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

To ask the Secretary of State for Environment, Food and Rural Affairs, when he expects the field trials of the Cattle BCG vaccine to conclude.

Field trials to test a cattle BCG vaccine and accompanying DIVA (Detect Infected amongst Vaccinated Animals) skin test began in June 2021. The next phase of the field trials commenced in September 2025, and we hope to be able to start using an authorised vaccine and companion diagnostic test within the next few years.
