Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what research and development initiatives his Department is supporting to accelerate the development of a vaccine for Bluetongue Virus serotype 12.

Defra’s approach to bluetongue is based on the latest scientific evidence and veterinary advice. Disease control measures aim to limit the spread of infection through proportionate and evidence-based control measures. This is reflected in the Great Britain (GB) Bluetongue Virus Disease Control Strategy, which was produced jointly between Scottish and Welsh governments and Defra, and in consultation with experts and industry stakeholders. The GB disease control strategy covers actions that would be considered and implemented in the event any bluetongue serotype was detected, including BTV-12.

The Government also conducts annual targeted surveillance for BTV. This is designed to detect new serotypes of bluetongue virus, including BTV-12 that may be circulating. The annual surveillance uses diagnostic testing protocols at the bluetongue national reference laboratory, The Pirbright Institute, that can detect and differentiate between different serotypes of bluetongue virus including BTV-12. It was through this annual surveillance that the single case of BTV-12 in a single animal was detected on 7 February 2025 on a farm in England and no further cases of BTV-12 have been detected since.

Whilst there are currently no authorised vaccines for BTV-12 in the UK or Europe, Defra regularly engages with manufacturers on bluetongue vaccine availability and supply. The Veterinary Medicine Directorate (VMD) has responsibility for assessing applications submitted by manufacturers for veterinary medicinal products, including vaccines. Following assessment of the supporting data, if the benefits of use outweigh the risks when used in accordance with the approved labelling, a Marketing Authorisation will be issued permitting the sale of the product. The VMD also regulates the distribution and supply of veterinary medicines.
