Equine Vaccination Recommendations

It’s Spring, Time for Vaccinations!

A “standard” vaccination program for all horses does not exist. Each individual situation requires an evaluation. Ask your farm vet what is best for your horse.

In Arizona, we have the risk of several infectious diseases, which can be vaccinate for. These vaccinations are different based on the age, condition and exposure of the horse.

In Phoenix, March is the best time to give spring shots.  Here at the ranch, I vaccinate for Eastern & Western Encephalomyelitis, Tetanus Toxoid,  Influenza, and West Nile.

A General Guide for the Adult Horse

Tetanus Toxoid, Eastern & Western Encephalomyelitis: Spring, Annual

Influenza & Rhinovirus: Bi-Annual/Spring & Fall

West Nile: Bi-Annual/Spring & Fall

Strangles:  Bi-Annual/Spring & Fall

Rabies: Optional


Anticipated exposure, environmental factors, geographic factors, age, breed, use, and sex of the horse affect the risks of disease.

The primary series of vaccines and booster doses should be appropriately administered prior to likely exposure.

Each horse in a population is not protected to an equal degree, or for an equal duration, following vaccination.

 Protection is not immediately afforded the patient after administration of a vaccine that is designed to induce active immunity. In most instances, a priming series of multiple doses of a vaccine must be administered initially for that vaccine to induce protective active immunity.

All horses in a herd should be vaccinated at intervals based on the professional opinion of the attending veterinarian

A properly administered, licensed product should not be assumed to provide complete protection during any given field epidemic.
