WASHINGTON â?? Despite warnings that America’s dogs are being vaccinated too much and too often, most veterinarians continue the practice as a way to keep clients coming in the door, according to a leading animal immunologist.
Vaccines for rabies and three other major canine diseases â?? distemper, canine adenovirus-2 and canine parvovirus â?? should be given no more often than once every three years, said Ronald Schultz, a veterinary immunologist at the University of Wisconsin-Madison.
