We report a 44-year-old woman who presented with bilateral weakness of the hands and distal paresthesia of the arms on the next day of the second COVID-19 vaccine, and gradually progressed ascending weakness of the arms and legs, and sensory ataxia beyond 2 months. She was diagnosed as a chronic inflammatory demyelinating polyneuropathy (CIDP) following COVID-19 vaccine on the basis of clinical and electrophysiological findings. This is a first case diagnosed as a CIDP following COVID-19 vaccine alone.
