Twitter placed a sharing restriction over a graphic taken from a CDC presentation: A user tweeted a screenshot from a CDC presentation that linked Myocarditis/Pericarditis with COVID-19 vaccines. The screenshot highlighted a section that read: "Evidence from multiple safety monitoring systems in multiple countries supports the finding of an increased risk of myocarditis and myopericarditis following mRNA vaccination." Twitter placed a sharing restriction on the tweet preventing users from commenting on, liking, retweeting, or sharing the tweet on other sites. Users can only quote tweet the post. Other instances of the same content and quote have not received similar restrictions.
