Natural Immunity History
Retrieve the individual's recorded natural immunities — diseases they're assessed as immune to, with notification, lab test, and diagnosis dates.
Requires an `individualIdentifier` from a prior [Identify Individual](/api-reference/air/individual-details/identify-individual) call. If `naturalImmunityIndicator` on that response is `false`, this endpoint returns success with no list field.
For shared response patterns and the full status-code list, see [AIR Integration](/air).
#### Date format
Date fields use **DDMMYYYY** with no separators.
