Rising Measles Cases in North Sumatra: A Looming Public Health Challenge
North Sumatra province is currently facing a concerning rise in measles cases. As of March 4, 2026, health officials have reported 387 suspected cases and confirmed 18 positive cases of measles for the year. While no fatalities have been recorded, the situation highlights a vulnerability in immunization coverage and a potential threat to public health.
The Immunization Gap and Vaccine Supply Issues
Despite an increase in Measles and Rubella (MR) immunization coverage from 80.79% in 2024 to 84.1% in 2025, North Sumatra still falls short of the national target of 93%. A key factor contributing to this shortfall is an inconsistent vaccine supply. According to Novita Rohdearni Saragih, Head of Disease Prevention and Control at the North Sumatra Provincial Health Office, the limited availability of MR vaccines in 2025 – due to prioritization for a broader MR BIAS campaign and insufficient central buffer stocks – hampered immunization efforts at local health centers.
Regional Disparities in Immunization Rates
The impact of these challenges isn’t uniform across the province. While eight districts have met or exceeded the immunization target, significant disparities remain. Deli Serdang leads with an impressive 122.51% coverage, followed by Padang Lawas (100.44%), Humbang Hasundutan (98.34%), Asahan (97.61%), Labuhanbatu (96.74%), Langkat (96.11%), Pakpak Barat (95.27%) and Padang Lawas Utara (94.51%). The remaining 25 districts/cities are lagging behind, creating pockets of vulnerability.
The Importance of a Two-Dose Approach
Health officials emphasize that a single dose of the MR vaccine is insufficient for optimal protection. Novita Rohdearni Saragih explained that the first dose doesn’t fully establish immunity and is not enough to achieve herd immunity. A second dose is crucial, providing up to 95% protection against measles.
Looking Ahead: Strengthening Immunization Programs
The current situation underscores the need for a multi-faceted approach to strengthen immunization programs in North Sumatra. This includes ensuring a consistent and adequate vaccine supply, targeted outreach to communities with low immunization rates, and public awareness campaigns to emphasize the importance of both doses of the MR vaccine. The North Sumatra Provincial Health Office is actively working to address these issues and improve immunization coverage across the region.
