The best immunization program for your horse varies widely according to a horse’s age, use, and environmental factors.
We have developed the following guidelines considering many of these factors, but we recommend checking regularly with us regarding changes due to such things as new research or area outbreaks of disease.
“EWT” – Intramuscular Eastern&Western Encephalitis and Tetanus vaccine
“PHF” – Intramuscular Potomac Horse Fever vaccine
“FLU” – Intramuscular Influenza vaccine
“FLU AVERT” – Intranasal Influenza vaccine
“IN STRANGLES” – Intranasal Strangles vaccine**
“EHV 1&4” – Intramuscular Rhinopneumonitis vaccine
“EHV 1” – Intramuscular Viral abortion vaccine for broodmares
“IM STRANGLES” – Intramuscular Strangles vaccine
“FLU/RHINO” – Intramuscular Influenza and Rhinopneumonitis vaccine
“WEST NILE” – Intramuscular West Nile Virus vaccine
“RABIES” – Intramuscular Rabies vaccine.
“4-way” – A combination vaccine of EWT and one other disease.*
“5-way” – A combination vaccine of EWT and two other diseases. *
*Note: combination vaccines are associated with a higher incidence of vaccine reactions.
** Intranasal Strangles Vaccine is not recommended for horses older than 5 years except in high-risk
situations. Horses that have had the actual disease should not be vaccinated for Strangles.
The above schedule may be modified if your foals are raised in a closed herd without contact with other horses. Your veterinarian is the best resource to help you design a vaccination protocol that fits your situation, and the needs of your horses. Research has shown that foals are much better protected by a series of three injections of a vaccine than they are by two. Also note that influenza vaccines should not be given to foals less than 9 months of age, due to interference by antibodies that the foal acquires from themare through the colostrum.
Broodmares that are not in foal should be vaccinated as below for an adult pleasure horse. West Nile vaccination should be discussed with your veterinarian. We recommend vaccinating for West Nile 4-6 weeks before the expected foaling date along with the other vaccines given at that time to boost the immunity transferred to the foal through the colostrum.
Adult Retired / Inactive Horse Vaccinations
Spring (March-April) – EWT-WEST NILE, PHF, FLU/RHINO, AND RABIES
* Horses younger than 5 years old should also be given IN Strangles.
Pleasure Horse Vaccinations
Competition Horse Vaccinations
Rabies: Historically, rabies has not been diagnosed in the equine population of Oregon. Recent increases in the number of rabid bats (common residents of barns) have prompted us to include rabies in our recommended list of vaccinations. If your horse will be traveling outside the state, vaccination for rabies is strongly recommended.
In certain cases it may be advisable to vaccinate horses with one or more of the following vaccines, discuss your situation with your veterinarian:
Equine Protozoal Myelitis, Equine Viral Arteritis, Botulism, Rotavirus and Venezuelan
