The VAERS database, which is managed by the Food and Drug Administration and the C.D.C., has been cited in many coronavirus falsehoods to push the idea that side effects from the Covid-19 vaccines have been underreported.
A spokeswoman for the F.D.A. declined to comment, but pointed to an overview of the VAERS database on the F.D.A.’s website that said VAERS reports “generally cannot be used to determine if a vaccine caused or contributed to an adverse event or illness.”
In March, Twitter introduced a policy that explained the penalties for sharing lies about the virus and vaccines. People who violate that policy are subject to escalating punishments known as strikes and could face a permanent ban if they repeatedly share misinformation about the virus.
Ms. Greene won the primary election for Georgia’s 14th Congressional District in August 2020, after rising to prominence by posting unabashed support for President Trump and for QAnon, a movement tied to the baseless conspiracy theory that a group of global liberal elites run a child sex ring that Mr. Trump would stop.
Ms. Greene repeatedly posted the QAnon slogan on Facebook and Twitter and had previously called “Q” — the anonymous online account that set off the QAnon conspiracy movement — a “patriot” who was “worth listening to.” Last year, Ms. Greene heavily promoted the false claim that the 2020 presidential election was stolen from Mr. Trump, tweeting in January that there was “MASS voter fraud on a scale that should terrify every American regardless of political party.”
But it was Ms. Greene’s false proclamations about the coronavirus, including opposing vaccines and masks as tools to curb the pandemic, that finally got her suspended from Twitter. In July, Ms. Greene argued that Covid-19 was not dangerous for people unless they were obese or over age 65, and said vaccines should not be required.
In August, Ms. Greene said on Twitter, “The F.D.A. should not approve the covid vaccines.” She said that there were too many reports of infection and the spread of the coronavirus among vaccinated people, and that the vaccines were “failing” and “do not reduce the spread of the virus & neither do masks.”
