Fluvac Innovator®

Fluvac Innovator EHV-4/1 provides your horse with trusted protection against equine influenza and equine herpesvirus,1 and is the perfect pair to Core EQ Innovator.

The importance of protecting against respiratory disease

Respiratory diseases such as equine influenza (flu) and equine herpesvirus (rhino) are classified as risk-based by the American Association of Equine Practitioners (AAEP) because their likelihood of occurrence depends on factors like travel or cohabitation with traveling horses.2 Due to their high contagiousness, flu and rhino are the top risk-based vaccinations recommended for horses. Among risk-based diseases, respiratory disease is the primary cause of horse death, with equine flu and herpesvirus being the main respiratory illnesses.2

    Horses at increased risk of exposure may receive booster every 6 months
    Annual revaccination and administer 4-6 weeks pre-partum

    Broodmares with ongoing risk of exposure should be boostered every 6 months
     
    In addition, other risk-based diseases may also pose a threat to your horse based on his unique needs and circumstances. Your veterinarian can provide guidance on which additional vaccines from the Zoetis portfolio may be appropriate for your horse’s vaccination schedule. See the vaccination guides below for adult horses, broodmares and foals for recommendations on what Zoetis vaccines may be appropriate for your horse’s unique needs.

    What sets Zoetis Innovator vaccines apart?

    MetaStim® adjuvant

    Only Zoetis Innovator vaccines are optimized with the MetaStim® adjuvant, designed to make presenting antigens into your horse’s immune system safe and effective, leading to an improved immune response.13,14

    Microfiltered 5x

    Zoetis Innovator vaccines are microfiltered five times to remove excess proteins that could lead to increased reactivity, resulting in greater antigen purity.

    Zoetis Vaccine Support Program

    When you protect your horse with Core EQ Innovator and Fluvac Innovator EHV-4/1 vaccines, you are also protected with one of the industry’s best Equine Immunization Support Guarantees. This reimburses up to $5,000 for documented diagnostic and treatment costs if a veterinarian properly administers one of these vaccines and the horse later contracts the corresponding disease. For complete details and requirements, see the see the Zoetis Equine Immunization Support Guarantee certificate.
