The first farmer-led programme to vaccinate badgers against tuberculosis is beginning in Cornwall with an aim to prevent transmission of the disease to cattle.
The programme is significant because farmers and scientists have long been at loggerheads over the culling of badgers as a way to control TB. The three-year trial will start with 70 farms and involve farmers trapping, testing and vaccinating badgers, with training provided by scientists. An earlier pilot study of the approach showed TB rates in badgers fell from 16% to zero in four years.
TB can devastate cattle herds and more than 20,000 infected cattle were slaughtered in the last year in England. The badger cull started in 2013 and has killed about 250,000 badgers but has been highly controversial.
