Letter from Professor Blackburn, The University of Sheffield to Sir George Godbar, DHSS. Professor Blackburn was asked by the UKHCDO to write to the DHSS to request a committee be set up to discuss the supply of materials for haemophilia and related disorders. Professor Blackburn confirms the available options and advises that due to a shortage in the domestic supply of freeze dried product there is an urgent need to purchase imported commercial products.
