The Department of Agriculture has released its first bluetongue virus update in response to bluetongue virus serotype-3 being confirmed in a suckler cow in Co Wexford. The first case identified is casting a spotlight on the vaccination of animals.

While vaccines were permitted for use in Ireland since December 2025 there has been no real interest reported up to now due to the fact that the virus was not identified south of the border.

Vets report phone calls in recent days from farmers enquiring about vaccine options with the greater interest especially from pedigree breeders in the southeast.

There are three vaccines permitted for use under licence in Ireland and Northern Ireland for bluetongue virus serotype-3. These vaccines, which have obtained European Marketing Authorisation for use, do not fully stop infection/disease, but the Department highlights that they greatly reduce viremia (spread of infection) and severity of clinical symptoms.

It reports that supplies of Bultavo 3, which it says is licensed for use in sheep and cattle are currently available in Ireland.

It adds that supplies of Bluevac 3 (sheep and cattle) and Syvazul BTV 3 (sheep) will be available soon in Ireland.

The Department also highlighted “the duration of the immunity period guaranteed in the specifications of these vaccines has not been determined to date. Therefore, vaccination cannot be currently used to meet EU standard certification requirements”.
