Common Vaccination Schedules For Your Horse

Scone Equine Hospital - Thursday, December 31, 2020
Common Vaccination Schedules For Your Horse

Vaccines are a ‘cheap insurance’ to protect your horses from more costly (and potentially deadly) diseases. Many equine vaccinations are standard and will be administered for all horses, although there are a range of vaccinations that will only be prescribed if there is a significant risk to the horse due to a possible outbreak.

It is recommended vaccination programs for your horse be tailored to the horse’s situation, the time of year, what they are going to do, where they are going to do it, and who they are going to meet. Performing a critical analysis of how you use your horse, how your horse travels, how your horse is managed and the environment in which your horse lives will all play a crucial role in determining a specific vaccination program for your horse(s).

When it comes to disease prevention, knowledge is key. Many horse related diseases can be vaccinated against and therefore save the horse’s life or prevent serious illnesses.

The tables below represents common vaccinations for common groups of horses within Australia. Owners should work in partnership with their veterinarians in determining which vaccinations are specific to each horse’s needs.
