Equine Vaccination Requirements at USEF Licensed Competitions (Triple Rated Shows):
All horses entering the grounds of a USEF- licensed competition must be accompanied by documentation of Equine Influenza Virus and Equine Herpes Virus (Rhinopneumonitis) vaccinations within six months prior to entering the stables.
The intent of this rule is to ensure that all USEF licensed competitions comply with the vaccination guidelines for Equine Influenza and Equine Herpes (Rhinopneumonitis) published by the American Association of Equine Practitioners (AAEP). These guidelines are reviewed by infectious disease experts regularly, and recommend vaccinating competition horses at six-month intervals for both equine influenza (flu) and rhinopneumonitis (EHV-1 and EHV-4). There is not a vaccine that protects against EHM.
Proof of vaccination can be documented by a veterinarian, owner, or owner’s agent. A provision in the rule also recognizes that a horse may be unable to receive either of the vaccinations due to a history of adverse reactions.
