Dysphagia after COVID-19 Vaccination: A Report of Two Cases

Various adverse reactions to COVID-19 vaccination have been reported; however, no case reports have focused on dysphagia. We herein present two cases of severe dysphagia after COVID-19 vaccination. Case 1: A 24-year-old man with Burkitt's lymphoma developed dysphagia and multiple cranial nerve palsies. Case 2: An 80-year-old man with Parkinson's disease developed aspiration pneumonia and dysphagia. Both patients underwent a detailed dysphagia evaluation and swallowing rehabilitation. According to the Vaccine Adverse Event Reporting System, dysphagia following COVID-19 vaccination is very rare. Clinicians should be aware of the appearance or worsening of dysphagia following COVID-19 vaccination.
