Disease prevention is a key part of horse health. The trusted INNOVATOR vaccine line from us at Zoetis helps ensure your horse’s health is best-in-class. 


  • CORE EQ INNOVATOR — the first and only vaccine to help protect against all potentially fatal core equine diseases in one injection

All horses are exposed to the threats that cause West Nile virus, Eastern and Western equine encephalomyelitis, tetanus and rabies. Help provide the protection your horse needs by vaccinating with CORE EQ INNOVATOR each spring.

Respiratory diseases, such as influenza and herpesvirus, were leading causes of death in horses in 2015.1,2 If your horse travels or lives with horses who do, ensure they are protected. Trust FLUVAC INNOVATOR® to help provide your horse with protection against key equine influenza virus strains as well as equine herpesvirus (EHV 1 and EHV 4).

Zoetis confidently stands behind its vaccines with the Equine Immunization Support Guarantee (ISG).When horses are vaccinated by a veterinarian with CORE EQ INNOVATOR, FLUVAC INNOVATOR and/or WEST NILE-INNOVATOR® vaccines, under the Equine Immunization Support Guarantee, Zoetis may help determine the cause of illness should your horse become sick and may help cover treatment costs.*
