Vaccinations & Deworming


Routine vaccinations should be considered as a part of every horse’s health care regimen. Obviously, depending on your horse’s age and lifestyle, the vaccinations he or she needs will be quite different. At Agrifarm Health Centre we are keen to develop a vaccination protocol perfectly suited to each horse.

Here are some basic guidelines:

  1. Foals

If a mare has been properly vaccinated prior to foaling, your foal should be protected by maternal immunity until the age of approximately 5 months. At this time, a vaccination protocol should be developed according to his or her needs. Tetanus and rabies are essential, and tetanus booster must follow the initial inoculation 3 – 4 weeks later. Other considerations include West Nile virus, Eastern and Western encephalomyelitis, influenza/rhinovirus, and Strangles.

  1. Non Pregnant Adult horses:

Vaccination against diseases contracted from mosquitoes are recommended between March and June every year

  • Eastern Equine Encephalitis
  • Western Equine Encephalitis
  • West Nile Virus
  • Tetanus is contracted from the soil and is recommended once a year
  • Rabies is contracted from other animals and is recommended once a year

                Recommendations for non-pregnant horses exposed to other horses:

  • Intranasal Strangles vaccination is recommended once a year
  • Influenza and Herpes vaccination is recommended twice a year (spring and fall)


These are recommendations only. Please contact us to discuss your horse’s individual needs.

Equine parasites are developing resistance to our deworming medications. This is why we recommend a scientifically-based approach to deworming you horse(s), based on fecal egg counts. This test tells us how to treat strategically to decrease the amount of resistant worms evolving within your horse/herd and the general population.

               Recommendations for non-pregnant, adult horses:

  • Spring
    • Fecal Egg Count
  • Late Summer
  • Fecal Egg Count
  • Autumn when outside temperature is consistently below 0 C
  • Deworm
