New Requirement to Submit Immunization Data to a California Registry 

AB 1797, a new California bill effective January 1, 2023, requires providers to enter immunizations they administer as well as a patient's race and ethnicity into a California immunization registry (CAIR or RIDE/Healthy Futures). Please see "Enroll in CAIR2" below to enroll today. For additional information, see the AB 1797 Immunization Registry FAQs.

The School and Childcare Roster Lookup (SCRL)
is now available!

An invitation to register was sent to authorized CAIR2 School Users on 10/25/22. This new application quickly returns the immunization status for each child on your roster found in the California Immunization Registry (CAIR), using pre-K or K–12 immunization requirements. You can easily see which children are up to date or behind on their immunizations.
