The taintedblood Timeline  -  what really happened...

In a DHSS letter of August 1985, the Deputy Chief Medical Officer, states that it was apparent that certain Haemophilia Centres were still using Factor VIII that had not been heat-treated:

Dr E. Harris: (DCMO) I understand that all commercial Factor VIII imported into this country is also heat treated. There would thus appear to be no longer any need to use un-heat-treated Factor VIII concentrate.

Note: This statement turned out to be overconfident and wrong, as within only six months, Armour Batch A28306 infects haemophiliac boys in the Birmingham area (Lindsay Tribunal Report, pg 53) and by March 1986, Armour has to be questioned by the DHSS about the efficacy of its heat-treatment methods. (Krever Report, Volume 3, Part IV, Chapter 33, page 933).

Dr John Petricciani, the director of the Division of Blood and Blood Products of the FDA, writes in The Lancet that:

"Infectious LAV/HTLV-III [HIV] is unlikely to be present in currently licensed heat-treated factor concentrates, and that the use of such factor concentrates should not result in additional cases of AIDS in persons with hemophilia."

Note: See the Find Related Entries link below to learn why this article was so misleading.

A 3rd case of seroconversion in an haemophiliac is associated with the use of Armour's H.T. Factorate.

Armour batch A28306 is the likely cause of HIV infection in a UK haemophiliac on 21 February 1986.

(The Armour product was heat treated at 60° Centigrade for 30 hours and was made from plasma of untested donors. This product is associated with up to 12 cases of late seroconversion.)

Background: Only a week or so earlier, the Government's CMO, (Chief Medical Officer), Dr Donald Acheson, dismissed evidence that Dutch patients had been infected by heat-treated Factor 8, and assured British haemophiliacs that US supplies were safe.

NOTE: It should be noted that the Amsterdam-based physicians had reported in the Lancet that their patient had been given exclusively heat-treated Factor VIII originating from the United States.

The untested plasma that Armour batch A28306 originates from was made into similar types of Armour product which infect haemophiliac boys in the Birmingham area.

DHSS questions Armour about the efficacy of its heat-treatment methods.

Departmental staff meet with Armour officials to review the data on inactivating viruses.

Another 2 seroconversion cases are reported in persons with haemophilia in the UK who have been treated with Armour's H.T. Factorate.

DHSS staff meet again with Armour officials. At this meeting, Armour agrees to voluntarily withdraw all H.T. Factorate from the U.K. market.

The company also agrees to relinquish its product licences for all factor VIII concentrate products.

Armour voluntarily withdraws heat-treated factor VIII which is suspected of causing seroconversion in Canadian hemophiliacs.

The request from Armour for an indemnity from BTSB is discussed at a BTSB Board Meeting. The CEO explains that this request has very serious implications for the Board. The production of factor VIII will cease on 31st December 1988, after which the Board will be faced with a choice of Monoclate or pasteurised product. Both products have implications on the goal of self-sufficiency.

Product Liability Acts are about to become law.
