A discussion of vaccine alternatives: >Assuming that Galaxy-D is actually effective in ferrets - it probably is >despite not having been tested per se. While it was not tested by the manufacturers, Elizabeth Williams, a wildlife vet in Wyoming who works extensively with the black footed ferrets had the opportunity to try in in comparison to an subunit vaccine (that is produced by Merial, and currently used in many zoos to vaccinate exotic animals against distemper.) I will post the abstract below. For information purposes, the MLV vaccine in the abstract was Galaxy. This is not to say, however, that Galaxy is totally safe in ferrets - there are reactions (although less than with Fervac-D, and probably equivalent or thereabouts to those seen with the Imrab rabies product.) The Galaxy vaccine gave very sufficient titers to the animals in this study, with no side effects. With kindest regards, Bruce H.

Williams ES, Anderson SL, Cavender J, Lynn C, List K, Hearn C, Appel MJ Department of Veterinary Sciences, University of Wyoming, Laramie 82070, USA. An inactivated canine distemper vaccine with adjuvant and a modified-live virus (MLV) vaccine were evaluated using black-footed ferret (Mustegla nigripes) x Siberian polecat (Mustela eversmanni) hybrids us surrogates for endangered black-footed ferrets. For comparative purposes, we also vaccinated domestic ferrets (Mustela putorius furo) with the MLV vaccine. Response to vaccination was measured by clinical observation, hematology, dynamics of serum virus neutralizing antibodies, and challenge with virulent canine distemper virus. No clinical signs attributable to the vaccines were observed. Transient leukopenia occurred in hybrid ferrets that received MLV vaccine and there was marked lymphopenia for approximately 52 days post-vaccination. Lymphopenia was present for approximately 21 days in domestic ferrets vaccinated with MLV vaccine. Neutralizing antibodies against canine distemper virus were detected 14 days post- vaccination in hybrids receiving MLV vaccine and most titers were > 1:1024 for the 791 days of the study. Antibody titers in hybrids vaccinated with the inactivated vaccine were significantly lower. All eight hybrid ferrets that received MLV vaccine survived challenge with virulent canine distemper virus without clinical disease. However, one of seven hybrids vaccinated with the inactivated vaccine developed canine distemper and was euthanized; two other hybrids became clinically ill but survived. The MLV vaccine may be useful in prevention of canine distemper in black-footed ferrets, but until additional studies of efficacy and safety are completed, use of the inactivated vaccine is appropriate.
