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 study showed a type of lab mouse is highly susceptible to a coronavirus derived from pangolins, a scaly, cat-sized mammal. This doesn’t mean the virus is dangerous to humans. The virus is related to the one that causes COVID-19 but did not descend from it, contrary to claims that it is a “mutant COVID-19 strain.” Nor did scientists “craft” the virus.
Measles is a highly contagious disease that can be serious and even fatal. Fortunately, it can safely be prevented by vaccination. But in the wake of outbreaks in the U.S. and elsewhere — likely in large part due to low vaccination coverage — social media posts have downplayed the risks of measles and falsely claimed the vaccine “is more dangerous than the actual illness.”
The World Health Organization began using the term “Disease X” in a 2018 planning document to refer to a “currently unknown” illness. But since the term was used at the January meeting of the World Economic Forum, conspiracy theorists baselessly claim Disease X is part of a “Globalist Plan to … Install World Government.”
COVID-19 vaccination during pregnancy benefits both mother and baby. Side effects are generally mild, and studies don’t show negative effects on the baby. A criticized study that gave COVID-19 vaccines to pregnant rats doesn’t show that vaccines cause autism or that people shouldn’t get COVID-19 vaccines, contrary to claims.
COVID-19 vaccines are generally safe and have not killed 17 million people worldwide, contrary to claims amplified by podcaster Bret Weinstein during an interview with Tucker Carlson. Weinstein also inaccurately characterized a proposed World Health Organization pandemic accord and other changes, claiming they aim to take away “personal and national sovereignty.”
The COVID-19 vaccines have saved millions of lives, according to multiple studies. Despite this, Florida Surgeon General Dr. Joseph Ladapo issued a statement on Jan. 3 calling for a halt in the use of mRNA COVID-19 vaccines, made by Pfizer/BioNTech and Moderna.
Kate Cox petitioned to be allowed to have an abortion in Texas to “protect her life, health, and future fertility,” after receiving news that her baby was unlikely to survive, according to her court filing. A popular Instagram post misrepresented Cox’s specific case and also made misleading claims about trisomy 18, the condition affecting her pregnancy.
A preprint on a Yale-based study described chronic symptoms self-reported after COVID-19 vaccination by 241 members of an online group. The paper, which has not been peer-reviewed, did not show how common these symptoms are in the general population, nor whether vaccinations caused them — limitations popular online posts did not make clear.
Data from around the world support the general safety of the COVID-19 vaccines. Some people online, however, incorrectly claim that illegally obtained data from New Zealand show the vaccines have killed 13 million people worldwide. Experts say the analysis is bogus.
People who receive some vaccines that use live weakened viruses to stimulate a strong and lasting immune response sometimes release small amounts of those viruses outside of their bodies. That’s expected, and it doesn’t mean that they put vulnerable populations in “harm’s way,” as a post misleadingly suggests.
