ADHB Farming Podcast: When will a BTV-3 vaccine be found?

Participating in the Agriculture and Horticulture Development Board Farming Podcast offered a unique platform to discuss the emergence of the BTV3 strain of blue tongue virus in the UK, a subject of great concern to the livestock farming community and one that demands a scientific approach for resolution.

The recent detection of BTV3, initially in Kent and subsequently in other regions, underscores the need for immediate and informed action. This strain, spread by midges, presents a new challenge, as existing vaccines do not offer cross-protection against it. The development of a new vaccine is imperative, yet it is complex process, as I discussed on the podcast.

The Vaccine Development Process

The journey toward creating a vaccine begins with the identification of the virus itself. This involves not only recognising BTV3 but also understanding its genetic makeup and how it interacts with the host’s immune system. From there, the development process is a linear series of steps, starting with the creation of a vaccine candidate and moving through various stages of testing for safety, efficacy, and quality.

During the podcast, Dr. Carrie Button from the Pirbright Institute provided invaluable insights into the scientific efforts underway to develop a vaccine against BTV3. She highlighted the limitations of using live attenuated vaccines from endemic regions, such as South Africa, due to safety and regulatory concerns. Dr. Button’s explanation of the challenges in adapting these vaccines for use in the UK was particularly enlightening, emphasising the need for a vaccine that is both effective and safe for our livestock and environment.

Regulatory Hurdles

The regulatory process for vaccine approval is rigorous, focusing on three main components: quality, safety, and efficacy. Quality assurance involves ensuring the vaccine’s components are pure and that its production is consistent. Safety assessments are crucial to ensure the vaccine does not harm the animal, handlers, consumers, or the environment. Lastly, efficacy tests confirm that the vaccine protects against the disease as intended. These steps, while necessary, add time and complexity to the vaccine development process.

Dr. Mandy Nevel from the AHDB discussed the organisation’s response to the outbreak and the importance of vigilance among farmers. Her insights into the practical aspects of disease management and prevention highlighted the critical role of the agricultural community in mitigating the spread of BTV3.

Looking Forward

The scientific community’s response to the BTV3 outbreak is a testament to the importance of collaboration in addressing agricultural challenges. The development of a new vaccine is not just a scientific endeavour but a collective effort that involves researchers, regulatory bodies, pharmaceutical companies, and the farming community.

As we advance in our understanding of BTV3 and work towards a viable vaccine, the insights shared by my fellow guests on the podcast underscore the multifaceted approach required to combat this disease. The path ahead is complex, but with continued research, collaboration, and communication, we can protect our livestock and ensure the sustainability of the farming industry in the UK
