Equine Influenza: requirements for mares visiting Shadwell

Posted on: 11th Feb 2019

A series of control measures have been implemented for the 2019 breeding season

Due to the recent EI cases in the UK Thoroughbred population, there is now a significant EI epidemic risk.  Having consulted our own vets, the TBA and the NSFA, we are implementing a series of disease control measures for the impending breeding season, applicable to all visiting mares to the Nunnery Stud.

Whilst infection is being seen in EI vaccinated horses, veterinary advice is clear that vaccination remains essential for disease mitigation as vaccination reduces the severity of clinical signs and decreases the time to recovery, thereby reducing viral shedding and reducing the risk for spread of infection.   Young foals are most at risk from this disease.


  • All mares should be fully vaccinated with a UK licenced EI vaccine and any mare that has not been booster vaccinated within the last 6-months, should receive a booster, unless showing signs of EI infection or being kept in contact with horses showing signs of EI infection (i.e. may be incubating EI). 
  • A Passport Copy with full vaccination pages should be sent to studoffice@shadwellstud.co.uk (A photographed copy is acceptable).  This is required well in advance of covering.  The original passport should travel with the mare.
  • Visiting mares will be accompanied by their own twitch, headcollar and bridle.
  • Visiting mares with a foal at foot should, when possible, send their own handler to hold the foal.

These measures are being implemented to secure the safety and wellbeing of your mares and foals, our stallions and the wider thoroughbred population. 

Thank you for your co-operation and understanding and please do not hesitate to contact our stud office if you have any queries.
