Videos of people experiencing severe neurological symptoms, including convulsions and difficulty walking, purportedly after receiving a COVID-19 vaccine, have surfaced on Facebook, YouTube and other social media channels. The millions of people watching these videos might conclude that the vaccine is either quite dangerous to produce such symptoms or that the people in the videos are faking their symptoms. Both conclusions are incorrect, according to neurologist and psychiatrist David Perez, MD, MMSc, director of the Functional Neurological Disorders Unit at Massachusetts General Hospital (MGH).
