Bluetongue serotype 3 (BTV-3) vaccine: information for keepers
Source: gov.uk (2025-07-31)

Information about the availability of BTV-3 vaccines for animal keepers.

If your livestock have been vaccinated for BTV-3 you still need to comply with all BTV-3 movement and testing requirements.

Three BTV-3 vaccines have been permitted for use. Two of these have been granted a marketing authorisation by the Veterinary Medicines Directorate (VMD), and the third is unauthorised. You can only use these vaccines if your use is compliant with a valid licence or declaration.

For more information on the BTV-3 vaccines including permits and licences visit Bluetongue serotype 3 (BTV-3) vaccination (https://www.gov.uk/government/collections/bluetongue-serotype-3-btv-3-vaccine-permits).

Where you can use the BTV-3 vaccines

You can use these vaccines in England, Scotland, Wales and Northern Ireland. In:
- England you must comply with the legal conditions of the general licence for England (https://www.gov.uk/government/publications/general-licence-for-bluetongue-serotype-3-btv-3-vaccine), including reporting vaccine use (https://www.gov.uk/guidance/report-your-use-of-the-bluetongue-serotype-3-btv-3-vaccine)

- Northern Ireland you must apply for a specific licence for Northern Ireland (https://www.daera-ni.gov.uk/publications/application-form-specific-licence-livestock-keeper-obtain-bluetongue-btv-3-vaccine) and comply with the legal conditions within the licence, including reporting vaccine use in Northern Ireland (https://www.daera-ni.gov.uk/publications/livestock-keeper-return-btv-3-vaccination)
Important information for vets

In addition to your responsibility to inform the relevant authorities of any adverse effects that you notice, the UK and Wales, Scotland and Northern Ireland Chief Veterinary Officers have published an:
- advisory note for England (https://www.gov.uk/government/publications/bluetongue-serotype-3-vaccine-advice-for-veterinarians)
- advisory note for Wales (https://www.gov.wales/prescribing-btv-3-inactivated-vaccine-guidance-vets)
- advisory note for Scotland (https://www.gov.scot/publications/bluetongue/documents/)
- advisory note for Northern Ireland (https://www.daera-ni.gov.uk/publications/cvo-letter-pvps-re-voluntary-pre-emptive-use-bluetongue-serotype-3-btv-3-vaccines-northern-ireland)
These ask for your cooperation to keep records of the bluetongue vaccine doses that you order, supply and prescribe.

Vets in England, Scotland and Wales should notify Defra within 7 days of prescribing the vaccine using the prescription of the BTV-3 vaccine reporting form (https://www.gov.uk/guidance/report-the-prescription-of-a-btv-3-vaccination).

In Northern Ireland, vets should record BTV-3 vaccine use each month (https://www.daera-ni.gov.uk/publications/veterinary-practice-return-btv-3-vaccination) and return the completed record to their local DAERA Direct Office.

Deciding whether to vaccinate

Work with your vet to determine if BTV-3 vaccination is right for your animals.

Reasons you might want to vaccinate include:
- having high-value stock, high production units, rare breeds or smallholdings
- if the impact of reduced productivity, abortions or reduced animal welfare could affect conservation efforts
You can also check the Battle Bluetongue campaign (https://ruminanthw.org.uk/bluetongue-virus-information-for-vets/battlebluetongue-vet-information/) for more information on making vaccination decisions.

Keep a record of your vaccinations

Your vet must prescribe the vaccine, but you, the animal keeper, can administer the vaccine to your animals. You are reminded to use safe practice.

In England and Wales when you use a BTV-3 vaccination you must:
- keep a record of every animal you vaccinate – the information you need to record is on the general licence
- keep these records for at least 5 years
- provide details including the individual animal IDs and vaccine you use to Defra (https://www.gov.uk/guidance/report-your-use-of-the-bluetongue-serotype-3-btv-3-vaccine) within 48 hours of vaccinating
In Scotland when you use a BTV-3 vaccination you must:
- provide details including the individual animal IDs and vaccine you use to Scottish Government – report vaccinating cattle and sheep on ScotEID (https://www.scoteid.com/) within 48 hours of vaccination
- report vaccinating other susceptible species on GOV.UK (https://www.gov.uk/guidance/report-your-use-of-the-bluetongue-serotype-3-btv-3-vaccine) within 48 hours of vaccination
In Northern Ireland when you use a BTV-3 vaccination you must return the livestock keeper form (DAERA) (https://www.daera-ni.gov.uk/publications/livestock-keeper-return-btv-3-vaccination) to your local DAERA Direct Office within 5 working days of vaccinating.

Moving vaccinated animals

All movement controls and trade restrictions (https://www.gov.uk/guidance/bluetongue-movement-licences-and-designated-slaughterhouses) are the same for BTV-3 vaccinated animals as for unvaccinated animals.

You should not test vaccinated animals as part of a pre-movement test in bluetongue zones until at least 7 days after their vaccination. This will prevent interference with BTV-3 monitoring.

There is some risk that individual countries could take a precautionary approach regarding trade in products from vaccinated animals. Defra does not judge this to be a major concern, particularly given current use of these vaccines on the continent. There are no known trading restrictions on products of animal origin from vaccinated animals. If restrictions were applied, we would engage with trade partners to try to mitigate these.
