The secretary of defense announced that COVID-19 vaccination will be mandatory for all service members by mid-September. But social media posts have shared an article from a dubious website that falsely claimed that the leader of the Marines “rebuked” the vaccine mandate. A Marine Corps spokesperson told us “there is no truth” to the claim.
A Centers for Disease Control and Prevention document reviews the challenges of using a “shielding” approach to protect high-risk people living in places such as refugee camps from COVID-19. But conservative commentator Candace Owens misinterpreted it to mean the agency was proposing putting high-risk Americans into camps.
A growing body of evidence supports the use of masks to slow the spread of COVID-19. But the effectiveness of masks is now being challenged again. Here we summarize some of our work over the past 16 months, based on categories of misinformation about masking.
In a viral video, an Indiana physician baselessly claimed that the COVID-19 vaccines, which have been shown to be safe and effective, “fight the virus wrong and let the virus become worse than it would with native infection.” He also incorrectly said no vaccine prevents infection and contended that people previously infected with COVID-19 do not benefit from vaccination, despite studies that suggest otherwise.
The CEO of Pfizer posted a photo of himself getting the second shot of the COVID-19 vaccine on March 10. But an Aug. 5 tweet from Newsmax reporter Emerald Robinson misleadingly suggested he isn’t vaccinated. She updated the tweet hours later, acknowledging the CEO’s post — but after her claim had spread, uncorrected, on other social media.
Researchers use genomic sequencing — not the clinical tests used to diagnose patients with COVID-19 — to identify and track specific variants of the novel coronavirus, SARS-CoV-2, including the highly contagious delta variant. But viral posts try to deny the existence of the variant by misleadingly claiming there is “no ‘Delta Variant’ test.”
Florida health officials have reported a 60% rise in COVID-19 cases, and hospitals are reporting that 95% of COVID-19 patients are not fully vaccinated. But a Facebook post makes the baseless claims that Florida’s numbers are not going up, and that all COVID-19 patients recently admitted to a Palm Beach County hospital had been vaccinated.
The Biden administration hasn’t introduced COVID-19 travel restrictions on Americans going to Mexico since the delta variant became dominant in the U.S., and it is enforcing immigration laws at the border. But a meme falsely claiming the opposite is circulating online.
Citing new data on the delta variant, the Centers for Disease Control and Prevention recommended that fully vaccinated people wear face masks indoors in some parts of the country.
A conspiracy theory online baselessly suggests that the World Health Organization and other groups preplanned the variants of the novel coronavirus — citing a dubious timeline. But the timeline doesn’t square with the reality of when variants have been identified and designated thus far.
