Recently, a vaccine called FVR C-P has come into popular use as a means of protecting cats against certain viral infections. This vaccine is prepared and distributed by Pitman-Moore. The interesting thing about the use of this vaccine, which perturbs me, is that it seems to be transmitted to humans. I saw two children in my office, one of whom had generalized swelling of the face that was followed, a week later, by a herpetic type of dermatitis on the nape of the neck.
