Reporting Systems

Enrollment in the State Immunization Information System (IIS) or California Immunization Registry (CAIR) is a condition of participation in the state’s COVID – 19 vaccine programs. In addition, facilities administering COVID – 19 vaccine will be required to document COVID – 19 vaccines in PrepMod.

 Enroll in CAIR

Those who require CAIR enrollment:

  • Instructions for Enrolling in CAIR
  • Some facilities may already be enrolled in CAIR; organizations that are uncertain of their enrollment status should contact their Local CAIR Representative or the CAIR Help Desk, both of which are noted on the CAIR enrollment webpage.
    • Please see attached specific instructions for enrolling in CAIR; it is important to follow the instructions to prevent substantial delays in CAIR access approval. If your facility accidentally submitted an application for regular CAIR access or if you requested CAIR user accounts, please follow up with your Local CAIR Representative to indicate your plans to use PrepMod.
    • If your COVIDReadi registration is pending, please check your storage and temperature device If this is a barrier to your registration, there are many relatively inexpensive options available on shopping platforms that can be delivered quickly. You can update the details in your registration immediately before unit arrival
