    required

This table has notes about how to use parameters for this API action specifically, but it's not exhaustive. Refer to the Immunization schema for more details.

Query parameter
Required
Notes
patient.identifier
Y
You must include at least one identifier for the patient that the EHR system uses. If you don't have a patient identifier, search for a patient with demographics to find one.

The response contains one or more vaccinations for an individual patient. You can find the total number of included vaccinations in the total array for FHIR® responses.

We recommend that you check the StatusReason field to find out whether a vaccination was administered. If populated, it should contain a reason for not administering a vaccination. If the field is empty, it’s likely that the vaccination was successfully administered.
