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 Pfizer document recently released by the Food and Drug Administration describes adverse events reported following vaccination and attests to the continued safety of the company’s COVID-19 vaccine. A popular video and other online posts, however, incorrectly imply that the vaccine caused the events.
The Centers for Disease Control and Prevention says it “recommends that children get four doses of polio vaccine.” But Rep. Marjorie Taylor Greene, when speaking against a potential fourth dose of the COVID-19 vaccines, wrongly suggested that the CDC doesn’t recommend four shots of the polio vaccine.
Dr. Anthony Fauci has continued making public appearances, although news coverage has largely shifted away from the pandemic since Russia invaded Ukraine in February and COVID-19 cases have dramatically fallen. Some politicians and pundits, however, have suggested that Fauci has become so unpopular that he has “disappeared” from public view. He hasn’t. Fauci has made at least a dozen public appearances since Feb. 15.
Randomized controlled trials haven’t found ivermectin is beneficial in treating COVID-19, although results for ongoing studies will provide a more definitive answer. Yet, a video presents two weak studies as “powerful” and “overwhelming” evidence that the medication works to combat COVID-19.
Plenty of peer-reviewed studies have found government restrictions early in the pandemic, such as business closures and physical distancing measures, reduced COVID-19 cases and/or mortality, compared with what would have happened without those measures. But conservative news outlets and commentators have seized on a much-criticized, unpublished working paper that concluded “lockdowns” had only a small impact on mortality as definitive evidence the restrictions don’t work.
The Centers for Disease Control and Prevention and Pfizer tweeted in February about the dangers of blood clots in veins, which are relatively common and affect as many as 900,000 Americans each year. A story shared on social media, however, misleadingly linked those public health reminders to the COVID-19 vaccines.
Studies have shown that COVID-19 vaccines have prevented severe disease and deaths. But bogus claims that they don’t work continue to circulate online. One claim relies on a misleading graph showing cumulative deaths in the U.S., but omits information about the number of deaths among the vaccinated versus unvaccinated since the shots became available.
Rare cases of myocarditis have been reported following the mRNA COVID-19 vaccines, particularly among young males after a second dose. Most cases resolve quickly without the need for advanced therapies, although research on any potential long-term effects is ongoing. Nonetheless, the benefits of vaccination outweigh the risks in all populations, even in young males.
Clinical and real-world studies have shown that the COVID-19 vaccines are effective in preventing serious disease, and there is a long history of vaccine requirements in the U.S. But a list of bogus claims, shared around the world in recent months, falsely attributes unique characteristics and requirements to COVID-19 vaccines.
As of early December, unvaccinated adults were about 97 times more likely to die from COVID-19 than fully vaccinated people who had received boosters, according to Centers for Disease Control and Prevention data. But a Twitter user falsely implied that the death rate for the unvaccinated included people who had only one or two doses of a vaccine. The CDC said “unvaccinated” means someone has “not been verified to have received COVID-19 vaccine.”
