There are plenty of claims spread across the media that the COVID vaccine Pfizer can cause a multitude of health problems, including seizing or spasms. One video shared by James Cintolo, who claims in his Twitter bio to be a medical expert, shows a woman convulsing — he called the video “urgent” despite a Twitter fact-checking label noting the video is two years old — and it racked up 25 million views on the platform, inspired widespread mockery and a note from Twitter’s fact-checking team noting it “has been debunked by multiple news outlets and local and Federal health officials, showing no association … with the COVID vaccine,” according to multiple news outlets including a Wired investigation. Twitter users quickly turned these fake vaccine side effects into a meme: Many tweets, some simply captioned “Thanks Pfizer”—the caption from a widely derided Twitter video by Angelia Desselle labeled as misinformation that has been viewed more than 23 million times)—shows videos of characters from The Office doing a bizarre dance, or celebrities acting in a uncommon manner, garnering millions of views and hundreds of thousands of likes this week. Not only were celebrities joining in, but popular brands, like Duolingo, posted their own spin on the Pfizer side effect "joke".
