  • Access to consolidated immunizations records for children.
  • Forecasting of immunization doses needed by an individual, based on the CDC approved schedule as indicated by the Arizona Recommended Childhood Immunization Schedule.
  • Production of an official Immunization Record for patients to be used by schools or daycare centers.
  • Inventory tracking and management of vaccine supplies.
  • Generation of immunization reports such as the Vaccines For Children (VFC) report and a list of children who need to be reminded or recalled.
  • Clinic assessment through Clinic Assessment Software Application (CASA).
  • Ability to interface with various patient management or billing systems.
  • Introduction of new vaccines or changes in the vaccine schedule. Generation of coverage reports for managed care (e.g., HEDIS) and other organizations.


  • Protection from childhood diseases.
  • Reduction in duplicate/unnecessary immunizations.
  • Increased chance of a Healthy lifestyle for children.
  • Access to one consolidated record of all immunizations a child has received.
