Hi, I'm really sorry to bring this up again, but I'm still frustrated and confused, despite all your helpful answers. It's about ferrets with unclear vaccination histories. I've been asking what to do - one shot or a series - for ferrets that may not have had the original series of shots, but have had annual vaccinations, one, two or three years' worth of a single vaccination. The answer I keep getting is unclear: If your ferret has never had a vaccination or you don't have ANY knowlege of the vac. history, get them the series. But what if you know the history? I have two ferrets, each about two years old, who got one distemper shot at about one-years-old and one this month. I didn't know about the required series when I got them, so didn't ask the previous owner if they'd had them. I could go ahead and get them the booster in a couple weeks, but would prefer to use the money elsewhere if they don't need it. My two little youngsters and a two-year-old I know nothing about will get the boosters for sure. My two guys from the university research program I hope to get histories for, or I'll get the boosters. Nobody had a reaction to the first series - Yay!!! They'll all get the rabies in a month or so, depending on who gets the booster. I'm do glad you're all here!! Aren't ferrets grand???!!!!! Lynn Mc. [Posted in FML issue 1356]
