Badger Vaccines

Albert Owen Excerpts

Wednesday 16th October 2013 Westminster Hall

[George Eustice]

We have made it clear that we would never use gassing as a means of controlling the badger population if we thought it was inhumane, but it is in the consultation for research. That does not mean that we will use it, but we will consider further research in this area.

The research is not on animals. It involves laboratory situations and simulated setts to work out how to get gas to go through a sett. The concern is not the gas itself, but the ability to deploy it throughout a sett. I assure the hon. Lady that that is the sort of research that was alluded to in the strategy. There is nothing new about it; it was in our published strategy in July.

Will the Minister give way?

[George Eustice]

I want to make some progress or I will not get to the points raised by my hon. Friend the Member for Morecambe and Lunesdale.

Laboratory studies have demonstrated that vaccinating badgers with BCG can reduce the risk of infection and transmission of the disease. A four-year safety field study of wild badgers showed a statistically significant indirect protective effect in unvaccinated cubs born into vaccinated social groups, but vaccinating a large enough proportion of badgers to reduce transmission of disease and bring about a reduction of TB in cattle would take time to achieve and be costly to deliver, at between £2,000 and £4,000 per sq km per year.

In practice, it is inevitable that not all badgers in an area will be trapped and vaccinated. There is no evidence that vaccination protects already-infected badgers, and there is a risk that badgers from neighbouring unvaccinated areas may act as a constant source of infection. Nevertheless, computer modelling indicates that sustained badger vaccination campaigns could be beneficial in lowering TB incidence in cattle, but quantifying that contribution is likely to need a large-scale field trial, and it would take some years to collect the results.

[George Eustice]

That has been noted, and we will take it on board—[Interruption.] I do not want all hon. Members asking for their constituencies to be a trial area. Vaccination is a potential additional tool to reduce geographical spread of the disease, particularly on the edge of areas. My hon. Friend’s constituency is in not an edge area, but a low-risk area.

Vaccination could complement badger culling by providing a buffer to limit the impact of perturbation. It may also form part of an exit strategy from culling—for example, by vaccinating remaining badgers with the aim of establishing herd immunity in previously culled areas.

[Albert Owen]

I welcome the Minister to his place on the Front Bench. Will he assure the Chamber that his Department is working with the Welsh Government so that we can have some data on their trials, share information and eradicate the problem in the whole United Kingdom? His responsibility covers only England, but such co-operation would help both England and Wales.

[George Eustice]

We are keen to learn lessons from around the country and around the world, so we are looking at the work going on in Wales. I have to say that it is not that encouraging at the moment; a vaccination-only strategy is not seen to be working particularly well, but we will study the results closely. I am also interested in following what is going on in Northern Ireland, where they are trapping and then vaccinating badgers that they believe are not infected and culling those that are. We are also keen to learn lessons from countries such as Australia, which has pursued policies similar to ours.
