Frequently Asked Questions

Q1: What does Prestige 3 + WNV Equine Vaccine protect against?

Ans: Prestige 3 + WNV Equine Vaccine helps protect healthy horses 6 months and older against Eastern and Western equine encephalomyelitis, tetanus, and West Nile Virus. The vaccine supports core immunization planning for diseases commonly included in annual equine vaccination programs.

Q2: What is the dosing schedule for Prestige 3 + WNV Equine Vaccine?

Ans: The primary series is 1 mL given intramuscularly, followed by a second 1 mL intramuscular dose in 3-4 weeks. After the initial series, revaccination timing should follow veterinary guidance and risk-based exposure planning.

Q3: When should horses receive West Nile vaccination during mosquito season?

Ans: West Nile protection is typically planned for peak mosquito activity, since immunity is stronger after completing the two-dose initial series. A veterinarian can recommend booster timing based on geographic risk, travel, and seasonal mosquito pressure.

Q4: Can foals receive this vaccine on the same schedule as adult horses?

Ans: Foals can have maternal antibodies that interfere with the development of active immunity. The label guidance notes that additional boosters may be required in most young animals. A veterinarian should determine the timing based on the foal's age, the dam's status, and the exposure risk.

Q5: Does the vaccine prevent disease or reduce the severity of West Nile Virus?

Ans: The indication supports vaccination against West Nile Virus as part of a preventive program. Protection depends on completing the recommended series and matching boosters to risk. Management practices that reduce mosquito exposure remain important alongside vaccination.

Q6: What side effects can occur after vaccination?

Ans: Local reactions such as swelling or soreness at the injection site can occur and commonly resolve within 3-7 days. Systemic reactions may occur as well. Rare allergic reactions are possible and should be addressed promptly with veterinary support.

Q7: How should Prestige 3 + WNV Equine Vaccine be stored and handled?

Ans: Store the vaccine refrigerated at 2°-8°C and shake well before use. Use the entire contents when first opened and do not mix with other products. Follow aseptic technique and administer by deep intramuscular injection only.

Q8: Can the vaccine be used during an outbreak or high-exposure conditions?

Ans: Label guidance indicates early revaccination may be advisable when horses are faced with an outbreak or conditions that make heavy exposure likely. A veterinarian should assess the situation and recommend whether additional boosters are appropriate.

Q9: Are there any key precautions for breeding horses or pregnant mares?

Ans:  Vaccine labels commonly note limited testing in pregnant animals for certain products, so a veterinarian should guide breeding decisions. A risk-benefit assessment should consider disease pressure, travel history, farm history, and timing within a broader vaccination schedule.
