Overview

• At a White House cabinet meeting, HHS Secretary Robert F. Kennedy Jr. reiterated warnings about Tylenol in pregnancy and suggested a circumcision–autism connection he said was likely tied to acetaminophen, while President Trump urged women and newborns to avoid the drug.
• KFF’s new poll finds just 4% of Americans say the Tylenol–autism claim is definitely true, 35% say it is definitely false, and most fall into an uncertain middle with equal shares calling it probably true or probably false.
• The survey shows sharp partisan gaps: about 57% of Republicans versus 12% of Democrats say the claim is definitely or probably true, with Republican women notably more inclined to lean toward believing it.
• Trust in the CDC to provide reliable vaccine information has fallen to 50%, its lowest point since the pandemic, while 59% disapprove of Kennedy’s overall performance and 62% disapprove of his handling of vaccine policy.
• Major medical groups and Tylenol maker Kenvue say studies do not show a causal link and recommend acetaminophen as appropriate in pregnancy to treat fever and pain, warning that avoiding it can carry risks to the fetus.
