HL Deb 07 December 1989 vol 513 c1117WA
Lord Winstanley

asked Her Majesty's Government:

What was the nature and result of the clinical trials into stocks of Factor VIII and Factor IX made by the Blood Products Laboratory at Elstree from unscreened blood donations which was referred to in the answer to Lord Winstanley's Question on 18th December 1986 (HL Deb. col. 345).

Baroness Hooper

The clinical trials in question were prospective studies on the virological safety of heat-treated Factor VIII and IX and these studies showed no evidence of transmission of either non A non B hepatitis nor HIV whether or not screened or unscreened donations were used. After December 1986 the studies did not involve the issue of Factor VIII or Factor IX from unscreened plasma.
