What vaccinations are compulsory when entering a horse in competitions?

Answer 1

The type of vaccines that are compulsory when entering a horse in competition may vary from event to event so it's advisable to check the requirements with the organizers of each specific event.

I have never heard of horse events requiring vaccines to be given to horses entered in them. The only related item that most competitions require is a current (within the last year) negative coggins test. A coggins test checks for the presence of Equine Infectious Anemia which is a highly contagious disease in horses. A coggins test is not a vaccine, only a test for the disease. There is no cure for the disease and horses that test positive for EIA must be euthanized or kept quarantined from other horses for the rest of their lives.
