The Vaccine Exists. So Why Are Children Still Dying from Measles?

69 deaths from measles in 2025. Four deaths in the first two months of 2026. In a country where the measles vaccine is free and has been available for decades. Indonesia is now the country with the second highest number of measles cases in the world, after Yemen, a country currently at war. Most of the victims are infants under one year old. Children who never had a choice.

This is not a failure of the vaccine. This is a failure of communication.

The vaccine exists. The program is free. Health workers are ready. But out there, millions of parents go to sleep each night after encountering content claiming that vaccines cause autism, contain microchips, or are part of a pharmaceutical business agenda. These messages are packaged neatly, emotionally powerful, and amplified by algorithms. Meanwhile, official messages from authorities or public health institutions often feel like announcements rather than messages meant for people. When these two narratives compete, we already know which one will resonate more strongly at the grassroots level.

Sometimes, there are mothers who want their children vaccinated but cannot voice that decision within their own households. There are families who trust religious leaders in their communities more than doctors at local health clinics, not because they reject science, but because those leaders are present, familiar, and trusted in their daily lives.

A 2024 Gender Analysis report conducted by UNICEF Indonesia, the UNICEF East Asia Pacific Regional Office, and Indonesia’s Ministry of Health found that gender inequality, social norms, misinformation, and power imbalances within households prevent many caregivers, especially women, from accessing immunization services. This important context cannot be ignored when designing communication strategies.

In Indonesia, the messages that have proven most effective are often delivered through methods that sound simple. For example, a posyandu cadre saying directly, “Two children in the neighboring neighborhood were hospitalized because of measles, while the 50 children who received immunizations here are all healthy,” can be more powerful than a thousand campaign posters, mainstream media placements, or official statements from public officials.

An ustadz delivering a message during a religious gathering that the Indonesian Ulema Council (MUI) encourages immunization to protect human life can reach audiences who would never read an official release from the Ministry of Health. A posyandu that adjusts its opening hours to accommodate mothers’ schedules is empathy embedded in a system, not merely good intentions.

The pattern is clear. The right message, delivered by a trusted messenger, in a relevant context.

The communications industry understands very well how trust is built. We know that the same message can be accepted or rejected depending on who delivers it and in what context. This measles crisis is a reminder that poor communication has very real consequences, and that effective communication, which truly listens and respects cultural and social contexts, can save lives.
