A roundup of some of the most popular but completely untrue stories and visuals of the week. None of these are legit, even though they were shared widely on social media. The Associated Press checked them out. Here are the facts:

Swedish study on COVID vaccines and DNA misinterpreted
CLAIM: A Swedish study shows that Pfizer’s COVID-19 vaccine changes recipients’ DNA.
THE FACTS: The study, conducted by researchers at Lund University in Sweden, tested whether the vaccine’s mRNA could be converted to DNA, and found that this was the case in certain lab-altered liver cell lines under experimental conditions. It did not assess whether the vaccine alters the human genome, or what the effects of that would be. But social media users are citing the February study to push the unproven theory that mRNA COVID-19 vaccines permanently alter recipients’ DNA. A clip from March that is being reshared online in recent days shows three doctors, who have spread misinformation about the vaccines in the past, discussing the Swedish study and falsely claiming it demonstrates that “the Pfizer vaccine reverse transcribes and installs DNA into the human genome." The genome is the set of instructions to build and sustain a human being. Other social media users commented that the paper proves mRNA COVID-19 vaccines “change the recipient’s DNA.” Experts say such interpretations mischaracterize the work and draw inaccurate conclusions. The study authors clarified their research in a Q&A, stating that “this study does not investigate whether the Pfizer vaccine alters our genome," adding that “there is no reason for anyone to change their decision to take the vaccine based on this study." DNA is the building block of the body’s genetic code. RNA is closely related to DNA, and one type,...
