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

Query parameter
You must include at least one identifier for the patient that's used by the EHR system you're querying. If you don't have a patient identifier, you can find one by searching for a patient with demographics.

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 ascertain 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.
