Robert F. Kennedy Jr., a prominent anti-vaccine advocate, is running for president as a Democrat. Our SciCheck team has combed through his recent interviews to identify and correct some of his most common health claims in a three-part series. In this first installment, we address several of his talking points about vaccines.
It remains unknown how the virus that causes COVID-19 originated, but many scientists think a natural spillover is most likely. Online posts have cited unnamed sources to claim that scientists in Wuhan, China, were the first to get sick with COVID-19. But U.S. intelligence says the researchers’ symptoms were non-specific or inconsistent with COVID-19, and the information has no bearing on the origin of the pandemic.
Last summer saw the largest outbreak ever of mpox, the disease formerly known as monkeypox. Here, we provide an update on the disease, and explain what makes the outbreak unusual and how people can protect themselves.
For decades, the Vaccine Adverse Event Reporting System, or VAERS, has been exploited by people opposed to vaccination. Here, we’ll explain how VAERS works and run through five misconceptions that anti-vaccination activists wield to mislead people about vaccines.
We fact-check Florida Gov. Ron DeSantis’ claims in two public appearances announcing his 2024 presidential candidacy.
More than half of abortions in the U.S. are medication abortions, done early in pregnancies. But federal court rulings have raised questions about the future availability of mifepristone, the first of the two-drug combination used in those abortions. Here we answer questions about the court rulings, mifepristone and what may happen next.
Outside of long COVID or very severe cases, most research suggests COVID-19 doesn’t cause lasting damage to the immune system. A few studies have found evidence of some possible damage, but nothing as severe as an immunodeficiency. People on social media, however, are misinterpreting a recent study to incorrectly claim COVID-19 is HIV-like.
People online are touting the results of a Cochrane review to incorrectly claim that it shows masks “don’t work” against the coronavirus. But the primary conclusion of the review is that it’s uncertain from randomized controlled trials whether mask interventions in the community help slow the spread of respiratory illnesses.
Scientists say the experiments Pfizer has performed on the coronavirus are standard for the industry. Baseless claims that the company is mutating the virus for profit, however, have been circulating since the release of a popular undercover video from the conservative activist group Project Veritas.
The derailment of a freight train carrying toxic chemicals in eastern Ohio has sparked a slew of unfounded claims by conservative commentators. There’s no indication that this incident will rise to the level of a “domestic Chernobyl”; it has been covered steadily by the media; federal and state agencies are monitoring air and water quality and its impact on people and animals.
