HC Deb 20 June 1988 vol 135 c421W
Mr. Butler

To ask the Minister of Agriculture, Fisheries and Food what information he has as to whether vaccines in use in the United Kingdom to protect poultry from Newcastle disease will protect against strains found in north America.

Mr. Donald Thompson

I have no reason to suppose that the Newcastle disease vaccines licensed in the United Kingdom, when used in accordance with the manufacturers' instructions, are not effective against strains of the virus found in north America.
