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.
