Bovine Tuberculosis

Lord Soulsby of Swaffham Prior Excerpts

Tuesday 23rd October 2012 Lords Chamber

[Lord Soulsby of Swaffham Prior]

My Lords, in view of the great success in controlling rabies in foxes in western Europe with an oral vaccine, has much thought been given to the production of an oral vaccine for TB in badgers? I realise, of course, that the organisms are entirely different; one is a virus and one is a bacterium. However, surely the same process of trying to select an organism that is protected before it gets into the gut and immunises the badger is worthy of investigation. Can the Minister give some indication of some of the work that is going on, if any, on the production of an oral vaccine similar to the one developed for fox rabies?

[Lord De Mauley]

I am grateful to my noble friend because this is an important subject into which considerable work is going on. The evidence that he has referred to will of course be taken into account. Progress on the development of an effective oral badger vaccine relies, of course, on scientific breakthroughs in this field, and it is uncertain in outcome and timing. Compared to an injectable vaccine, an oral vaccine is technically more difficult to formulate, as my noble friend alluded to, and it requires bait, which encourages the uptake of the vaccine by badgers and minimises the potential of other species to eat it. Developing an oral vaccine against TB in badgers is proving more difficult than originally hoped, which means that I cannot say with certainty when one might be available for use in the field.
