The Centers for Disease Control and Prevention director on Friday recommended that pregnant people get the COVID-19 vaccine, citing a new study that suggests there is no evidence that the shot causes safety concerns for pregnant people or their babies. Speaking at a White House COVID-19 briefing, CDC head Dr. Rochelle Walensky acknowledged that none of the participants in initial trials of the COVID-19 vaccines were pregnant, leaving doctors and families with little data on how the new shots would impact patients or their pregnancy. But emerging self-reported data from the first months of the U.S. vaccine rollout has led researchers to suggest that the new vaccines do not pose increased risk during pregnancy.
