The following is a general vaccine protocol that we recommend to all clients. Each individual situation is different and therefore some horses may be at a higher risk for certain diseases than other horses. Please speak with us if you have any questions regarding this vaccine protocol or your horse’s individual risk.


  • Potomac Horse Fever
    (ideal time: May and August)
  • Equine Flu
  • EHV “Rhino”


  • West Nile Virus
  • Strangles (streptococcus equi)
    for at-risk horses
  • Rabies
  • TTEW (tetanus toxoid, East/West Encephalomyelitis)
  • Botulism (ideal time: May and August)

Pregnant Mares

Rhino (EHV I/IV killed) 5,7,9 and optionally 3 months of gestation.
Booster at ten months of gestation: TTEW, Rabies, Potomac Horse Fever, Botulism, West Nile and optionally rotavirus at 8,9 and 10 months of gestation.

Pregnant mares need to be vaccinated against Equine Herpes Virus I/IV at 5,7,9 months of gestation and optionally at three months. This vaccination protocol is designed to minimize the risk of abortion due to this virus. These mares should also have nearly all of their vaccines boostered at 10 months of gestation to ensure that the mare has high colostral antibodies at parturition. This will help the foal get needed immunity from its mother for the first few months of life.


As a general rule we recommend that you vaccinate foals from unvaccinated mares (not boostered at ten months of gestation) at three to four months of age. This will include TTEW, Rabies, Botulism, Potomac Horse fever and West Nile Virus. We recommend waiting to vaccinate for Strangles and Flu until six months of age in these foals. For foals born to vaccinated mares we recommend that all vaccines be started at six months of age. Nearly all of these vaccines require 2-3 boosters.
