CDC has scheduled a planned outage of the Public Health Information Network Vocabulary Access and Distribution System (PHIN VADS). This planned outage is one step in the process of sunsetting PHIN VADS. We are currently working towards providing a comparable solution for ensuring community members can access value sets after the PHIN VADS sunset. Details related to sunsetting PHIN VADS will be available at a later date.
This planned outage will last 6 weeks, starting Monday, September 29 through Friday, November 7, 2025.
If you need a value set during the outage, please send the name of the value set, object identifier (OID), and any additional information you have to phinvs@cdc.gov (using the subject line �PHIN VADS Outage�). The sooner you can share this information, the sooner our team can assist.
During this reset, existing subscriptions may be canceled. If you would like us to renew your subscription after the reset, please email phinvs@cdc.gov and let us know which subscriptions should be renewed.
