In the recent newsletter of the Baltimore Ferret Club (Nov. 28, 1994) there was a reprinted letter from Dr. Susan A. Brown, DVM. In this letter she says that Solvay has stopped producing the distemper vaccine Fromm-D and has replaced it with Galaxy D, which uses simian (monkey) rather than avian (chick embryo) cell cultures. She says: "No one knows the significance for the ferret of this change. It may not be a problem at all, but until it is tested, we are recommending not to use it. The veterinarian I spoke to was clear that the vaccine HAS NOT been tested in any exotics since it was tested in and designed primarily for dogs so they CANNOT recommend it for ferrets at this time." I think this means that we will stop vaccinating our older two ferrets Ben and Jerry against distemper. They had a severe reaction to FervacD last May. I think that further FervacD vaccinations would probably kill them. Does anyone have any more information about this? I know that Dr. Brown is on the FML but don't recall seeing postings from her recently. Dr. Brown, are you still there?
