asked the Minister of Health how much money is paid to the Lister Institute for vaccine lymph supplied by the institute for the purpose of public vaccinations.

The payment is £10,000 a year for the supply of lymph up to a total of 500,000 doses annually, with a payment of twopence per dose for any supply additional to this.

asked the Minister of Health, why sheep are used in the manufacture of vaccine lymph at the Lister Institute instead of calves; and whether the process in the case of sheep is similar to that formerly used at the Government lymph institute in regard to calves.

I understand that the Lister Institute prefers sheep to calves because they are more readily obtainable, easier to keep clean, hardier, and not subject to tuberculosis disease, though post-mortem examination of every animal used eliminated the latter risk when calves were used. The answer to the last part of the Question is "Yes, Sir."
