Behringwerke AG (German blood product manufacturer)
A pasteurization procedure is developed and licensed in Germany by blood product manufacturer Behringwerke AG. It involves heating factor concentrates at 60C for ten hours. An article demonstrating the efficacy of the pasteurization process is published the same year.

Note: Other manufacturers are reluctant to adopt this technique over concerns regarding:

  • 50-90% loss of yield,
  • factor supply could be in jeopardy
  • pasteurized factor will cost ten times more
  • concerns over the effectiveness of inactivating non-A non-B hepatitis
  • patients might develop inhibitors.

Miss Cunningham / BTSB - HT3
It is now known (in 1987) that dry heating is ineffective in preventing Non-A Non-B Hepatitis. In a scientific meeting, Miss Cunningham, discusses various methods of heat treatment, and notes that the British protocol of pasteurisation of 80 Centigrade for 72 hours is effective against transmission of Non-A, Non-B Hepatitis and AIDS.
