CDC Vaccination Data Largely Frozen Ahead of RFK Jr. HHS Nomination
A study in the Annals of Internal Medicine found that about half of the CDC databases updated monthly in early 2025 were not updated by Oct 2025, with 38 outdated databases, 33 of them containing vaccination data. By December only one had any updates, prompting concerns that paused vaccination surveillance could hinder outbreak response and targeted outreach. The piece ties the pauses to RFK Jr.’s anti-vaccine stance, while a DHHS spokesperson calls the changes routine data-management decisions.
