The decision undoes a highly effective 34-year prevention strategy that has nearly eliminated early childhood hepatitis B infections in the U.S.

The committee advising the Centers for Disease Control and Prevention on vaccine policy voted on Dec. 5, 2025, to stop recommending that all newborns be routinely vaccinated against the hepatitis B virus – undoing a 34-year prevention strategy that has nearly eliminated early childhood hepatitis B infections in the United States.

Before the U.S. began vaccinating all infants at birth with the hepatitis B vaccine in 1991, around 18,000 children every year contracted the virus before their 10th birthday – about half of them at birth. About 90% of that subset developed a chronic infection.
