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.
Vaccination and infection both provide protective immunity to COVID-19, particularly against severe disease. But gaining immunity through infection is far riskier than vaccination. Posts citing a new Lancet study omit that important context and also misleadingly claim the study shows immunity after infection is superior to vaccination immunity.
Members of the World Health Organization are in the process of developing a new agreement to prevent, prepare for and respond to pandemics. A preliminary draft presented in February reaffirms nations’ sovereign right to make their own health policies during global pandemics, contrary to false claims online.
Most U.S. intelligence agencies assess a spillover from an animal is most likely the origin of COVID-19, but recent news reports say the Energy Department now favors the lab-leak hypothesis. Online posts wrongly claim this means a lab origin has been confirmed.

Health problems that are reported to the Vaccine Adverse Event Reporting System after vaccination are not necessarily caused by a vaccine. Yet social media posts distorted a comment from a Centers for Disease Control and Prevention official about such reports to falsely say he admitted the vaccines cause “debilitating illnesses.”
Moderna’s CEO said in January that the company’s total production in 2019 was “100,000 dose,” referring to all its vaccines and therapeutics. Online posts distorted the remarks to falsely claim Moderna made COVID-19 vaccines “before the pandemic started.” Moderna’s first batch of COVID-19 vaccines wasn’t ready until February 2020.
Thai officials attributed the collapse of the king’s eldest daughter in December to a bacterial infection, not to COVID-19 vaccination, as some have baselessly claimed online. Rumors about the country banning Pfizer’s vaccines are also “fake news,” officials said.
Pregnancy tests contain a desiccant tablet to absorb moisture and keep the test dry before use. But posts on social media falsely claim the tablet is a “hidden plan B” pill. Companies that produce pregnancy tests include a warning on their websites not to consume the desiccant tablets inside.
Research suggests COVID-19 vaccination can cause changes in a person’s menstrual cycle. But the changes are small and short-lived — and studies have shown there’s no effect on fertility. Yet people on social media are suggesting the cycle changes are evidence of harm.
