Inuwa Barau Ya'u of the National Primary Health Care Development Agency (NPHCDA) in Nigeria will use bracelets of different colors to symbolize the order of the five routine childhood vaccinations to remind families with limited education when to get their children immunized. Bracelets are low cost and easy to see on an infant, and are a common adornment in many cultures, including the Fulani tribe found in remote areas in Northern Nigeria. Vaccination coverage is low across Nigeria, with vaccine-preventable diseases still accounting for over 20% of infant mortality.

Drew Arenth, Benjamin Fels, and Suvrit Sra of Macro-Eyes in the U.S. are applying a statistical machine learning approach to the immunization supply chains of health facilities in Tanzania that accurately and continuously predicts demand to ensure the right vaccines and levels are being stocked. Currently, vaccine supply is largely fixed or driven by depleted stocks. This leaves children unable to be vaccinated due to stock outs at clinics, as well as often high levels of waste, which could both be overcome by better forecasting vaccination needs for individual clinics.
