The battle against bovine tuberculosis (BTB) in England is entering a new phase, with a focus on cattle vaccination and a phased end to badger culling. This strategy, developed by a diverse group of experts, aims to eradicate BTB by 2038, marking a significant shift in approach. The plan acknowledges the limited impact of culling badgers and emphasizes the critical role of cattle in the disease's spread.
One of the key innovations is the introduction of cattle vaccination, a measure long advocated for its potential to revolutionize BTB control. However, this approach faces challenges due to the European Union's ban on vaccination, which complicates the identification of infected animals. To address this, the "Diva" test is set to be rolled out, ensuring accurate detection. The strategy's success hinges on international cooperation, with government officials working to gain acceptance for the vaccination and test from other nations and the World Organisation for Animal Health by 2030.
The strategy's emphasis on cattle vaccination is supported by scientific evidence. Professor James Wood highlights the 15-fold higher transmission rate between cattle compared to wildlife, making cattle the primary focus. Studies in Ethiopia demonstrate the vaccine's 89% efficacy, providing a compelling case for its implementation in England. The vaccine's license application has been submitted, and the strategy's advocates, including John Cross, a livestock farmer and chair of the Bovine TB Partnership, believe it represents a "game-changing" step towards TB freedom.
However, the strategy's success also relies on addressing the political and economic implications. Paul Tompkins, the deputy president of the National Farmers' Union, emphasizes the ongoing devastation of BTB on farming families and the need for urgent action. The plan's implementation will require diplomatic efforts to ensure the continued export of dairy products, as the vaccination and Diva test are introduced.
Despite the optimism surrounding the strategy, there are challenges and uncertainties. The effectiveness of the badger cull, which has already ended in most of England, remains a subject of debate. Professor Wood acknowledges the difficulty in quantifying the cull's impact, given the concurrent improvements in biosecurity and testing. The strategy's success will depend on a comprehensive approach, balancing the need for rapid progress with a realistic understanding of the disease's complexities.
In conclusion, the new strategy for BTB eradication in England represents a significant shift towards a more targeted and scientifically-driven approach. While the challenges are substantial, the potential for success is high, especially with the introduction of cattle vaccination and the Diva test. The strategy's advocates are confident that it will accelerate progress towards TB freedom, but the journey will require careful navigation of political, economic, and scientific hurdles.
