10,000 vaccine doses for equine herpesvirus (EHV) have arrived in Ireland, following an outbreak of the disease on the continent.

The vaccines were ordered following an outbreak of EHV at a high-profile showjumping event in Valencia, Spain.

Following that outbreak, concern was raised that Irish horses competing at events on the continent would bring the virus back here.

The virus spreads quickly and is difficult to treat, though vaccines can provide significant protection. The virus is not thought to present any risk to humans.

The shipment of the vaccine was organised from US suppliers by Coolmore Stud and the Fethard Equine Hospital, with the support of the Department of Agriculture, Food and the Marine.

The department has moved to provide the AR 16 licence required to import veterinary medicines in exceptional circumstances.

The shipment comprised a combination of the Zoetis Equivac and Pneumabort-k vaccines. The vaccine will be made available – at cost – to both the thoroughbred and sport horse industries.

“The outbreak of this potentially fatal virus is causing serious concern to thoroughbred breeders who fear it could spread into Ireland,” remarked Shane O’Dwyer, CEO of the Irish Thoroughbred Breeders Association.

Meanwhile, Joe Reynolds, acting CEO of Horse Sport Ireland, said: “[We] moved quickly to establish protocols to ensure the safe return of horses from overseas to minimize any transmission risk.

“Having access to a vaccine is a very welcome development and we hope to see widespread use throughout our industry, but we must maintain vigilance and continue to follow all veterinary guidance,” he added.

EHV vaccines can only be administered by registered veterinarians. The vaccines will be available for supply to veterinary practices.
