SSAAI In Person Meeting Summary

This meeting summary report from the SSAAI Summit, held September 18–19, 2025 in Chicago, synthesizes findings from 40 participating health systems on the current state of immunization data capture, exchange, and clinical decision support. Across three domains, a consistent picture emerges: technology is maturing, but systemic gaps persist. On the documentation side, tools like EHR “dot phrases” and Best Practice Advisories — which require clinicians to acknowledge a patient’s vaccination status before closing an encounter — have shown meaningful results, with participating sites reporting dramatic increases in provider utilization of these tools and a direct correlation between their use and increased vaccine administrations. On data exchange, bidirectional connectivity between health systems and state immunization registries remains hampered by manual reconciliation requirements, data latency of up to a week, and near-total absence of cross-state record sharing. On clinical decision support, the report finds that alert fatigue is a real barrier, and that the most effective tools are brief, actionable, diagnosis-specific, and embedded in existing workflows. The report concludes with a call for national data standards and a strategic roadmap to be developed through forthcoming Data and Technology Innovation Roundtables.
