Report of the Indonesia Polio Outbreak Response Assessment – December 2024

Overview

This report summarizes the findings of the second Polio Outbreak Response Assessment (OBRA), conducted in Indonesia from 1–7 December 2024. Following the initial detection of circulating vaccine-derived poliovirus type 2 (cVDPV2) in late 2022 and subsequent cases reported throughout 2023–2024, Indonesia conducted a national polio supplementary immunization activity (SIA) using novel oral poliovirus vaccine type 2 (nOPV2). The assessment reviewed both national and subnational outbreak responses, focusing on outbreak response management, surveillance sensitivity, population immunity, advocacy, communication, social mobilization (ACSM), and vaccine management. The report highlights significant progress in case detection and immunization efforts and provides strategic recommendations to further strengthen AFP surveillance, routine immunization, and preparedness for future virus detection.
