FactCheck.org’s SciCheck feature focuses exclusively on false and misleading scientific claims that are made by partisans to influence public policy. It was launched in January 2015 with a grant from the Stanton Foundation. The foundation was founded by the late Frank Stanton, president of CBS for 25 years, from 1946 to 1971.
All of the authorized COVID-19 vaccines are effective at preventing symptomatic disease. Yet Fox News host Tucker Carlson baselessly casts doubt on the effectiveness of the vaccines, because federal officials urge fully vaccinated people to wear masks in public settings.
Nearly 200 million doses of COVID-19 vaccines have been administered in the U.S., including 7.2 million doses of the Johnson & Johnson vaccine. The CDC and FDA recommended “a pause in the use” of the J&J vaccine “out of an abundance of caution” because of six cases of a rare type of blood clot.
Viral social media posts cite a flawed paper in falsely claiming the Centers for Disease Control and Prevention changed death certificate procedures and violated federal law, resulting in wildly inflated COVID-19 deaths. The CDC hasn’t altered how death certificates for COVID-19 are filled out, and there is no federal law governing the process.
Social media posts repeatedly misuse unverified data from the Vaccine Adverse Event Reporting System to falsely claim that COVID-19 vaccines are dangerous, and even lethal. But the government database is not designed to determine if vaccines cause health problems.
A video making the false claim that the Pfizer CEO “refuses” to get a COVID-19 vaccine has been circulating on Facebook. But the pharmaceutical company’s chief executive has said that he’s gotten his first shot.
Federal officials authorized two mRNA vaccines for COVID-19 after they were determined to be safe and effective against symptomatic illness in clinical trials. But a Texas doctor, in a widely shared video, falsely claims the vaccines don’t provide protection and that they’re actually “experimental gene therapy.”
A study from the Centers for Disease Control and Prevention found that state-issued mask mandates were associated with significant decreases in daily COVID-19 case and death growth rates. Yet some conservative outlets and social media users falsely claim the study shows mask mandates have a negligible impact on COVID-19 outcomes.
A Food and Drug Administration presentation on monitoring the safety of COVID-19 vaccines listed possible adverse events the agency might track. But an Instagram post misrepresents the document, falsely claiming it shows the vaccines are known to cause harmful side effects — including death.
Hall of Fame boxer Marvelous Marvin Hagler “died on March 13 of natural causes,” according to a statement posted on his official website. In a Facebook post, his widow, Kay Hagler, wrote that his death was not the result of a COVID-19 vaccination.
A video stoking fears of the COVID-19 vaccines in the Black community is being promoted online. But the film repeats misrepresentations about vaccines, generally, and exploits historical cases of unethical medical conduct to suggest without evidence that COVID-19 vaccines are unsafe.
