President Donald Trump has signed an executive order directing a federal review of the nation’s childhood immunization framework, instructing health officials to reassess vaccine recommendations through a Department of Health and Human Services (HHS) scientific review comparing U.S. policy with approaches used in other developed countries.
The order directs the Centers for Disease Control and Prevention (CDC) and its Advisory Committee on Immunization Practices (ACIP) to evaluate the HHS assessment and determine whether updates to the childhood and adolescent vaccine schedule are warranted.
Any resulting changes would be applied across federal regulations, funding decisions, and coverage policies tied to immunization guidance while maintaining access to vaccines currently available in the United States.
The HHS review examined U.S. immunization recommendations alongside those of peer-developed nations, including vaccination rates, clinical and epidemiological data, public confidence in health agencies, and how countries structure vaccine recommendations and mandates.
The White House said the assessment includes a historical comparison of the CDC childhood vaccine schedule.
According to the summary, children following the CDC schedule in 1980 received 23 doses delivered through seven shots covering seven diseases.
By 2024, that figure had increased to at least 84 doses across 57 shots covering 17 diseases, along with an RSV monoclonal antibody immunization.
The assessment identifies vaccines that are consistently recommended across peer countries and lists 11 routine childhood immunizations as a core set referenced in the review.
The assessment states that additional vaccines may be administered through clinical decision-making between parents and healthcare providers on a case-by-case basis, depending on individual circumstances.
Resist the Mainstream reported earlier this year that the CDC reduced the number of universally recommended childhood vaccines from 18 to 11 under updated guidance.
Vaccines such as influenza, COVID-19, and rotavirus are now handled through individualized recommendations between clinicians and families, while hepatitis A, hepatitis B, meningitis, and dengue fever vaccines are primarily recommended for higher-risk children.
The update reflects a shift toward more individualized guidance between clinicians and families, according to the administration.
HHS Secretary Robert F. Kennedy Jr. said, “After an exhaustive review of the evidence, we are aligning the U.S. childhood vaccine schedule with international consensus while strengthening transparency and informed consent.”
He said the policy emphasizes expanded communication between families and healthcare providers.
The Guardian reported that 15 Democratic-led states have filed suit against HHS and Kennedy over the policy changes, arguing the revisions could affect vaccination guidance and state public health systems.
The lawsuit also challenges changes to respiratory syncytial virus (RSV) recommendations.
Dr. William Schaffner, a professor of medicine at Vanderbilt University and former member of the CDC’s Advisory Committee on Immunization Practices, said, “If we do not progressively vaccinate children from certain diseases, sooner or later we will see the resurgence of these diseases, just as we are seeing with recent outbreaks of measles.”
Federal officials said the CDC and ACIP will review the HHS assessment and determine whether updates to childhood immunization recommendations are warranted following the evaluation process.
