FAQ Answer #3
- For most horses we recommend these vaccinations:
West Nile Virus
Eastern Equine Encephalomyelitis
Western Equine Encephalomyelitis
Tetanus
Influenza
Rhinopnuemonitis
Potomac Horse Fever
These Vaccines are best given in the spring
(March -June) to offer the highest immunity during
the period of greatest risk of exposure to mosquito
born diseases.
The Flu / Rhino vaccination does not produce twelve month protection, so we recommend boosting
the Flu / Rhino component in the fall (September - December). This is also a good time to check your
horse's teeth.
In selected cases other vaccinations are indicated:
Rhinopnuemonitis (viral abortion)
Pregnant mares should receive this vaccine at 5, 7, & 9 months of gestation. Other horses on
a farm where pregnant mares may be present should at least receive the five way and Flu /
Rhino fall booster.
This vaccine is intranasal and usually only given to young horses. Strangles confers a lifetime
immunity, so if a horse has had strangles or been exposed or has had several doses of the
vaccine it is not necessary to continue giving this vaccination.
While this disease is rare in Southern Oregon, it does occur. (see news page) Also many of our
horses travel to areas where rabies is common; California, Texas etc. Keep in mind that rabies
in horses is always fatal and can be transmitted to owners and handlers.
