Hi All! The batch of fervac-d that has cause reactions in 3 ferrets who had never had reactions before is Ser.32402/73403 exp. Feb. 2, 1996 My vet has reported it to United Vaccines, but please check if you are getting a distemper vaccine that it is not this batch. Both of my ferrets reacted very badly, and had had fervac-d with no problems before, and then another vet in the same practice, who had been on vacation when mine reacted, did not see the note saying do not use, and vaccinated another ferret, and got another nasty reaction, so we are pretty convinced that something is wrong with that batch..... krystal weehawk and silk [Posted in FML issue 1287]
