I was swayed by the vet last year as well and let them dual vaccinate my two kids. My vet told me that she hadn't seen any problems with it and lots of folks did it. To be fair, she also told me that some swore by vaccinating separately. She then let me make the decision. NEVER AGAIN. Mine had vaccine reactions - Bandit's so severe that we almost lost him. Vomiting, bowel control loss, convulsions. At least I knew to stay at the vets....the reactions occurred about 25 minutes after the vaccination. I still haven't forgiven myself for what Bandit went through. He is my sweet kissy boy and we almost lost him because of my decision. To top it off, now I don't know which vaccination he reacted to. Was it the Imrab or the Galaxy D (they couldn't get Fervac at the time)? It is now time again for their annual vaccinations and I am loathing going to the vets. We will pretreat and give them separately with a few weeks apart. I know others have given the vaccinations together with no problems.....but think carefully before you make that decision. You're taking a chance that you'll kill your ferret. Can you live with those odds? Take the extra time and effort to vaccinate separately....it will give you peace of mind and perhaps save the life and well-being of your ferret. Don't take risks with the lives of your ferrets!
