Okay, I called the United Vaccines place (1-800-283-6465) and they were extremely friendly and helpful. They are the primary supplier of vaccines for mink farmers in the area and since mink and ferrets are so close in psysiology, you can use the same vaccines. The Fervac-D is (according to their representative) is the only vaccine so far which has been manufactured specifically for ferrets, and is (supposedly) the only vaccine currently licensed and which has USDA approval for use in ferrets. The Fervac-D comes in a 10-dose vial for $11.95. As Nancy stated, kits are supposed to be vaccinated at 8, 11 and 14 weeks and annual boosters after that. Adult ferrets with no history of vaccination (I would assume this includes ferrets with no history of *Fervac-D* vaccination, too) should have one dose with a booster three weeks later and annual boosters after that. I asked him if this vaccine was usable in dogs, since I'd heard that this new racoon-based distemper was affecting (or could affect?) dogs, too. He said that it was not licensed for use in dogs so he couldn't give me any statistics or recommendations for use in dogs. But a group of greyhound breeders has been using this vaccine in their dogs for an unspecified length of time (it didn't occur to me to ask how long) and they have had no ill-effects from it. I asked him if he knew just how much cross-over there was between Fromm-D and Fervac-D and he didn't know. (I was interested in knowing how similar the formulas were, if they protected for only one kind of vaccine, etc.) They will accept orders from individuals. They will send it COD or pre-paid with a credit card number. Shipping is $5. They send it UPS, and if it's hot, packed in ice in a styrofoam container. He said I should get it 2nd day (which didn't sound like the "2nd day" UPS shipping, but more like an endorsement of how quick the UPS is ... I'll let you know how quickly it gets to me if you're interested). I told him to include a catalog, so I may get more info soon. He said I should have the vaccine by the end of this week. I would be interested to know if others on the net (especially vet-types) would recommend giving this to my dog. It's certainly cheap enough. The dog was vaccinated at the vet's and I don't have the exact vaccines here with me. Is this affecting cats at all? --Barb-- [Posted in FML issue 0272]
