§ 103. Mr. Peter Freemanasked 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. CrookshankI 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.
