Yes, that's pretty much what my vet told me today when I asked about it. He said that it depended on how virulent a strain the virus was, and if the cat was stressed in any way, and also that no vaccine has a 100% success rate. He still thinks that the virus came from one of the new cats rather than outside. I will just have to watch and wait. I still need to let the shelter know what happened.
