Sometimes vaccines can result in some discomfort and lethargy, but usually only for 24 hours or so afterwards. If it has been longer than that since she was vaccinated it is unlikely to be due to the vaccines. If one pupil is consistently larger than the other that is abnormal however and I would recommend you take her back to the vet to be checked out.
