Political and Policy Context
The split follows a controversial decision by the CDC’s advisory panel in December to delay the first dose of the hepatitis B vaccine for certain newborns. The panel, appointed by Health and Human Services Secretary Robert F. Kennedy Jr., voted to recommend postponing the shot until two months of age for infants born to mothers who test negative for the virus.
Kennedy, a longtime critic of vaccine policy, has said vaccines remain available and fully covered, though he acknowledged additional steps are now required for some immunizations, including influenza.
Public health experts have warned that inconsistent messaging could undermine confidence in routine vaccination and increase the risk of outbreaks.
AAP Warns of Public Health Risks
In a statement, the AAP said it no longer collaborates with the CDC on a unified vaccine schedule, citing concerns that the revised federal guidance departs from established science and weakens disease prevention efforts.
The CDC, under the Department of Health and Human Services, defended its approach, saying the updated schedule maintains protection against serious illness while aligning U.S. policy with international standards.
As pediatricians prepare to implement the AAP guidance, both organizations say continued dialogue with families will be critical to navigating the evolving vaccine landscape.
