To Rita,
 
After 6 years of reaction-free distemper vaccinations, I would be
inclined to go back to the "wrong" vaccine.
 
Here in Perth, Western Australia, thousands of ferrets over the last 9
years have been receiving dog vaccine with not one reaction.  In fact a
distemper-only vaccine is not available in this country, so the ferrets
also get immunised against hepatitis and parvo.  No reactions, no
distemper....ever.
 
I would be very interested to know if there were any reactions to
distemper vaccines before the ferret-specific vaccines were available.
Anyone?
