These are my opinions on these subjects. First let me say that there is nothing wrong with the Avecon saliva tests. I feel that they are more accurate than the United tests that everyone has been doing. Why you may ask? Because when I had called a few years ago and inquired why a test could come up inconclusive they explained that many things could throw the test off. This means that if your ferret has a cold or the flu it could throw a false positive. If your ferret has cancer or had it's distemper or rabies vaccines done to close to the time of sample taking it could throw a false positive. If there is something on the ferrets foot when a sample is taken it could throw a fale positive. To me Avecon is more thorough and more accurate, besides isn't it better to use the company WHO DEVELOPED the ADV test rather than a copycat company? Second, I was told that after January 25th that not only is United NOT doing ADV testing anymore, but they will no longer be manufacturing Fervac D or Purevax. Both these vaccines are known for their higher percentage rate of reactions, where as Galaxy D has little to no reactions when given to a ferret for vaccination against canine distemper. Besides I would rather use the same vaccine as Dr. Bruce Williams who is a well renowned and well respected ferret vet. If Galaxy D is what he uses on his ferret paceints than that's good enough for me. Galaxy D has been around a lot longer & has been used on many more ferrets than the other two vaccines combined, so I feel it has proven it's worth in guarding our ferret against contracting the canine distemper virus. I will continue to use Avecon to test my ferrets for ADV as I have always felt it was more acurate, and will continue to use Galaxy D (the only vaccine I trust) to vaccinate my ferrets against the canine distemper virus. This is how I feel and is my opinion on this subject. Flame if you must, but this is my right to freedom of speech! [DV] [Posted in FML issue 5113]
