Such a reaction to vaccinations are not completely uncommon, these usually resolve without treatment within 24 hours. if it has been more than 24 hours and she is still not herself i would advise you to contact your vet, sometimes pain killers are needed. in some more rare cases vaccination reaction can cause more long lasting issues, but this is extremely rare.
