West Nile-Innovator + EWT Horse Vaccine

West Nile-Innovator + EWT is a specialized veterinary pentavalent combination vaccine engineered to provide active immunization for horses and equines against West Nile Virus (WNV), Eastern and Western Encephalomyelitis (EEE/WEE), and Tetanus. By stimulating the animal’s immune system to produce protective circulating antibodies against these critical neurotropic and toxigenic pathogens, this professional-grade biological preparation delivers targeted, broad-spectrum disease prophylaxis for performance horses, breeding stock, and pleasure equines. Because immunological protection depends on precise primary vaccination series and timely booster administration, the use of this combination vaccine requires strict adherence to professional veterinary protocols.

What Is West Nile-Innovator + EWT?

West Nile-Innovator + EWT is a specialized veterinary biological compound formulated for parenteral administration under professional veterinary supervision.

Active Ingredients and Formulation

• Active Components: Contains inactivated West Nile Virus whole-virus antigen combined with inactivated Eastern and Western Encephalomyelitis viral fractions and purified Clostridium tetani toxoid, formulated with a safe adjuvant to maximize immune stimulation.

• Vehicle and Presentation: Supplied as a sterile liquid suspension in single-dose syringes or multi-dose glass vials designed for intramuscular administration.

What Is It Used For?

Primary Veterinary Indications

• West Nile Virus Prophylaxis: Routinely utilized by equine veterinarians and stable managers to prevent West Nile Virus neuroinvasive disease transmitted by infected mosquitoes.

• Encephalomyelitis Protection: Guards equines against the debilitating and frequently fatal neurological damage caused by Eastern and Western Encephalomyelitis viruses.

• Tetanus Prevention: Protects against fatal neurotoxin poisoning resulting from Clostridium tetani entering puncture wounds, lacerations, or surgical sites.

Administration and Dosage Considerations

Route and Dosing

• Route of Administration: Administered exclusively via intramuscular (I.M.) injection—typically into the deep muscles of the neck—utilizing strict aseptic technique and sterile needles.

• Primary Vaccination Series: Requires a series of two initial doses administered at intervals of 3 to 4 weeks for primary immunization in un-vaccinated horses, followed by annual boosters (or semi-annual boosters in high-vector geographic regions).

• Veterinary Guidance: Consult your attending veterinarian to establish an optimized vaccination schedule tailored to regional disease pressures, mosquito activity seasons, and individual stable management practices.

Important Safety Information

• Contraindications: Do not vaccinate animals showing signs of acute febrile illness, severe stress, or those with a known history of hypersensitivity reactions to previous vaccinations or vaccine adjuvants.

• Side Effects and Precautions: Mild transient lethargy, decreased appetite, localized swelling, or slight soreness at the injection site can occasionally occur within 24 to 48 hours following injection. Systemic allergic reactions (anaphylaxis) are rare but require immediate veterinary intervention (epinephrine and supportive care).

• Competition Regulations: Trainers and exhibitors should schedule vaccinations at least 7 to 14 days prior to competitions or shipping to allow full immune response development and resolve any temporary post-vaccination fatigue or stiffness.

• Professional Guidance: Biological products must be handled and administered under the direct oversight of a licensed animal health professional.

Storage and Handling

• Store refrigerated at temperatures between 2°C and 8°C (35°F to 46°F). Do not freeze. Freezing destroys the adjuvant structure and ruins vaccine efficacy.

• Protect from direct sunlight and excessive heat during transport and storage.

• Agitate well immediately prior to drawing up or administering the dose.

• Keep securely out of reach of children, unauthorized individuals, and animals at all times.
