Thanks Sukie, I had been asking if we had any follow-up info on this vaccine but never got an answer with any published info since Bob Wagner presented at the Symposium. So it was very good news to read this. For those wanting more specific info regarding the vaccine study you can use this link. Thanks again BIG for setting this up for us through your involvement in the IFC. <http://www.ferretcongress.org/sym2011/phxpdf/Ferret%20GnRH%20vaccination%20ACD%20prevention-Wagner.pdf> Once you link in go to Robert Wagner's info on adrenal. The study specifics are available there in the power point. In Jackie D's comments in the yahoo link form Sukie, if I am recalling this right, one of the reasons for the lumps forming when they first began to administer the vaccines was that prep had not been done in sterile conditions. Once they changed that they did not run into lumps developing at injection site. Hopefully, the manufacturers and participating vets will keep prices low enough for this to be affordable for the average ferret owner. Cathy Ryan Today is the best day to do a good deed.
