Equine Influenza: Welfare and Vaccination Management

Equine influenza is highly contagious and causes significant respiratory welfare suffering that is largely preventable through vaccination.

Key Facts

Equine influenza viruses evolve rapidly requiring regular vaccine updates
Outbreaks in unvaccinated populations spread rapidly through competitive events
Clinical signs include fever, nasal discharge, harsh cough, and depression
FEI and UK competitions require valid influenza vaccination certificates
Horses require primary vaccination course then regular boosters as per protocol

Welfare Considerations

Horses with influenza experience severe respiratory distress, high fever, and debilitating fatigue that prevents normal activity for weeks. Secondary bacterial pneumonia is a serious welfare complication. Recovery from severe influenza requires extended rest with welfare implications from restricted activity. Outbreaks in naive populations cause welfare harm across many horses simultaneously. Vaccination provides excellent protection and eliminates most influenza welfare burden from vaccinated populations. Vaccination lapses from owner non-compliance create both individual welfare risk and community protection gaps.

What You Can Do

Maintain up-to-date equine influenza vaccination including boosters as required
Follow FEI and competition vaccination documentation requirements
Isolate any horse with respiratory signs and seek veterinary assessment promptly
Avoid contact between unvaccinated horses and competition horses
Support industry surveillance of equine influenza to guide vaccine strain updates
