School nurses verify immunization compliance by hand from paper

Every fall, school nurses in most US states must verify that each enrolled student meets state immunization requirements. In many districts, this means manually reviewing paper immunization cards or faxed records from dozens of different pediatric offices, comparing each date against state-specific requirements, and entering data into a school health system that is not connected to the state IIS. So what? A single school nurse handling 800+ students spends weeks on manual data entry and verification during the busiest time of the school year. So what? Errors are inevitable -- a nurse may misread a date, miscount doses, or fail to flag a student who is actually non-compliant. So what? Non-compliant students slip through and attend school unprotected, or compliant students are incorrectly flagged and their parents receive threatening exclusion notices. So what? Parents who receive false non-compliance notices lose trust in the school health system and become more resistant to future vaccination requirements. Why does this persist? School health information systems are typically separate from state IIS systems, and most lack bidirectional integration. Many states still accept paper CIS forms signed by parents or providers, and schools have no way to verify whether the paper is accurate without calling each provider individually.
