Hmmm. I think I am divided on this issue. Where I live, I am pretty sure there are things that are really common besides heartworm (which, as we all know, is not taken care of by vaccination but rather a topical or pill.). I would just be worried about my fur babies coming in contact with any diseases. Hmm. I shall do some more research.

So far, (even though this doesn't apply, exactly) Soni has been vaccinated against rabies, feline leukemia, and fvrcpc. I will do the same for Isis because not only is it required by law but I have to do it in order for her to be spayed (some even require a bordatella vacc.).

edit: As far as human vaccinations go, I have had a polio vaccination, and have started the hep b several times but never finished, amongst others and have never had a problem with them myself. Then again, I've always been pretty darn healthy minus the ear infections when I was way younger and especially concerning something else.
