Three vaccines for the bluetongue virus (BTV-3) have been approved for use in Ireland, the Department of Agriculture has confirmed.

A Department spokesperson confirmed to the Irish Farmers Journal multiple vaccines have been licenced.

“There are three BTV-3 vaccines currently authorised for use in Ireland under licence. These are Syvazul BTV 3, Bluevac 3 and Bultavo 3.

“The dose schedule for vaccines will depend on the specific vaccine and the species vaccinated,” they said.

The spokesperson added that farmers should contact their vet to discuss the use of vaccines.

“Cattle and sheep farmers are advised to have a conversation with their veterinary practitioner about whether the use of BTV-3 vaccines is the right choice for their circumstances, in advance of the high-risk summer 2026 season.

“Veterinary practitioners can subsequently advise farmers on the appropriate timelines for vaccination.”

Details for wholesalers or private veterinary practitioners on how to apply for a licence for these vaccines are available online here.

Background

Minister for Agriculture Martin Heydon announced before Christmas that farmers will be permitted to vaccinate cattle and sheep against BTV-3 in 2026.

This comes following an outbreak of the disease in Northern Ireland late last year.

Vaccinations have had mixed results in other countries, with reports indicating they reduce the severity of symptoms, but do not safeguard against infection or transmission.

Those planning on vaccinating against the virus must apply to the Department of Agriculture for a license before obtaining and administering the vaccines.

The Department said it will play no role in setting the pricing or ensuring supplies of the vaccines for farmers.
