Tetanus Vaccination
Tetanus is a serious life-threatening bacterial infection that can affect most mammals, including humans. Vaccination against tetanus is highly recommended for all horses in Australia.
Tetanus vaccines are typically administered annually and provide essential protection against this potentially fatal disease.
Strangles Vaccination
Strangles is a highly contagious respiratory infection that affects horses. Vaccination against strangles is recommended, especially for horses that come into contact with other horses frequently, such as those in boarding facilities or attending events.
Hendra Vaccination
Hendra virus is a highly contagious and potentially deadly virus that primarily affects horses and can be transmitted to humans. It is named after the suburb of Hendra in Brisbane, Australia, where the virus was first identified in 1994. Hendra virus is naturally carried by flying foxes (fruit bats) and can be transmitted to horses through their body fluids, such as saliva, urine, and birthing fluids.

Vaccination Protocols And Frequency
Vaccination protocols for tetanus, strangles, and Hendra may vary slightly depending on the region and veterinarian recommendations.
