“…Of note, while some older studies in our review indicated that vaccination data tracking was a challenge in rural areas, more recently, there have been marked improvements in centralized immunization information systems (IIS). Indeed, 49 states maintain IIS and almost all states report that 80% or more of children have at least two immunizations on record ( CDC, 2020 , Murthy et al, 2017 , Scharf et al, 2021 ). Since some alternative vaccination patterns indicative of parental hesitancy are readily identifiable in such electronic immunization records ( Hargreaves et al, 2020 , Robison et al, 2012 ), moving forward, state IIS data may serve as a rich resource for tracking childhood undervaccination due to parental hesitancy across multiple geographies ( Mbaeyi et al, 2020 , National Vaccine Advisory Committee, 2015 , Newcomer et al, 2021 ).…”

“…3 Disparate IIS operations and legal frameworks can translate into variability in technical and programmatic capacity. 4,5 While progress has been made in strengthening and expanding IIS, further action is needed to help realize the full value IIS can provide in supporting vaccination across the life-course. 6 A critical component needed to identify opportunities for strengthening IIS is understanding the current legal landscape of IIS laws across the country.…”

Background: Immunization information systems (IIS) are confidential, population-based computerized databases that record vaccination doses administered to persons residing within a given geopolitical area. They play a pivotal role in achieving equitable and high vaccine uptake. In the United States (US), they are implemented and managed at the state and local level, creating variability in IIS policies. Methods: We conducted a legal assessment of relevant IIS statutes and administrative codes across all 50 states, the District of Columbia, Philadelphia, and New York City. Where relevant, laws were cross-checked or supplemented with state and local health department resources. Comparisons to previous legal studies were used to evaluate trends in IIS laws over time. Results: The compilation of these laws provides an updated overview of the diverse inter- and intra-state policies within the US that govern the capabilities and implementation of IIS. The findings of this study show that while progress has been made in improving the policies to enable and enhance IIS, gaps in IIS data collection, limited interoperability with local and national health information systems, and inconsistent access to IIS to view or utilize records, limits the full potential of IIS. Conclusions: Findings from this study help shine a light on the evolution of IIS policy over the last two decades, serve as a comprehensive benchmark for future analyses, and may help policy stakeholders who are exploring amending jurisdictional IIS laws.

“…IIS are used to keep individuals on the Advisory Committee on Immunization Practices (ACIP)–recommended immunization schedules by storing immunization records, validating immunization histories, and producing reminder and recall notices. Although the function and use of IIS are similar across all jurisdictions, mandates requiring specific entities to report immunizations to the IIS may differ 2,3. In general, use of Iowa's Immunization Registry Information System (IRIS) is optional, with the exception of providers for the Vaccines for Children and COVID-19 vaccine programs and pharmacies.…”

Data cleansing practices aimed to improve data quality in immunization information systems (IIS) continue to be identified and evaluated by immunization programs to generate accurate and reliable immunization coverage rates. The Iowa Immunization Program has implemented several automated, daily data cleansing practices to improve the quality of records in Iowa's Immunization Registry Information System (IRIS), including the process of sealing records of deceased individuals through vital records matching. This process removes deceased individual records from the active IIS population, which helps reduce denominator inflation and improve the accuracy of immunization rate calculations. Other benefits to this process include decreasing record fragmentation, increasing completeness and accuracy of IIS data, improving reminder/recall functionality, and supporting better clinical decision-making for providers. This process is one of multiple practices implemented in IIS to improve data quality and is limited by several factors, including the inability to capture deaths for out-of-state records.
