This may not be from the vaccination, however if she had a lot of worms, the worming tablet killed all or most of them. This can cause diarrhea as the body wants to get rid of the dead worms. Try feeding her some fishy canned food and add a bit of pumpkin. If your kitten appears ill, lethargic, then she should be seen by a vet , preferably today (since we have a weekend coming up). If she is lively, playful and does not appear sick, feeding her the wet food with a little bit of pumpkin may alleviate the diarrhea. If this does not happen by Monday, she will need to be examined by your vet.
