Adherents of far-right groups who cluster online have turned repeatedly to one particular website in recent weeks — the federal database showing deaths and adverse reactions nationwide among people who have received Covid-19 vaccinations.
Numerous channels link to the government website called VAERS, for Vaccine Adverse Event Reporting System, to energize followers. It had reported 2,216 deaths among people vaccinated for the three months before March 22, with 126 million doses administered. The Covid-19 vaccines in use, like most vaccinations, are considered overwhelmingly safe, but inevitably a small percentage of recipients suffer adverse reactions, some of them severe. The deaths have not been directly linked to the vaccinations.
