Sorry to hear that your baby passed away, Lori. I too experienced a problem with Fervac D. My baby received his third vaccine and we almost lost him. He became very limp, would not eat or drink for two days (even turned down baby food and cheese, his favorites). The vet said there is something they can give him to counteract the reaction to the vaccine, but I am very hesitant to get his distemper vaccine next year. Anyone know if I should use Fervac D again or find another product? [Posted in FML issue 2228]
