Trump narrows childhood vaccine recommendations and urges splitting the MMR shot
Executive Order 14420 recognizes a narrower federal core childhood-vaccine framework, listing immunizations for 11 diseases as recommended for all children and moving several others into risk-based or shared-decision categories. The order also calls for separate measles, mumps and rubella shots once such single-disease products are domestically available. The policy change is confirmed; the evidence reviewed here still does not show a health or safety benefit from splitting MMR, and the broader vaccine-autism causal claim remains unsupported by the systematic evidence reviewed by WHO and by CDC’s MMR-specific safety review.
