Washington Post The Trump administration took unprecedented steps to recommend fewer vaccines for children without extensive consultations with career scientists.

Vaccine experts at the Centers for Disease Control and Prevention were blindsided by a top deputy toHealth Secretary Robert F. Kennedy Jr.’s decision to unilaterally overhaul the childhood immunization schedule, according to current and former agency staff.

U.S. health officials took the unprecedented action Monday to narrow the list of vaccines that the federal government routinely recommends for all children, a shift that leading public health experts and medical organizations warned could weaken protections against preventable deadly diseases.
