There is disappointment in Wales about that, but I want to continue to talk about the role that vaccines can play.
If cattle could be vaccinated, it would be a step forward that farmers would welcome. It has been said that that might cost £5 a head. Given the amount of medication that cattle receive in a year, £5 is of little consequence. Farmers would certainly leap at the opportunity.
The vaccine that is available now is the BCG vaccine, which a number of us of a certain age have been injected with. The Bacillus Calmette-Guérin vaccine
was developed in Paris between 1910 and 1920. For all the work that has gone on to improve the TB vaccine for human beings, that is the only vaccine that is available. It is only about 60% effective in human beings and in animals.
I accept that a cull has a part to play because infection levels are so severe and all the other methods of control have proved to be ineffective. Farmers have co-operated with DEFRA and the Welsh Assembly Government to increase the number of tests that take place. In Wales, every farm is currently tested every year. If a reactor is detected, tests must be carried out every two months until there are two consecutive clear tests. That is an incredible commitment in terms of labour and expense. Other forms of control have taken place. Pre-testing before movement has proved to be effective, but it is not effective enough to get to grips with this disease that is affecting rural areas.
I believe that the Government have taken a tough decision. The randomised badger culling trials were scientific trials and were never thought to be a practical method of reducing TB. Professor King, who was the Government’s chief scientific adviser at the time, looked at the tests, identified the weaknesses and decided that there were ways to reduce the problem of badgers moving across the cull area. The Government have taken on board all those recommendations and come forward with proposals that I believe will have an impact in reducing and, eventually, eliminating the disease.
