>>Due to sarcomas (site cancers) appearing in cats who were given the three year rabies vaccine, the FDA has suggested that cats get a rabies vaccine every year (which actually can be found as a still active titer at 18 months after the vaccine was last given).
Well, no. The FDA has absolutely nothing to do with animal vaccines. The USDA oversees animal vaccines. And the USDA has issued absolutely no recommendations relating to feline injection site sarcomas and rabies vaccination.
The only people "suggesting" annual rabies vaccination are the makers of Purevax, an adjuvant-free rabies vaccine for cats made by Merial, which may or may not reduce the incidence of sarcomas. I don't know, they don't know, and no one knows yet if that's true. Time will tell. And Merial is still testing Purevax for a three year label claim. To suggest that cats get a rabies vaccine annually to prevent injection site sarcomas is very dangerous advice if the vaccine is the standard rabies vaccine with adjuvants, and even if it IS Purevax, we still do not really know that will be safer. Injection site sarcomas have been caused by insulin injections, needle sticks for blood draws, and other forms of puncture, not just by rabies or other vaccines with adjuvants.
> As you probably know, rabies is required even for indoor-only cats because mice, squirrels, bats, etc. can get into your home and can be carriers. <
This is not true ... it varies from state to state. The state where I live, California, does not require rabies vaccination for cats. I don't argue whether or not it's ADVISABLE, I'm simply saying it's not required.
> (Titers have been described to me as the indicators of the active immunity in the blood.) <
While having a titer (a measurable level of antibodies) in your blood does indicate immunity, NOT having a titer does not indicate lack of immunity. That's because immunity comes from memory cells, which we can't measure. Memory cells produce antibodies, but we don't need antibodies in our blood to make us immune.
>>The feline leukemia vaccine (which is only really needed if your cat will be exposed to other cats in an outdoor environment) can last up to three years > but a lot of vets are reccommending that it also be given every year because it's less effective (only about 85% in cats on the three year plan), so more frequent vaccines for kitties who go outdoors helps boost their immunity by refreshing the titers more frequently. >The distemper vaccine (which a lot of vets are calling a "3-way" because it protects against 3 airborne viruses - and has NOTHING to do with your cat's temper) has been approved as an every three year vaccine. It seems to be the only one that maintains a full three year titer without causing sarcomas or other negitive reactions at the injection site. >There are, of course, several vets who will do the three year rabies, leukemia and distemper vaccines on alternating schedules (so that they see your cat every year, but only give one vaccine per year.) >> >>This is information I was given by a cat only vet.
And yet there is no more scientific evidence in support of a three-year interval than there was for the one-year interval. ----- Christie Keith Caber Feidh Scottish Deerhounds Holistic Husbandry since 1986 Meet the Felines!
