The [ImmunizationEvaluation](/content/docs/api/fhir/resources/immunizationevaluation/index.html) resource is intended to cover communicating the results of an evaluation of a vaccine administration event against a set of published recommendations. Evaluating administered doses in a patient's immunization history is central to ensuring that the patient is fully protected against vaccine-preventable diseases.
