Sistem Monitoring Imunisasi Logistik secara Elektronik (SMILE)


Sistem Monitoring Imunisasi Logistik secara Elektronik (SMILE) is an innovative technological solution that aims to strengthen the immunization supply chain system in Indonesia – home to a birth cohort of nearly 5 million. It ensures that safe and effective vaccines are available to all children, at all times. SMILE enables real-time visibility of vaccine cold chain logistics by digitizing stock supplies and storage temperature across vaccine cold chain points.

The mobile and web-based application is being implemented by the Ministry of Health and supported by the United Nations Development Programme (UNDP). Currently, SMILE is being piloted in 54 Puskesmas in Kota Bogor, West java, and Kota Tangerang Selatan, Banten.

The goal is to roll out the system across all 34 provinces, strengthening the public health system and acting as a catalyst to achieve the health-related targets of the 2030 Agenda for Sustainable Development – namely those under Sustainable Development Goal 3: Good health and well-being for all at all ages.

What does SMILE do?


The digital innovation consists of a mobile app for the cold chain handlers, a web interface the app feeds data into, a temperature logger that monitors storage temperature of vaccines, and a vaccine and cold chain manager who ensures that the product and processes work seamlessly. Through the analytics on the SMILE web interface health officials can check if vaccines are overstocked, falling short of the prescribed levels or completely stocked out, easing governance and programme management by making data available from even the most remote locations.

SMILE boosts operational efficiencies, brings cost savings for government health providers and addresses inequities in vaccine coverage. It combines state-of-the-art technology, systematic record-keeping practices and a network of trained personnel to support health officials in addressing widespread inequities in vaccine coverage by overcoming constraints of infrastructure, monitoring and management information systems, and human resources, which often result in overstocking and stock-outs of vaccines in storage centres. By making data readily available to policy and decision-makers, it facilitates evidence-based decisions on public health.

Key results

  • All vaccine inventories digitized at 58 cold chain points in West Java and Banten, linking to 2,723 Posyandu and private practices.
  • Over 10,000 transactions per month on SMILE, showing high levels of usage and adoption by Pukesmas staff. Data entry errors have also been reduced by 74%.
  • Vaccine stock-outs have been reduced by 36% and over-stocking by 56%. Vaccine stock wastage has been reduced by more than 90%.
  • Over 100 vaccine handlers and health care workers have been trained on SMILE.
  • 80 temperature loggers installed for remote temperature monitoring of cold chain equipment.
