Question:
I've read that older pets should not have as many shots. My 16-year-old male alley cat visited the vet about six weeks ago for a bite wound. He had his usual exam, plus the yearly rabies shot but no other at that time because of the bite. He is now due for his three-year multiple-vaccine booster shot. I try to take him to the vet only once a year, unless there is a problem. I would like to know what is best for my cat, and don't understand exactly why certain shots are given. I know he needs to get the rabies shot every year because he's an inside-outside cat (he was an outside stray when he adopted us). He weighs about 11 pounds and is still fairly active, but he's slowing down some.

Answer:
Your letter is one of the reasons I keep writing this column, now going on more than 40 years. Veterinarians need to revise their vaccination protocols, profits notwithstanding. Repeated vaccinations could put an older cat at risk, and the cat should have good immunity because of all the earlier shots. No vaccination should be given to an already sick or injured animal. The rabies vaccination should not have been given during treatment for a bite wound. The other "core" vaccinations are good for three years so annual boosters are not advised. If in doubt, blood titer tests should be done to determine if revaccinations are needed. This is wise because no vaccine is without risk. For readers with computers, check my Web site for dog- and cat-vaccination protocols and a review of vaccination risks. Allowing a cat to go outdoors increases the risk of viral infection from other cats, so greater vigilance and judicious use of a broader spectrum of vaccinations is called for.
