The decision follows over a year with no virus detected after nationwide campaigns that boosted routine coverage.
Overview
- WHO announced the closure of Indonesia’s type 2 poliovirus outbreak on November 19, citing no detections since June 2024, with the last case reported on June 27, 2024, in South Papua.
- Authorities administered nearly 60 million additional polio vaccine doses, conducting multiple rounds of novel oral polio vaccine type 2 (nOPV2) campaigns.
- Routine immunization strengthened during the response, with second‑dose IPV coverage rising from 63% in 2023 to 73% in 2024 and a new hexavalent vaccine rolled out in selected provinces in October 2025.
- The outbreak began in Aceh in October 2022 and spread to Banten, West Java, Central Java, East Java, North Maluku, Central Papua, Highland Papua and South Papua before transmission was halted.
