I was going to come on to deal with that question but I will touch on it now. Clearly, an effective badger vaccine has a valuable role to play, once the disease is under control. I have discussed this at length in the Republic of Ireland, where they have got the disease well on the way down. Once it can be got to those really low levels—this answers the question from the hon. Member for Cardiff South and Penarth (Stephen Doughty)—there is a definitely a role for a badger vaccine. There is no question about that, but the vaccine has to work.
My worry—I am jumping ahead a bit in respect of Wales here—is that at the moment there is nothing to be gained by vaccinating a diseased animal. Such an animal can continue to be a super-excreter and can continue to spread disease. That is the problem I have with the Welsh experiment. We are very interested in it and we will watch it carefully, but from my travels—I was particularly struck by the Irish experience, and they have done a lot of work on this—I know that the lesson is, “You have to get the disease down to a certain level to get healthy badgers, and then you protect them.” We all want to see healthy badgers living alongside healthy cattle, and the real lesson from Ireland is that the average badger there is now 1 kg heavier than before the cull was begun there. So the Irish have achieved where we want to go; they are getting a healthy badger population, which is exactly what we want, but that is the point at which vaccinations can be deployed. I am not entirely convinced that the Welsh Government are on the right track—I think they are going in too early, because they have not got a grip on the disease—but we wish them well.
Sadly, vaccination is incredibly expensive. The cost of vaccination in Wales stands at £662 per badger or £3,900 per square kilometre per year. Even if the practical difficulties could be addressed, we know that a large-scale programme of badger vaccination would take longer to achieve disease control benefits compared with a programme of culling on a similar scale.
