Initial Vaccination Series:
* Foals: First vaccination at 4-6 months of age, followed by a booster 4-6 weeks later.
* Adult Horses: Two initial vaccinations spaced 4-6 weeks apart.
Booster Schedule:
* Annual Boosters: Horses with high risk of exposure (e.g., those regularly competing or living in environments with a high incidence of tetanus) should receive annual booster vaccinations.
* Every 2-3 Years: Horses with moderate risk of exposure can receive boosters every 2-3 years.
* Every 5 Years: Horses with low risk of exposure can receive boosters every 5 years.
Factors Affecting Vaccination Frequency:
* Age: Foals and older horses may have weakened immune responses and require more frequent vaccinations.
* Exposure Risk: Horses with higher exposure to tetanus bacteria (e.g., those living in dusty environments or receiving wounds) need more frequent boosters.
* Vaccination History: A horse's previous vaccination history can affect the frequency of booster shots.
Consult Your Veterinarian:
It's crucial to consult your veterinarian to determine the appropriate vaccination schedule for your horse. They will consider your horse's individual needs and risk factors to ensure they receive adequate protection against tetanus.
Remember: Even with proper vaccination, prompt wound care and tetanus antitoxin administration are crucial in the event of a wound.
