ACIP's Hepatitis B Birth-Dose Reversal Puts U.S. Newborn Vaccine Policy Under Strain
SHERIDAN, WYOMING - December 8, 2025 - The CDC's Advisory Committee on Immunization Practices (ACIP) has triggered a major shift in U.S. newborn immunization policy, voting 8-3 to delay the hepatitis B vaccine for infants born to hepatitis B-negative mothers from the traditional birth dose to two months of age, despite decades of evidence and CDC messaging that the shot is safe, effective and critical for long-term protection.
A Narrow Vote to Delay the Birth Dose for Some Newborns
Under the new recommendation, only babies born to mothers who test positive for hepatitis B-or whose status is unknown-would still receive the birth dose. For infants of mothers who test negative, the vaccine can be delayed until two months, effectively dismantling the universal birth-dose strategy that has been in place for about 30 years.
