Vaccines stimulate an immune response by tricking horses’ bodies into believing that they are being attacked by a disease and creating antibodies and killer cells which will enable a strong, quick immune response should natural infection pursue.

Equine Influenza

The equine influenza (EI) virus is endemic in GB and spreads rapidly between individuals. Even horses that do not leave their home or mix with other horses may be at risk because the virus can spread over very long distances in airborne droplets. The disease is commonly fatal to foals, donkeys and mules.

CLINICAL SYMPTOMS

  • Fever
  • Lethargy
  • Inappetance
  • Nasal /ocular discharge
  • Deep dry cough

SOME HORSES DEVELOP

  • Myositis (muscle disease)
  • Myocarditis (inflammation of the heart muscle)

FEW HORSES DIE DUE TO

  • Pleuropneumonia
  • Purpura

There are 4 different equine influenza vaccinations on the market that are authorised, and in common use by equine vets in the UK.

Only one of these vaccines, that used by New Forest Equine Vets, has been updated to include the Florida Clade 2 strain of flu which has been responsible for almost all outbreaks in the UK since 2011.  It is the only vaccine that complies with OIE regulations.

Vaccination Schedules

Ensuring your horse if properly protected

Livery yards and competition authorities generally require that horses are vaccinated against equine influenza (EI) to comply with Jockey Club Rules which stipulate that:

  • the 2nd Vaccine is administered 21-92 days after the 1st vaccine.
  • the 3rd Vaccine is administered 150-215 days after the 2nd vaccine.
  • the first annual booster is administered within 365 days of the 3rd vaccine
  • boosters thereafter are administered within 365 days of the last vaccination.

These dates, however, are different to the dates recommended by the vaccine manufacturers to provide effective immunisation.

To comply with the ‘rules’ and ensure proper protection against equine influenza (EI) and tetanus (T), at New Forest Equine Vets we recommend the following schedules:

Equine Influenza and Tetanus

  • 1st vaccine: From 6 months of age
  • 2nd vaccine: 4-6 weeks later
  • 3rd vaccine: 5 months later

Annual boosters: EI only within 365 days then alternate between EI / EI and T every year

Tetanus

  • 1st vaccine: From 6 months of age
  • 2nd vaccine: 4-6 weeks later
  • Annual boosters: 2 years later
  • Then every 2nd year

* Horses competing under FEI regulations must in addition be vaccinated against EI within 6 months of the 3rd vaccine and then receive EI boosters every 6 months.

Ensuring foals are adequately protected by maternally derived antibodies

Vaccination schedule for broodmares (EI and T) to provide immunity to the foal

Vaccinated pregnant mares:

  • Booster 4-6 weeks before foaling.

Unvaccinated pregnant mares:

  • 1st vaccine 4-6 weeks before 2nd vacciner
  • 2nd vaccine 4-6 weeks before foaling
