Antivaccine activists use a government database on side effects to scare the public

On 5 May, Fox News host Tucker Carlson delivered a 10-minute monologue casting doubt on the safety of COVID-19 vaccines on his show, Tucker Carlson Tonight. He announced that almost 4000 people had died after getting COVID-19 vaccines, and added that those data “comes from VAERS,”—the Vaccine Adverse Event Reporting System, a U.S. government program that collects reports of side effects possibly caused by vaccines. It was a misleading statement. The reporting of a death to VAERS indicates nothing about what caused it, and the Centers for Disease Control and Prevention’s (CDC’s) subsequent investigations have found no indication that deaths were caused by COVID-19 vaccines, save in a small subset with an extremely rare clotting disorder linked to one vaccine. But the TV segment pulled VAERS, a 31-year-old early warning system widely relied on by scientists, even deeper into the culture wars over vaccination. After the broadcast, a new phalanx of antivaccine activists began plumbing VAERS for data to scare the public about vaccination, says Angelo Carusone, president of Media Matters for America, a left-leaning nonprofit that is monitoring anti–COVID-19 vaccine activity on social media. “We have been tracking these attacks since February and this one resonated in a different way after Tucker hit it,” Carusone says.
