HC Deb 01 May 1952 vol 499 c114W
103. Mr. Peter Freeman

asked the Minister of Health how many calves were used last year for the purpose of the manufacture of vaccine; whether they are allowed to recover after the injection of the smallpox virus; how often they are again injected after recovery; what time is allowed to elapse between any two such operations; and for what purposes the carcases are used after such inoculations.

Mr. Crookshank

I am obtaining particulars from the commercial makers of vaccine lymph who use calves for this purpose, and will send them to the hon. Member as soon as I can.
