I have a question that has been bothering me recently concerning the
distemper vaccines.  It's my understanding that the Ferrvac and Galaxy
vaccines consist of a modified live virus.
 
Have there every been any studies or is there any suspicion that the
modified virus is as "contagious" as the distemper virus?  Can unvaccinated
ferrets gain any protection by "catching" the modified virus?
 
My concern is with my ferrets that have had severe reactions to the CDV.  I
probably won't be able to re-vaccinate those, and I am wondering if there
would be any advantage with putting them with recently vaccinated ones in
the hope of some of the immunity being transferred.
