§ Mr. GROVES
asked the Minister of Health whether any changes have been made in the methods of manufacturing vaccine lymph in the Government lymph establishment, with a view to the prevention of the risk of post-vaccinal encephalitis; and whether the changes, if any, include the abandonment of the use of rabbits for the purpose of strengthening the lymph supplies?
Sir H. YOUNG
This question has been fully considered, and no such change has been made or is contemplated. I am advised that there is no evidence to suggest that the use of rabbits in the preparation of lymph has any influence on the occurrence of post-vaccinal encephalitis.
