 ## Overview
 
-The Immunization resource is intended to cover the recording of current and historical administration of vaccines to patients across all healthcare disciplines in all care settings and all regions.  This resource contains the functionality to query a patient's immunization history. Detailed administration records may be found in the [`MedicationAdministration`] resource, while this Immunization resource would represent the known vaccination history regardless of where the administration itself was done.
