Prestige 5 + WNV Horse Vaccine

Prestige 5 + WNV is a specialized veterinary pentavalent viral combination vaccine enhanced with West Nile Virus protection, engineered to provide active immunization for horses and equines against Eastern and Western Encephalomyelitis, Tetanus, Influenza, Rhino-pneumonitis (EHV-1 and EHV-4), and West Nile Virus. By stimulating the animal’s immune system to produce protective circulating antibodies against these critical infectious agents, this professional-grade biological preparation delivers comprehensive, 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 Prestige 5 + WNV requires strict adherence to professional veterinary protocols.

What Is Prestige 5 + WNV Vaccine?

Prestige 5 + WNV is a specialized veterinary biological compound formulated for parenteral administration under professional veterinary supervision.

Active Ingredients and Formulation

• Active Components: Contains chemically inactivated viral fractions and purified toxoids covering Eastern Encephalomyelitis Virus (EEE), Western Encephalomyelitis Virus (WEE), Tetanus Toxoid (Clostridium tetani), Equine Influenza Virus (Strains Ky/93 and Ky/99 respiratory protection), Equine Herpesvirus Types 1 and 4 (EHV-1, EHV-4), and West Nile Virus (WNV), combined with a safe adjuvant to stimulate robust immunity.

• 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

• Encephalomyelitis Prophylaxis: Routinely utilized by equine veterinarians and stable managers to protect horses against mosquito-borne Eastern and Western Encephalomyelitis viruses causing severe neurological disease.

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

• Respiratory Disease Control: Mitigates clinical signs and viral shedding associated with Equine Influenza and Equine Herpesvirus (Rhinopneumonitis, including abortion risk mitigation in broodmares).

• West Nile Virus Protection: Defends equines against West Nile Virus neuroinvasive disease transmitted by infected mosquitoes.

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 for high-risk influenza exposure).

• Veterinary Guidance: Consult your attending veterinarian to establish an optimized vaccination schedule tailored to regional disease pressures, seasonal exposure risks, 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.

Directions:

For primary vaccination, administer 1 mL intramuscularly and repeat with a single dose in 3 to 4 weeks. Annual boosters are recommended, and for foals, additional boosters may be necessary due to maternal antibody interference. Always consult your veterinarian for specific revaccination schedules.

Cautions and Warnings:

Store between 2°C and 8°C (35°F – 46°F). Shake well before use. Use the entire contents once opened. Do not mix with other products. Has not been tested in pregnant animals. Do not vaccinate within 21 days prior to slaughter. Inject deeply into the muscle only. Local reactions at the injection site may occur and typically resolve within 3 to 7 days. Systemic reactions may also occur. In case of allergic reaction, treat with epinephrine. Avoid accidental injection into your fingers, hands, or other body parts. In case of human exposure, contact a physician immediately.
