We recommend the owners of all horses, ponies and donkeys to regularly vaccinate their animals in order to prevent some serious and potentially life-threatening diseases. 

Competition horse owners should ensure that their horse or pony is vaccinated according to the rules of the appropriate sporting governing bodies under which they are competing (e.g. FEI, British Eventing, British Showjumping, British Dressage, British Riding Clubs, etc.). Vaccination rules will differ amongst these organisations and passports may be requested and checked at any time during events. It is the owner’s responsibility to ensure that the vaccination record is up to date and any lapse in the vaccination history, even by a few days, will be considered by a sport’s governing body to be a breach of their rules. This may result in the horse being unable to compete or penalties being imposed.


Clostridium Tetani bacteria causes tetanus, often fatal disease once contracted through open wounds from the soil. It causes rigid paralysis of the muscle, leading to an inability to move, eat, swallow and breath.

Horses and foals can be vaccinated from 6 months of age.

  • First injection: day 1
  • Second booster: 4 Weeks Later
  • Third booster: no longer than 17 months from the primary course
  • Annual Booster: maximum interval 2 years


Influenza or flu is a highly contagious virus that spreads quickly via the respiratory system. Signs include lethargy, exercise intolerance, fever and nasal discharge. Vaccination against influenza reduces the clinical signs and viral shedding associated with the virus.

Horses and foals can be vaccinated from 6 months of age. We highly recommend using the combined flu & tetanus course.

  • First injection: day 1
  • Second booster: 4 weeks later (given between 21-92 days after 1st vaccine)
  • Third booster: 5 months later (given between 150-215 days after 2nd vaccine)
  • First annual booster: no more than one year after the 3rd vaccine (ideally 17 Months after 2nd vaccine because of tetanus booster)
  • Subsequent annual boosters: no more than one year


Herpes vaccination helps protect the horse from the strains EHV1 and EHV4. It is often used in broodmares to minimise the risk of abortion during the later stages of pregnancy or in youngsters and competition horses to reduce the chance of respiratory infections, nasal discharge occurring.

  • Broodmares: injection in the 5th month, 7th month and 9th month of pregnancy
  • Youngsters & other horses: from 5 months of age followed by a second injection after 4-6 weeks. Booster every 6 months.

ADVERSE REACTIONS are generally rare but there are few points to consider:

  • SWELLING; a diffuse hard or soft swelling may occur at the injection site, usually regressing within a week.
  • STIFFNESS; pain at the site can occur and may result in temporary functional discomfort (stiffness) of the neck or front legs.
  • FEVER; rare, sometimes accompanied by lethargy and inappetence, may occur for 1 day, and up to 3 days in exceptional circumstances.
