(Forbes) False claims that Covid-19 vaccines cause spasms have gone viral on social media, with many users — even language education company Duolingo — making an even more viral joke out of the misinformation.
Anti-vaxxers are spreading videos on social media of people appearing to seize or spasm, falsely claiming these to be Covid-19 vaccine side effects — but in many cases the videos are years old, unrelated to the Covid-19 vaccine and have been debunked by fact-checkers.
Spasms and seizures are not listed as either common side effects or adverse side effects of the Covid-19 vaccine, according to the Centers for Disease Control and Prevention, and the CDC emphasizes the vaccines are safe and effective.
