Measles in Indonesia: Vaccination Coverage and Identified Challenges

Measles has re-emerged as a significant public health threat in Indonesia, signaling gaps in immunization coverage and systemic health inequities. Following the disruptions caused by the COVID-19 pandemic, the country has seen a troubling resurgence in cases. This editorial examines the current epidemiological situation, structural barriers to vaccination, and necessary strategies for elimination. In 2025, Indonesia recorded over 63,000 suspected cases, with the trend continuing into 2026. Current vaccination coverage for children aged 12–23 months stands at 73.46%, which is significantly below the 95% threshold required for herd immunity. Key barriers identified include maternal education levels, archipelagic geography, and sociocultural factors such as religious permissibility and safety concerns. Addressing the measles resurgence requires a multi-faceted approach: strengthening routine and catch-up immunization services, addressing social determinants of health, and rebuilding public trust through community engagement. Achieving high coverage is essential to prevent severe clinical complications and protect vulnerable populations.
