With a dog so young, I would recommend taking her in for an exam because she can get dehydrated quickly with both vomiting and diarrhea. The cause could be a reaction to the vaccine (although less likely because it's her second round, and reactions would usually only take an hour or two), an infection, intestinal parasites, or it's very possible a cause won't be found. Some supportive care (some combo of fluids, anti vomiting and anti-diarrhea medication, bland food, and probiotics) can help her recover if no cause is found.
