I am writing to urge you to demand a full investigation into Secretary Robert F. Kennedy Jr.'s politicization of the CDC and the agency's recent changes to childhood immunization recommendations. These revisions contradict established science and threaten the health of children across our state and nation. In 2025, the CDC released a new childhood immunization schedule that no longer recommends routine 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. Medical experts have condemned this process as fundamentally flawed and dangerous. The timing could not be worse. These recommendations were released during a record-high surge in hospitalizations for flu-like respiratory illnesses. Rather than protecting children during a public health crisis, the CDC is actively undermining their safety by removing evidence-based protections against preventable diseases. The consequences extend beyond immediate health risks. These changes will worsen the ongoing national decline in vaccination rates, reduce access to care by requiring unnecessary doctors' visits to obtain vaccines that should be routinely available, and endanger insurance coverage for vaccines. Families will face new barriers to protecting their children from serious illness and death. I am asking you to take immediate action by demanding a comprehensive investigation into how these changes were made, who was involved in the decision-making process, and what scientific justification exists for contradicting decades of established medical evidence. Children's lives are at stake, and they deserve policy decisions based on rigorous science, not political ideology. Our communities cannot afford to see preventable diseases return because of politically motivated attacks on public health infrastructure. I urge you to stand up for evidence-based medicine and the wellbeing of children.
