This is bad. : (   Please read the ferret vaccination protocol at
http://www.ferret.org/vaccinations.htm
 
The vaccine you mentioned is not tested or approved for use in ferrets.
It may or may not be effective.  It may or may not be harmful.
 
Please have your vet procure the proper vaccines.  Note also, that to
insure canine distemper immunity you'll need to have him vaccinated and
then re-vaccinated two weeks later.
