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.
Following the assassination of Haitian President Jovenel Moïse, social media posts baselessly suggest that he and other world leaders were killed or died because they opposed COVID-19 vaccination in their countries. All the leaders named in the posts, except Moïse, died of natural causes. At least one supported vaccination.
There is no evidence that a door-to-door campaign to encourage vaccinations against COVID-19 means President Joe Biden and Democrats “are coming to your front door to force you to take the vax,” as Rep. Marjorie Taylor Greene tweeted. She also cited a figure for reported deaths after vaccination, which is not the same as deaths caused by vaccination.
The delta variant of the virus that causes COVID-19 spreads more quickly than the original virus and has been classified as a “variant of concern” by the World Health Organization. It is now the dominant variant in the U.S. But a meme has been circulating on Facebook falsely claiming the delta variant is “fake news.”
A list of the ingredients used in COVID-19 vaccines is publicly available, and the ingredients don’t include microchips. Yet claims advancing conspiracy theories that they do continue to flourish. A recent video purports to show a microchip reader for pets detecting a chip in a vaccinated person’s arm — but the original video was created as a joke.
The COVID-19 vaccines have been shown in trials and real-world application to be safe and effective. But a paper shared widely online claimed that vaccines cause two deaths for every three lives saved. Experts say the analysis misinterpreted data and was flawed — and it has now been retracted by the journal that published it.
Randomized controlled trials — the highest standard of evidence — have found that hydroxychloroquine isn’t beneficial in treating hospitalized COVID-19 patients. Yet social media posts are claiming the drug works, and conservative outlets have touted an unpublished, and much-criticized, observational study as evidence of the drug’s effectiveness.
There is no evidence to indicate that the spike proteins generated by human cells following vaccination are a toxin or that they circulate in the body and damage tissues, contrary to what a Canadian virus immunologist recently claimed.
Following the deaths of four British Airways pilots and five Air India pilots, social media posts claimed without proof that the pilots died as a result of receiving COVID-19 vaccines. Air India said its pilots died from COVID-19. British Airways said “there is no truth whatsoever in the claims on social media speculating that the four deaths are linked.”
A World Health Organization advisory group has concluded that the Pfizer/BioNTech vaccine “is suitable for use by people aged 12 years and above,” and is specifically recommending it for children ages 12 to 15 who are at high risk of severe COVID-19. The WHO did not say “stop giving kids the vaxx immediately,” as some have claimed online.
Despite increased media attention to the possibility that the novel coronavirus may have escaped from a lab, no credible evidence has emerged to support it and most scientists think the virus likely has a natural origin.
