I think you need to check the results again. There were two studies run - with two different vaccines: one for 5 years, the other for 7. Both came out with VERY long-lived immunity. Titering is the key and need not be expensive as K State has just two years or so ago, come out with a cheaper, faster Rabies titer. I frankly have no fears in waiting several years between titers as that is what the science is showing. These animals have VERY long-lived immunity. 7 years DOI with one of the vaccines; 5 for the other. If one titers every three years, that's sufficient and perhaps not even necessary. Laws are being challenged as we speak and the data is VERY promising. Not sure what you saw that you thought the results were not promising, but according to the RC Study folks, the opposite is the case. (BTW, a study done in 2015 resulted in changes to the Compendium which virtually every state follows: study showed that dogs NOT UTD produced ANTIBODIES much FASTER and produced MORE of them than those dogs who were. So much for the scare tactics.....)
