I too, try to avoid vaccinations, but have found it necessary to return to vaccinating when I moved to a more remote area abundant with wildlife and the ferals started moving in.
We had a distemper (panleukopenia) epidemic here last summer, it was awful. I really hate burying kittens. There have been confirmed cases of rabies in the area (raccoon and coyote, both of which frequent the property)and the ferals brought the Cali-virus (sp?) along.
While I agree that vaccination probably is not necessary in MOST household situations, there are some situations that warrant it. I care for a large population of cats (we are in the middle of a neuter-a-thon) and there is wildlife present. Even our holistic vet says vaccination is warranted in my situation, although he has me "detox" with homeopathic nosodes specific to the vaccines afterwards. I have also adopted a modified schedule -- only the "core" vaccines, the first given at 6 months of age and a booster a year later, then no more (much to the allopathic vet's dismay) and rabies no more than every three years as required by PA law. And my 17 year old lady cat has not received any vaccines since age 10 years and she will receive no more, I figure she has lifetime immunity now.
