Suggest the effective rabies duration (1 vs 3 years) for a dose at point-of-care.

Suggested duration of immunity for a rabies vaccination at point-of-care. Duration is a property of the administration, not the product: a first/primary rabies dose is recognized for 1 year even with a 3-year-labeled product; boosters get the product's labeled duration. See ITE-162. Legacy shape — superseded by NextDoseSuggestionDto, which generalizes this to any vaccine schedule; the rabies endpoint now delegates to the same stage-resolution logic.
