Stampit, all 27 Vet Schools and the AAHA have endorsed a new vaccine protocol - if you haven't already seen this thread, it may be a good time to review this information and even print off a copy of the report to discuss with your vet ...http://www.thecatsite.com/forums/showthread.php?t=70742
Even though the top part of the report deals with puppies/dogs, you should still read/print it so you can give the information to your vet - you never know, it might help someone. The cat-related section is very informative and I have printed off a bunch of copies so I can distribute one to each of my kitten buyers as well.
I am not one of those old harpies when it comes to vaccines (at least not so much as I am with dry cat food - I HATE that stuff!!) but do believe we overvaccinate our animals, which actually compromises their immunity instead of helping.
I hope this helps both you and your vet to make informed decisions about your cat's needs for vaccines.
