Details

Defra’s Secretary of State has permitted the use of 3 unauthorised bluetongue serotype 3 (BTV-3) vaccines within the United Kingdom, subject to licence. Veterinarians should read the advisory note before prescribing any BTV-3 vaccine.

Although these vaccines are not authorised, the Veterinary Medicines Directorate (VMD) has assessed them. They consider the vaccines to be of a consistent quality and safety, and efficacy has been demonstrated. Therefore, they meet the administration criteria under Schedule 4 of the Veterinary Medicine Regulations 2013 (VMR 2013).

Unlike the authorised vaccines for other BTV serotypes, the BTV-3 vaccines claim to reduce viraemia rather than prevent it. This means they may not prevent animals from being infected or infectious, but (depending on the vaccine) their claims include reduction or prevention of clinical signs experienced or mortality.

As this is the first time that Defra has used this power, the UK Chief Veterinary Officer asks all veterinarians to record all vaccine use and inform relevant authorities of any adverse effects.
