FluVac Innovator 4, a member of the FluVac Innovator line of equine vaccines, is moving to the Pfizer Animal Health label after the acquisition of Wyeth and Fort Dodge Animal Health in 2009. The vaccine is now manufactured by Pfizer Animal Health and features an updated label and packaging.

FluVac Innovator 4 vaccines are designed to aid in the prevention of equine influenza, Eastern and Western equine encephalomyelitis, and tetanus. The American Association of Equine Practitioners recommends equine influenza vaccination every six months for at-risk horses, which includes horses under six years of age, geriatric horses, and horses that might be frequently exposed to equine influenza virus (EIV) at shows or other equestrian events.

Andrea Wright, DVM, MVSc, marketing manager of equine biologicals for Pfizer Animal Health, said "Pfizer Animal Health stands behind the established reputation and efficacy of these vaccines."

The FluVac Innovator vaccines are included in the Equine Immunization Support Guarantee, which provides up to $5,000 for reasonable diagnostic and treatment costs if a horse properly vaccinated by a veterinarian contracts the corresponding equine disease. Disease protection backed by the Equine Immunization Support Guarantee includes infection from West Nile virus, equine influenza virus, tetanus, Eastern equine encephalomyelitis virus, Western equine encephalomyelitis virus, and Venezuelan equine encephalomyelitis virus. Vaccinations must be provided and administered by a licensed veterinarian with an established client-patient relationship to be eligible. For more information on this program, horse owners should contact their veterinarian
