My Bengal cat contracted calcivirus in September from new kittens we got from a rescue group. The kittens were not sick and had been vaccinated, but must have been carrying the virus. He was very sick, but recovered after a lot of support. I took him to the vet 12/23/08 to have his FVCRP vaccine to make sure he was protected in the future. Around a week later, he began to act like his joints hurt, had respiratory symptoms and was generally lethargic and not himself. He was eating and using the litter box, so I gave him 2 weeks for the symptoms to resolve. I thought maybe he just had a cold. I took him in today and the vet thinks he is having a recurrence of calcivirus. He had fever and other symptoms. He was given fluids and antibiotics.
My question is this--Is it possible that the vaccine caused this recurrence? I have heard that Bengals are especially sensitive to some vaccines. If not, how often can expect these recurrences and is it likely that my 3 other cats will catch this from him, if they are vaccinated yearly?
Thanks,
Marsha
