Vaccination Programs
The goal of Colts Head Veterinary Services’ vaccination program is to prevent costly, life-threatening diseases using vaccines based on the individual horse’s risk of exposure to disease. We follow the American Association of Equine Practitioners (AAEP) guidelines on core vaccines versus optional vaccines. Spring vaccines are performed between April 1 and June 1 to ensure optimal protection against mosquito borne diseases. Generally, it is best to divide spring vaccines over two visits.

Based on these guidelines we recommend the following vaccine programs:


Horses that live on a small farm, never leave the farm, are never exposed to outside horses, and none of the other horses on the farm are exposed to outside horses

Spring Fall

West Nile
Tetanus

Horses that live on a small farm, are occasionally exposed to other horses at small gatherings (for example, group trail rides but not horse shows or large clinics), and no other horses on the farm travel to horse shows or large clinics
