Just for the sake of clarity, folks, no mammal is born with the least resistance to *rabies.* None. (Anyone remember Sabrina the Bat Biter?) None. There are no maternal antibodies to rabies that mammals recieve from their mothers UNLESS THE MOTHER WAS HERSELF VACCINATED AGAINST RABIES. And the protection that the offspring recieves from the mother against rabies fades very quickly, it does not last for life. This is true for a number of illnesses that companion animals are commonly vaccinated against. When you recieve a young animal with no history, you really need to sit down with your vet and discuss the matter. This site has a very nice, clearly written explanation of vaccination failures in general, as well as vaccination failure due to the lingering presence of maternal antibodies in the young offspring of vaccinated mothers. For that section in particular, please scroll down the page to reason number five, "Interference due to Maternal Antibodies." It explains why a vaccination series, rather than a single vaccination is often recommended for the young offspring of a vaccinated mother. http://www.sniksnak.com/doghealth/vac-failures.html Alexandra in MA [Posted in FML 5703]
