False claims about miscarriage risk from Covid-19 vaccines are spreading online. They use a faulty interpretation of data | CNN

Numerous studies have shown that Covid-19 vaccines are safe during pregnancy, but Republican senators have recently stirred up false and misleading claims that are now spreading on social media. On Monday, Sens. Ron Johnson of Wisconsin and Rand Paul of Kentucky released a batch of text messages retrieved from Dr. Anthony Fauci’s former government phone as part of an investigation into the former health official’s leadership and actions during the Covid-19 pandemic – including messages in which he discusses the possible risks and safety of the vaccine during pregnancy. These messages were a launching pad for the spread of inaccurate data, particularly claims about an 82% risk of miscarriage associated with Covid-19 vaccines. The incorrect figure spread online, including in a since-deleted post by Sen. Ted Cruz. “This is a well-studied area.
