Kathy--thanks for posting that info about the vaccine lot #32404. If you've used it with no trouble, sounds like the lot is all right. (My kids were the bunch that had trouble with it, btw.) At least now I can be certain what the problem is (allergy vs. bad batch of vaccine) and take appropriate measures the next time--like waiting around the office just to be sure and making certain the vet has epinephrine on hand, etc. [Posted in FML issue 1165]
