In the first edition it is on page 225 first column about halfway down and I did not accurately enough recall the numbers:
what it says is that after an outbreak occurs in ferrets who do not have sufficient immunity even if as many as 90% of the ferrets are vaccinated the disease will still infect a number, BUT if 70% or more were sufficiently immune then it was difficult to create an outbreak.
The reference is
Kelker, D
The effect of immunes on the spread of distemper in small ferret populations
Comput. Biol. Med.
10;53
1980
I knew it was in that edition so to save time did not check the second edition.
Sadly, there is no abstract at
http://www.ncbi.nlm.nih.gov/pubmed?term=Kelker%20distemper%20ferret
and I do not find it for free online.

When the majority of the ferrets were sufficiently vaccinated, 75 percent vaccinated, very few of the remaining UNvaccinated ferrets got CDV, but if 75 percent were UNvaccinated then the disease went through like wildfire. You can find it in the first edition of the text, Biology and Diseases of the Ferret, and I suspect that it is also mentioned in the second edition but lack time to look in them for you,especially tonight.
