Hi all, I run a Shelter in Champaign, IL and have used FerVac since it was approved. I have given hundreds of vaccinations with FerVac and in the beginning did find a slight to moderate reaction to the dilutent that they used. This problem has since been rectified by United Vaccine. I have given over 40 injections with the Lot #32404, Expiration of 8/96 in the past couple of months with no reactions at all. I was wondering where the injections have been given? I give mine in the hip area (subcutaneously) and have had better results than giving the injection in the neck area. I also am a little sneaky when giving the injection. I place Ferretone on the table and let the ferret lick it off while giving the injection! They are so involved in the Ferretone that they don't know what has happened. This is easier on them and me both! Ferret hugs, Kathy Central IL Friends of Ferrets (CIFF) [Posted in FML issue 1164]
