 15 January 1961, pages 63–64
This site’s reading. The change introduced possible loss of membership for accepting treatment. The article also allowed mercy for a repentant first offence.
Blood fractions in vaccines left to conscience
The Watchtower allows individual members to decide whether accepting blood fractions used in vaccination violates their conscience.
The Watchtower, 1 November 1961, page 669 — effect documented by secondary sources; original not yet read
This site’s reading. This is an early example of the distinction later drawn between blood components and products extracted from them.
Hemodilution and cell salvage left to conscience; stored own blood still refused
The Watchtower rejects storing a patient’s own blood for later transfusion. It discusses dialysis, bypass, hemodilution and cell salvage as decisions of conscience, and explicitly says that uninterrupted flow is not the deciding issue.
“…Some Christians have permitted this if the equipment is not primed with stored blood.”
The Watchtower, 1 March 1989, pages 30–31 This site’s reading. The distinction concerned whether blood remained part of the person, as they understood it. Describing this as a simple ban on interrupted circulation misstates the article.
Awake! publishes “Youths Who Put God First”
The issue reports the deaths of Adrian Yeatts, Lenae Martinez and Lisa Kosack following refusal of blood treatment and praises their religious convictions.
“In former times thousands of youths died for putting God first. They are still doing it, only today the drama is played out in hospitals and courtrooms, with blood transfusions the issue.”
Awake!, 22 May 1994, page 2 This site’s reading. The account of Lenae specifically names red cells and platelets. Those products are now personal choices; the article cannot establish what her outcome with transfusion would have been.
Sanction reworded: “deemed to have disassociated”
A Watch Tower press statement describes a member who accepts blood as having disassociated themselves by their action, rather than being disfellowshipped by a judicial committee. The practical consequence — loss of membership and shunning — is the same.
Watch Tower Society press statement, 14 June 2000, as reported — effect documented by secondary sources; original not yet read
This site’s reading. The revised terminology attributed the end of membership to the member’s action. Secondary accounts report that shunning continued.
Fractions of any primary component left to conscience
The Watchtower states that whole blood and the four primary components — red cells, white cells, platelets, plasma — are refused, but that fractions derived from any of them are a matter for each member's conscience.
“…when it comes to fractions of any of the primary components, each Christian, after careful and prayerful meditation, must conscientiously decide for himself.”
The Watchtower, 15 June 2000, pages 29–31 This site’s reading. Products made from donated blood, in some cases from thousands of donors, become acceptable while the blood they came from remains forbidden.
The post-2000 position restated with a chart
The Watchtower restates the position: accepting whole blood or any of the four primary components “violates God's law”; fractions are for each member to decide. A chart distinguishes the two.
“Jehovah's Witnesses hold that accepting whole blood or any of those four primary components violates God's law.”
The Watchtower, 15 June 2004, pages 29–31 (“Questions From Readers”) This site’s reading. The September 2026 policy reverses this prohibition for the four components.
A patient's own blood becomes a personal decision
2026 Governing Body Update #2 states that the Bible does not comment on the use of a person's own blood in medical and surgical care, and that each member must decide for themselves — including pre-operative storage, expressly refused in the 1989 article.
“Christians are not under the Mosaic Law. However, we obey the apostolic command to “abstain from blood.” Furthermore, the Bible does not comment on the use of a person's own blood in medical and surgical care.”
2026 Governing Body Update #2, 20 March 2026, as quoted in the September 2026 “Questions From Readers” This site’s reading. This ends the prohibition on storing a patient’s own blood in advance. Uses during surgery had already been left to conscience in the 1989 article.
The four primary components become a personal decision
2026 Governing Body Update #6 extends the March reasoning to red cells, white cells, plasma and platelets from another person. Transfusion of another person’s whole blood remains prohibited.
“…the Governing Body has decided that this same principle applies to the four primary components of whole blood—red cells, white cells, plasma, and platelets—that are derived from another person's blood. Therefore, each Christian must make his own personal decision about the use of these four primary components in all medical and surgical care.”
“Questions From Readers”, jw.org, 18 September 2026 This site’s reading. This changes the policy for all four main donor components. The accompanying article does not discuss deaths following refusal under the earlier rule.
