Vaccinosis can take a lot of different forms, the commonest being itchy allergic skin or ears. But, the interesting thing is, we'll often see symptoms of the disease vaccinated against, just now in a chronic disease state.
So, rabies being a behavioral virus, we see behavioral changes, yes. And parvo, being mostly a gut virus, we'll see gut changes (chronic diarrhea, or IBS, or vomiting/regurg). Distemper being a nervous system and respiratory disease, we can see quite a spread of symptoms.
If you titer test for rabies again, maybe a month from your first one, and see nothing, and if rabies is a risk worth worrying about where you live, I'd give a second vax. Don't re-titer for 3-4 weeks after that one.
(There really isn't a "natural exposure" titer to this, as the virus travels via saliva, so it takes a bite of a rabid animal to get exposure)
