I think that was dealt with by my right hon. Friend the Member for Scarborough and Whitby (Mr Goodwill). In all my time in this role previously, I kept going and persevered with the research to try to identify an oral vaccine, because—in reality—if we want to deploy a vaccine on scale in the wildlife population, an oral bait vaccine would be the answer. I have had numerous submissions over the years inviting me to pull up stumps on that research, but I persevered.
However, I am afraid that in the end we could not get there, for the reason that my right hon. Friend pointed out, namely that a badger’s digestive system is too powerful and it breaks down the vaccine. All attempts to find other ways around that were unsuccessful. It is also the case that when such vaccines were deployed in the field, certain badgers would get a lot of the vaccine and others would get none at all, because there would be a propensity for some badgers to take up the bait but not others. So it is not something that we are continuing with at this stage.
I will pick up on a few points that hon. Members have made. The hon. Member for High Peak raised the issue of cows that were heavily pregnant with calves. She is right that it is an absolute tragedy to cull such cows and in fact a couple of years ago I changed the rules in this area, so that a cow that is in the final month of its
pregnancy can now stay on the farm and be placed in isolation. We have even provided that a cow in the final two months of its pregnancy can be isolated, provided that the isolation facilities are sufficiently robust. So I have already changed the rules in that regard, because, as my right hon. Friend the Member for North Shropshire pointed out, it is horrendous when a cow that is about to give birth has to be shot on a farm.
The hon. Lady also raised the issue of the badger population in Derbyshire. The reality is that in in her area in the north of Derbyshire, where badger vaccination is taking place, incidence of the disease in badgers is quite low. However, that is not the case in south-west Derbyshire, particularly along the border with Staffordshire, where there is a high prevalence of the disease in the badger population.
