I am writing to demand a full investigation into the CDC's recent unilateral changes to the childhood immunization schedule. These revisions, released in 2025 under Secretary Robert F. Kennedy Jr., contradict established science and threaten the health of children across the country. The new schedule no longer recommends routine childhood vaccination against flu, rotavirus, hepatitis A and B, some types of meningitis, and RSV. These changes were made behind closed doors without formal public comment or rigorous scientific expert input, raising serious questions about their legality. The timing is particularly alarming, as these recommendations were released during a record-high surge in hospitalizations for flu-like respiratory illnesses. The consequences of these changes extend beyond immediate health risks. They will worsen the ongoing national decline in vaccination rates that already endangers community immunity. They will reduce access to care by requiring unnecessary doctors' visits to obtain vaccines that were previously routine. They may also jeopardize insurance coverage for vaccines, creating financial barriers for families. Medical experts have criticized the process by which these changes were implemented. The CDC has been politicized to promote an anti-vaccination agenda rather than following established scientific protocols. This represents a dangerous departure from evidence-based public health policy that has protected generations of American children from preventable diseases. I urge you to demand a comprehensive investigation into how these changes were made, who was involved in the decision-making process, and what scientific evidence was considered. Congress must hold Secretary Kennedy accountable for this attack on childhood vaccination access and ensure that public health policy is based on rigorous science, not ideology. Our children's health depends on your immediate action.
