My reactor gets the rabies vaccine, as it is a public health risk, but his long-time veterinarian told me the horse doesn’t need to get it every year, so it’s given every other.
Another veterinarian I used for several years told me that, when he was a vet student, he went with others to a prison that had one of those programs for the inmates to train horses. One horse was difficult for its exam, and inmates mentioned that this behavior was atypical for that horse.
Later, he and the other vet students got the call that this horse had been diagnosed with rabies, which explained the change in personality, and they all had to receive rabies boosters. He told me that they had already had an initial vaccination, as a condition of being a vet student.
In my area, my dog’s small animal veterinarian told me that there recently have been foxes in a nearby small town with rabies. We have foxes at our place, along with raccoons, skunks, etc., so rabies is not a vaccine I want to completely forgo. When I was a child and young adult, hundreds of miles away, nobody vaccinated for it, no vet recommended doing so, but it’s a different story here.
