I can assure my hon. Friend that we have considered the experience of countries that have used vaccination extensively, and there were problems in every case. Vaccination is an option, and we have contingency plans, as is right and proper. Sometimes it is right also to challenge conventional thinking about the way to deal with issues, and I can assure my hon. Friend that we are not afraid to do so.

Vaccines are not a panacea and there are problems with them. There is resistance to the idea within farming, and there is no consensus of approach on their use, which would be important if they were to be used. There are also problems with trade, identification and potential consumer resistance. Nevertheless, we need to consider these matters carefully and keep them under review.
