Understanding the USEF Regulations

As of December 1, 2015, all USEF events will require horses entering the grounds to have documentation of vaccinations prior to competing.

Vaccinations for both Equine Influenza Virus (EIV) and Equine Herpesvirus (EHV) are required.

Vaccines must be administered within six months prior to entering the event grounds.
