Zoetis Introduces Complete Core Equine Disease Vaccine

New Core EQ Innovator™ helps protect horses from all five core equine diseases in one smooth vaccine.

Core EQ Innovator is the first and only equine vaccine to contain all five core equine disease antigens—West Nile, Eastern and Western equine encephalomyelitis, tetanus and rabies—in one vaccine. undefined

Today, Zoetis introduced Core EQ Innovator™, the first and only equine vaccine to contain all five core equine disease antigens—West Nile, Eastern and Western equine encephalomyelitis, tetanus and rabies—in one smooth vaccine. 

As defined by the American Association of Equine Practitioners and the American Veterinary Medical Association, these diseases are designated as core because all horses are at risk for exposure, all have a high fatality rate, and some may present a potential human health risk.1

“Viral respiratory and neurologic diseases are the leading preventable causes of death in horses,” said Jacquelin Boggs, DVM, MS, ACVIM, senior veterinarian, Equine Technical Services at Zoetis. “While annual vaccination against the core equine diseases has long been an established standard of care, Core EQ Innovator will simplify compliance and help provide protection to all horses against these deadly diseases. We trust this vaccine will better equip veterinarians with the tools they need to help protect the health and well-being of horses.”

Annual vaccination is the only way to help protect horses from the deadly core equine diseases. Core EQ Innovator is available only through veterinarians to provide additional assurance horses are vaccinated properly.

Core EQ Innovator provides a safe and effective immune response against the five core equine disease antigens as demonstrated in safety and efficacy trials. The vaccine has been field tested in more than 1,000 horses with 99.7% of horses being reaction-free.2,3 With a convenient 1-mL dose size, the vaccine is safe for use in healthy horses 3 months of age or older.

All of the disease antigens in Core EQ Innovator are backed by the Zoetis Equine Immunization Support Guarantee. The guarantee provides horse owners and veterinarians peace of mind through unparalleled vaccination support, including diagnostic testing and treatment.

The addition of Core EQ Innovator enriches the best-in-class portfolio of equine vaccines from Zoetis. Core EQ Innovator will be available to veterinarians through their Zoetis representative and distribution partners. Horse owners are encouraged to contact their veterinarian for more information or visit CoreEQInnovator.com.
