These use cases do not make any assumptions about the setting in which care is being delivered (e.g. primary care physician’s office, mobile immunization clinic, hospital, etc.).  Although some references to software applications are specific, the preferred candidate standards should, where possible, support and enable the delivery of care in any setting, and the viewing or recording of immunization data on different hardware devices.
