"Brennen McKenzie, a veterinarian blogger and past president of the Evidence-Based Veterinary Medicine Association, says that he has seen an uptick in pet owners seeking to skip vaccinations for their pets against distemper and other ailments, such as parvovirus, a potentially lethal disease in dogs that can cause symptoms such as vomiting and lethargy. McKenzie says that he is also aware of cat owners who have become wary of vaccines. “I would say, from a subjective personal point of view, that often issues in veterinary medicine spill over from human medicine, and over the last 10 or 15 years there has been an increase in mostly unfounded concerns about vaccine safety for people — and that, I think, has raised people’s awareness and level of concern about vaccinations for their pets,” he explains." - rønin
