Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
COVID-19 vaccination uptake has been suboptimal, even in high-risk populations. This paper describes work to extend the Bulk Fast Healthcare Interoperability Resource (FHIR) standard for use in querying state Immunization Information Systems (IIS). We also describe a population vaccination outreach tool that uses both Bulk FHIR and automated single queries to access IIS data. Bulk FHIR protocols needed to be extended to support IIS’s responses for care outside an institution resulting in the addition of Group and Master Data Management FHIR profile functionalities to Bulk FHIR queries to support more accurate and easier retrieval of data. While real-world testing of Bulk FHIR queries using the vaccination outreach system was not possible, we tested an automated-single-query tool in a focused effort to reach 1500 high-risk patients. Results confirmed the potential for performance problems during periods of high demand that could be resolved by Bulk FHIR’s asynchronous retrieval methods.
