I think you can have something called a Tiller test to see if the vaccines are still active in there system( trouble is this cost about the same amount of the vaccine) that way you are not over vaccanating( I know I spelled that wrong) I'm going to copy and paste some things From Dr. Hodgkins’
From Dr. Hodgkins’ Pearls Gleaned:
DO NOT vaccinate your indoor kitties or those that go outside under supervision for FELV. FELV is transmitted from an infected cat to an uninfected cat after very close and long-term contact. It is not airborne or transmitted via feces or urine. It is transmitted mostly through an exchange of a great deal of saliva. FELV vaccine, along with the 3 year rabies vaccine, is most implicated in vaccine associate fibrosarcoma.
FIP vaccine is a complete and utter waste of time and I must say that any vet that uses this routinely on their patients isn't even thinking. I mean it, if your vet asks to vaccinate your cat for FIP you must ask why. If he/she isn't able to give anything more than "that's what we do" you might want to change vets. I know many of you have vets you like and trust, and that is a good thing, I mean it. But even the American Association of Vet Practitioners and other "authorities" do not recommend this vaccine. It has a very poor testing history for even preventing FIP and is nothing more than another shot to give and charge for in vet practice. It has value in my eyes only for identifying doctors who don't care enough about patients to even examine vaccine protocols to make sure they are sane.
Rabies is tougher. I happily live in a county where rabies vaccination is not required, and I do not vaccinate my patients for rabies at al l(I only use the 1 year when I have to give it, as when a cat is going to travel internationally). I board at my clinic so my clients don't have a problem boarding their cats with no rabies vaccinations. I know Texas and a few other places are thornier about this, but never let your cat have the 3 year vaccine. This does not mean your cat needs to be given the 1 year every year, unless some authority is forcing the issue. The duration of immunity for virtually all vaccines that work at all is much longer than a year, so if your cat gets out and tangles with a skunk, or bites someone, and has had the 1 year within the last few years, it is not going to get, or give, rabies. The 1 year vaccine has that rating because the manufacturer only tested it for 9- 12 months and then stopped testing. Why would they test longer? It costs money to conduct long-term tests and long term tests will just reduce sales. It is lose-lose for them, right?
Anyway, there are reasons to avoid vaccination as much as possible beyond sarcomas. Other, probably more common, health problems come from over-vaccination. The cat's immune system is very reactive, and annual vaccines can trigger autoimmune diseases of many kinds. I would not give FRVCP more than every 3 years and do not give even this in cats that are 6 years or more in age. We do not see the diseases this vaccine protects against in adult indoor cats, but we sure do see the side effects.
As far as the annual vet visit, I think it makes sense to see the vet once a year (there is currently a campaign to recommend wellness exams every 6 months with which I do not agree) especially to examine the oral cavity and, in older cats, to make sure there is nothing else afoot that is not causing signs that the owner notices. During such exams, I weigh the patient (this is the cheapest, least invasive, and most important "diagnostic test" in the world and will show early onset of many diseases). Few owners have scales sensitive enough to disclose low-grade gradual weight loss and I have diagnosed so many early hyperthyroidism cases this way, I can't even tell you. I pick up most of my hyperthyroid patients while their thyroid hormone levels are still in the so-called "normal" range, while the prognosis for cure is still excellent.
Each cat has a different need for routine vaccines and exams. If your vet isn't applying a risk-benefit kind of evaluation to YOUR cat, but instead is just doing the same thing, every year, for every cat, you MUST ask why. This is NOT appropriate medicine today, and every owner and every cat deserves better.
The recommendation that cats receive vaccinations at frequent intervals throughout life totally ignores basics of immunity, not surprising when you consider that government, which oversees human health issues like vaccine reactions and the risk/benefit analysis for vaccination in humans, doesn't give a wit for pet health per se. Pets, like people, derive quite solid immunity from the vaccinations that actually work, like the FRVCP, from the first few vaccine administrations, and revaccinating at frequent intervals in later life may actually reduce the effective immunity in the animal with this pre-existing protection. Now, this is a well understood phenomenon in biological systems and is the basis for not vaccinating humans on an annual basis for anything (when was the last time you received any kind of vaccine?...I haven't gotten anything for decades and even my 19 year old son hasn't received any kind of vaccine for years).
The reason we vaccinate pets every year for EVERYTHING has nothing to do with health imperatives, it has to do with the fact that vaccine manufacturers want it, vets have stopped thinking about the science of these protocols and just do it, and the government couldn't care less if pets die as a result. Federal and state governments figure they have bigger fish to fry than whether a few thousand cats die of vaccine reactions. And none of the involved industries are self-regulating. Sad but true.
The reason those of us who have actually thought about rational rabies vaccination recommend only the 1 year vaccine is because it does not have adjuvants. Adjuvants cause a hyper reaction to the vaccine, thus allowing the longer duration of immunity claims. But, adjuvants are strongly implicated in vaccine reactions, and not worth the risk. As I said in the earlier post, however, just because a vaccine only has a 1 year manufacturer's test behind it does NOT mean it lasts only that long.
