Across the 38 provinces of Indonesia, a quiet but critical gap is emerging between official health reports and the reality of vaccine access on the ground. While the nation has aggressively expanded its healthcare reach, recent data reveals that nearly half of the country’s youngest children are missing essential life-saving protections.
A comprehensive 2025 survey supported by the World Health Organization (WHO) found that only 56.4% of children aged 12–23 months were fully immunized. This figure underscores a systemic struggle to maintain consistent coverage, particularly as the government works toward strengthening immunization evidence and strategy in Indonesia to prevent future outbreaks of vaccine-preventable diseases.
The disparity is not merely national but deeply regional. In North Sulawesi, immunization coverage exceeds 95%, reflecting a high-functioning local health infrastructure. Conversely, in Aceh, that number plummets to just 3.6%. These striking contradictions suggest that geography, local perception, and logistical failures are creating “hidden gaps” that leave entire communities vulnerable.
The challenge is compounded by a breakdown in maternal health protections. Tetanus toxoid coverage among women has seen a sharp decline; while the first dose remains above 70%, the critical fifth dose—essential for long-term immunity—falls to under 20%.
The Digital Divide in Public Health
For health authorities, the primary obstacle is often not a lack of vaccines, but a lack of reliable information. There has been a persistent inconsistency between administrative reports—which often paint a rosier picture—and population-based surveys that reveal the actual gaps in coverage.
Central to this issue is the performance of the Electronic Immunization Registry and the SatuSehat application. While designed to modernize tracking, these digital tools are currently undermined by poor data quality. A recent Data Quality Assessment revealed that the systems used by health workers to record childhood immunizations, vaccine supplies, and cold chain logistics are struggling with accuracy and timeliness.
| Metric | Performance Rate |
|---|---|
| Data Uniqueness | 79% |
| Date Recording Accuracy | 43.9% |
| Reporting Timeliness | 14.6% |
| Vaccine Stock Completeness | 32% |
With only 14.6% of reports being submitted on time and vaccine stock reporting completeness at a dismal 32%, health officials are often operating in the dark. This lack of real-time visibility makes it nearly impossible to identify which remote villages are running low on supplies or which demographics are falling through the cracks.
Turning Evidence Into Intervention
Despite these hurdles, the Indonesian Ministry of Health is beginning to use this raw evidence to pivot its strategy. Rather than applying a one-size-fits-all approach, authorities are now prioritizing provinces with the lowest coverage and tailoring interventions based on the specific barriers found in the survey.
In Banten Province, for example, the data was used to overhaul logistics planning. By fixing the reporting delays that previously led to “vaccine stock outs”—where clinics appear to have supplies on paper but have empty refrigerators in reality—the province is working to ensure that a child’s visit to a clinic does not conclude in a wasted trip.
The survey also highlighted that vaccine uptake is not solely a matter of supply. Factors such as the ownership of vaccination cards, personal perceptions of vaccine safety, and the level of support from family and community leaders play a decisive role. The government is now increasing the involvement of community leaders in public communication to rebuild trust and encourage schedule completion.
A Five-Year Roadmap for Resilience
To synchronize these efforts, the Ministry of Health, in collaboration with WHO, UNICEF, and UNDP, has launched the National Immunization Strategy 2025-2029. This five-year blueprint moves beyond simple delivery, focusing on four critical pillars: expanding service delivery, introducing new vaccines, strengthening disease surveillance, and optimizing supply chain management.
A newly formed Immunization Technical Working Group now serves as the central hub for these partners, tracking progress and responding to emerging challenges in real-time. This coordinated approach is supported by the Australian Government and GAVI, the Vaccine Alliance, ensuring that the financial and technical resources are aligned with the most urgent needs.
The goal is to move toward a system where data—not guesswork—dictates where the next shipment of vaccines goes. By improving the accuracy of the Electronic Immunization Registry and expanding demographic analysis, Indonesia aims to close the gap between its urban centers and its most marginalized remote communities.

The next phase of the National Immunization Strategy will involve a series of province-level reviews to assess the impact of the updated logistics planning in Banten and other priority areas. These evaluations will determine if the shift toward evidence-based resource allocation is successfully raising the 56.4% baseline.
