TL;DR
Senior CDC vaccine experts say they were caught off guard after a top deputy to Health Secretary Robert F. Kennedy Jr. moved to narrow the federal routine childhood immunization schedule. Public health groups warn the change, described by officials as unprecedented, could reduce protections against vaccine-preventable diseases.
What happened
According to reporting cited by the source, a senior deputy to Health Secretary Robert F. Kennedy Jr. took unilateral action to alter the federal childhood immunization schedule, narrowing the list of vaccines the government routinely recommends for children. Staff at the Centers for Disease Control and Prevention told reporters they were not forewarned and described themselves as 'blindsided' by the decision. The change was characterized in the reporting as an unprecedented step by the administration and prompted immediate concern from public health experts and medical organizations. Those groups warned that scaling back routine recommendations could weaken population-level protections against diseases that vaccines can prevent. The reporting does not list which specific vaccines were removed or modified in the schedule.
