Trump Orders CDC to Rework Childhood Vaccine Schedule Using 2025 HHS Review
1 articles · Updated · University of Minnesota Twin Cities · Jun 11
Summary
Trump’s May 29 executive order tells the CDC and ACIP to use a December 2025 HHS scientific assessment as a guiding resource to realign the childhood vaccine schedule.
The move followed a May 19 ACIP charter revision that kept HHS Secretary Robert F. Kennedy Jr.’s broad control over committee membership and meeting schedules, setting up a more pliable advisory process.
Medical groups are already diverging from federal guidance: ACOG this week issued its own pregnancy vaccine schedule, backed by 13 organizations, recommending Tdap, RSV, flu and COVID-19 shots.
That split is feeding a state-by-state patchwork as at least a dozen states tie vaccine policy to groups like the AAP or to state health officials rather than the CDC.
The order does not directly violate Judge Brian Murphy’s March 16 stay, but AAP lawyers are watching for follow-on actions as federal vaccine guidance heads into a legally and operationally fragmented fall.

U.S. Childhood Vaccine Schedule Slashed: 2026 Legal Battle, State Resistance, and Public Trust Crisis
Overview
After Health Secretary Robert F. Kennedy Jr. took office in March 2025, he pushed to loosen vaccine regulations, leading the CDC to reduce the number of recommended childhood vaccines from 18 to 11. However, the Department of Health and Human Services bypassed proper procedures and appointed new advisory members who lacked required expertise. As a result, in March 2026, a federal judge blocked key parts of the new vaccine schedule. This decision created immediate uncertainty for healthcare providers and families, leaving the nation divided and unsure about which vaccine guidelines to follow.
