HC Deb 11 April 1989 vol 150 c437W
Mr. Ron Davies

To ask the Minister of Agriculture, Fisheries and Food what further work is necessary before field trials can begin of the tuberculosis vaccine for badgers which has been developed by the Middlesex hospital.

Mr. MacGregor

Further work is necessary to check whether accidental contact with the vaccine could lead to desensitisation of cattle infected with tuberculosis so that they would no longer be reactors when tuberculin tested.
