I've been sitting on this question for a while. While I was camping over the fourth my vet tech friend was telling some of the people with us that they shouldn't vaccinate their dogs any more. They had older dogs. She explained that once they get that certain amount of vaccine (just like people 1 vaccine and 1 booster) they are vaccinated for life. That after that it is really just vets trying to make money rather than keep your pets safe. She was also saying that there was a study done (on dogs I believe) that after a certain age it was dangerous to give them vaccinations because it did something to their immune system. Is this true? Are we continuing to vaccinate only to protect our fuzzies from ignorant people? Is this true with ferrets that after a certain age vaccines actually impair the immune system? I guess that's more than one question. I don't really know whether to believe her or not. But I do know that she has been trained and I haven't. I think this list is an excellent resource because of the knowledge contained here (thanks BIG) so lets pool these smarts together and see what we come up with on this one.
