Althea Smart EHR includes a fully automated CDC/ACIP immunization schedule that surfaces due, overdue, and catch-up vaccine alerts at every patient visit, based on the child’s age and vaccination history. Vaccine Information Statement (VIS) documentation is recorded automatically. Bidirectional integration with all 50 state immunization registries (IIS) submits administered vaccines and retrieves prior vaccination histories in real time, no duplicate entry, no manual registry login.
