Hi all I just wanted to correct a previous post. No, I did not recommend or mention Neovac D vaccine. I recommend Merial's Purevax distemper vaccine. Neovac D is a modified live distemper vaccine that is not USDA approved for use in ferrets. The company did a very small study in ferrets, and there were no adverse effects. However no study has been done to see if Neovac D actually protects ferrets from distemper. Hope that clears up the confusion, Jerry Murray, DVM [Posted in FML 7068]
