I am surprised by the right hon. Gentleman's uncharacteristic suggestion that we should rule something out and that we should not have a debate on whether there is a role for vaccination. I stress that vaccination is not a panacea: there are severe downsides to its use. It is not the Majority view in the veterinary or scientific world, although there is, of course, a minority view to the contrary. It is right and proper that we hold the option open, but it is most important that we control and eradicate the disease. The current policy appears to be bearing down on it, so it has to be the priority; vaccination is currently of secondary importance.
