# Fetch a vaccine historical treatment

> Fetches a vaccine historical treatment by its ID.

A **vaccine historical treatment** represents a vaccination that was recorded from the clinic patient's history (e.g., imported from a previous clinic or manually entered) rather than administered during a visit. These records help maintain a complete vaccination history for the clinic patient.
