Tiffany Dover was one of the first Americans to get the COVID vaccine—and she got it live on camera, at the hospital in Chattanooga, Tennessee, where she works as a nurse. “I'm sorry, I'm feeling really dizzy. I'm sorry,” Dover said while taking questions afterward. Then she fainted. Twenty minutes later, Dover was back in front of the camera. “I feel fine now,” she said. And she was totally fine. But thousands of people online had already made up their minds: Tiffany Dover was dead. And they were going to prove it.
