A U.S. senator who has previously spread COVID-19 and vaccine misinformation claimed during an interview that masks don’t work, citing a 2020 Danish study. The study’s results were inconclusive, with the researchers emphasizing that “this trial did not address the effects of masks as source control or as protection in settings where social distancing and other public health measures are not in effect.” In the year since the study was published, other larger studies have demonstrated that masks are effective at reducing COVID-19 transmission.
