United States modifies federal childhood vaccination recommendations

The United States government has implemented a major overhaul of federal childhood vaccination recommendations through a new executive order. The policy reorganizes immunizations into three distinct categories: those recommended routinely for all children, those targeted at specific risk groups, and those subject to individual medical assessment and parental consultation.

Under this new framework, the number of diseases for which universal childhood vaccination is recommended has been reduced from 18 to 11. While vaccines for measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, varicella, and pneumococcal disease remain in the general recommendation group, others—including those for hepatitis A and B, influenza, and COVID-19—may now depend on age, risk factors, and clinical evaluation.

The Department of Health and Human Services (HHS) has opened a public consultation period, ending September 20, 2026, to gather input from parents and healthcare professionals regarding these categories. Additionally, the executive order directs the Justice Department to support legal challenges involving state-level vaccine requirements and exemptions.
