San Diego Immunization Registry

The San Diego Immunization Registry (SDIR) is a collaborative effort of the County of San Diego Health and Human Services Agency Public Health Services Immunization Branch and other public and private health care providers, schools, child care providers and other county programs. The Registry provides an electronic record of all immunizations given to an individual by participating providers in both the public and private sectors. It is a secure web-based tool that helps doctors with their immunization practice management. The Registry increases patient satisfaction by decreasing unnecessary immunizations and decreases vaccine preventable diseases by identifying immunizations that are needed.



The County of San Diego Immunization Unit is leading an effort to migrate the existing San Diego Immunization Registry (SDIR) to the California Immunization Registry (CAIR2) system. Please see the Public Health Officer announcement on the SDIR transition to CAIR2 and Questions and Answers Handout to learn more.
