Rabies vaccination - feline
Q: Hello. I'm a physician (ENT) and a cat lover. Your site is outstanding. Would you kindly clear up a simple pair of questions for me?
1) What is the usual regimen of vaccination to initiate rabies immunity in a kitten? That is, one injection, or a series of 2 or 3?
2) As all rabies sera are killed virus, what significant differences exist between sera marketed as annual versus tri-annual? Thank you very much, Dean MD
Rabies vaccinations are all killed virus products at the present time. The standard protocol is to give one injection of the vaccine at 12 weeks of age or older and to repeat this in one year. Then the vaccine is repeated at one year or three year intervals depending on the state law and choice of vaccine. It has always been my opinion that the one year and three year vaccines were probably the same vaccines marketed differently. I have no proof of this and when I asked one of the vaccine company representatives he told me that there were differences in the adjuvents in some vaccines and rabies strain utilized for the vaccination in others. I have no reason to doubt this but I still can't see where there is probably a lot of difference. There is a significant difference in duration of immunity afforded by the use of differing strains of canine distemper virus, though. So maybe it is important.
It is highly likely that the protection afforded by rabies vaccination lasts much longer than three years but due to the severity of the disease and zoonotic potential most states are very cautious about taking chances and legislate one or three year vaccination intervals.
