USEF Equine Vaccination Rule
In January, the United States Equestrian Federation (USEF) Board of Directors approved an addition to the rulebook, which outlines equine vaccination requirements at licensed competitions. Beginning Dec. 1, 2015, all horses entering the grounds of a Federation-licensed competition must be accompanied by documentation of equine influenza virus and equine herpesvirus (Rhinopneumonitis) vaccinations within six months prior to entering the stables.
