I'd like to thank the poster of this question for reminding to ask my own version. First, it is highly recommended that the C.D. and rabies vaccinations are separated by two weeks time. As to the sequence for the CD boosters, I don't know, and therein lies my question as well. We recently took in a young (maybe 6 mos old) ferret that was found in a heavily wooded trailer park. He's had his rabies shot as well as a CD shot. *MY* understanding based on what I've read in United Vaccines' ads is that the spaced boosters are intended to supplement the natural immune system the kits inherited from their mom. This temporary immunity can block the initial vaccines for up to about 14 weeks, therefor the vaccines 'boosters' are given. Is there any reason to give more than a single shot to a ferret that is obviously older than 4 mos (about 16 weeks)? -Erin... ========================= Mr. Erin M.
