I'm sure it varies vaccine to vaccine. Regardless... I wont vaccinate except for one time (except rabies, where I have some legal consequences involved if I don't). That being said, I quarantine any new cats that come in, just in case. The thing is, some of the things we vaccinate for are not typically fatal illnesses for healthy adult cats anyways, so it's kinda like getting the flu shot if you're a human, yes, it will keep you from getting sock, but unless you're old, ill, or weak in some way, it generally wont kill you even if you DO get it. I don't get flu shots for myself either, for the record... and when I went to college, I refused my hepatitis and whatever else they give you at that age (some childhood vaccine booster), and got a titer pulled on myself, and it proved sufficient immunity to allow myself to be admitted.
