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.
Sports medicine experts say there has been no increase in sudden death or cardiac injury among U.S. athletes since the COVID-19 vaccines became available. Yet anti-vaccine campaigners, comparing unreliable numbers to an unrelated study, have again spread a false narrative about vaccine safety since NFL player Damar Hamlin suffered cardiac arrest.
Buffalo Bills player Damar Hamlin collapsed on the field and suffered a cardiac arrest moments after taking a hit to his chest during a tackle. While it’s not yet known why his heart stopped, some experts say his condition is most likely due to a heart rhythm problem as a result of that impact. Still, people on social media have baselessly speculated that it was caused by a COVID-19 vaccine.
Several European countries have reported an early spike of group A strep infections, mostly among children, including cases of rare but deadly bacterial infections. There is no evidence the increase is being caused by nasal spray flu vaccines, as social media posts baselessly suggest. Flu vaccination may even indirectly prevent strep A.
A vaccine safety surveillance study from the Food and Drug Administration has been misrepresented online. The paper did not establish a link between the Pfizer/BioNTech COVID-19 vaccine and blood clots, as some have claimed — and to date, other, more robust research has not identified such associations.
While announcing a request for a grand jury probe into “crimes and wrongdoing” related to the COVID-19 vaccines, Florida Gov. Ron DeSantis and his panel of contrarian experts repeatedly suggested the shots were too risky. But such claims are unsupported and based on flawed analyses.
To date, the benefits of COVID-19 mRNA vaccination outweigh the risks, which include a rare but increased risk of myocarditis, or heart inflammation. Social media posts, however, are citing a German autopsy study to misleadingly suggest otherwise.
American sportswriter Grant Wahl died unexpectedly while covering the soccer World Cup in Qatar, and purveyors of vaccine misinformation have suggested that his death was caused by COVID-19 vaccination. He actually died from the rupture of an aortic aneurysm that he didn’t know he had.
A blood transfusion from a vaccinated person doesn’t transfer the inoculation to an unvaccinated person. But high-profile purveyors of misinformation have been promoting the long-standing false claim that it does.
Country singer Jake Flint died unexpectedly on Nov. 27, just hours after his wedding. Social media posts baselessly insinuate Flint died because of the COVID-19 vaccine. The 37-year-old singer received his second dose more than a year before his death, and his representative said Flint’s death was “not related in any way” to the vaccine.
What appear to be ordinary postmortem blood clots are held up in a viral online video as supposed evidence that there’s a depopulation plot underway using COVID-19 vaccination to kill people. There’s no evidence for this theory. The hourlong video also repeats numerous falsehoods that have previously been debunked.
