Equine influenza is a highly contagious viral disease that usually affects young horses. It causes fever as well as coughing and nasal discharge. Vaccination against equine influenza is compulsory for horses participating in most competitions and clinics highly recommend it for all horses. The vaccine is often paired with the tetanus vaccine. The protocol is composed of two injections for the primo vaccination separated by between 3 weeks and 3 months, followed by a booster at 5 months. Following boosters are performed every 6 months in young horses and should not be separated by more than a year.
