An audit of U.S. Centers for Disease Control and Prevention (CDC) public databases found that nearly half of routinely updated federal health surveillance systems had stopped or delayed updates in 2025, raising concerns that gaps in data, particularly on vaccinations and respiratory diseases, could undermine clinical guidance, public health policy, and public trust.
The findings are published in Annals
of Internal Medicine.
Researchers from Vanderbilt University, University of North
Carolina, Chapel Hill, and Boston University School of Law aimed to identify
which CDC databases had unexplained pauses in updates and evaluate how common
such pauses were among frequently updated CDC databases.
They reviewed the CDC's public data catalog in October 2025,
examining more than 1,300 listed databases and focusing on those that had
previously been updated at least monthly.
Using each database's stated update schedule, they
classified whether updates were current or paused. Of the 82 databases that met
inclusion criteria, 46% had halted updates, most for more than six months. The
majority of paused databases tracked vaccination-related information, while
others covered respiratory diseases and drug overdose deaths.
