Guillain-Barr? syndrome is a disorder of acute polyneuropathy that is described as progressive, symmetric muscle weakness. Many reports have documented the occurrence of Guillain-Barr? syndrome after vaccination. Here, we report a very rare case of patient with Guillain-Barr? syndrome who presents with unilateral foot drop after receiving tatanus toxoid injection. Four days after the symptom onset, limbs weakness developed, and the patient showed delayed right peripheral facial palsy.
