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.
A viral headline shared on social media falsely asserts that the Centers for Disease Control and Prevention changed testing thresholds to “virtually eliminate” COVID-19 cases among vaccinated individuals. That’s wrong. The threshold in question simply applies to whether or not there is enough virus present in a sample for further analysis.
The COVID-19 vaccine from Moderna uses an ingredient called SM-102 to deliver the mRNA that carries instructions for how to develop antibodies against the novel coronavirus. A widely shared video is now spreading the falsehood that SM-102 is harmful, but the warning label it shows is for chloroform, not SM-102.
Insurance companies do not deny claims when someone dies after receiving a COVID-19 vaccine, according to the American Council of Life Insurers. But a viral social media post has falsely claimed that beneficiaries of a person who dies after getting the vaccine cannot collect life insurance payments.
Federal health officials testified at a Senate committee hearing that about 60% of their employees have been vaccinated against COVID-19 so far. But viral online posts have distorted their comments to misleadingly claim that half of the employees “are refusing” the vaccines. The officials did not say anyone had refused to get vaccinated.
In a May 16 interview, the Centers for Disease Control and Prevention director said the agency knew of 223 breakthrough fatalities among fully vaccinated individuals, but “not all … died of COVID.” That is not an admission that “many, many hospitals” previously “overcounted” COVID-19 deaths, as conservative websites have reported.
A disagreement between Republican Sen. Rand Paul and Dr. Anthony Fauci has put $600,000 of U.S. grant money to the Wuhan Institute of Virology back into the spotlight, while making “gain-of-function” research a household term — all amid calls for more investigation into the origins of SARS-CoV-2.
Animal testing and clinical trials were conducted before the COVID-19 vaccines were authorized for use in the U.S. But a Texas state senator falsely claimed at a hearing that animal tests were “stopped” because the “animals were dying.”
The ingredients in the COVID-19 vaccines authorized for use in the U.S. are publicly available. Yet a false claim that the vaccines contain microchips is receiving renewed attention through a spate of videos of people claiming that magnets stick to their arms after vaccination. Experts say none of the ingredients would cause this supposed effect.
The Vaccine Adverse Event Reporting System accepts any reports of adverse side effects following vaccination to help regulators detect potential problems. Anyone can submit a report, whether or not the incident is vaccine-related. Fox News host Tucker Carlson misrepresented the VAERS data to suggest that thousands have died from COVID-19 vaccines.
So far, COVID-19 vaccines have been effective against variants of the coronavirus. Scientists are monitoring the situation carefully, with updated or new vaccines a possibility in the future, if need be.
