Addressing global vaccine adherence

Vaccines save millions of lives every year, yet almost 60% of children in Pakistan never complete their immunization schedule. We worked with Trust for Vaccine & Immunization to develop a wearable reminder band for newborns. The Gates Foundation funded an initial pilot in 2015 in rural Pakistan, and a future trial, funded by 3ie, will test the same VIR band in Nigeria.

We explored and evolved the band's material, form factor, and technology integration through prototypes and user testing sessions. The vaccine reminder band uses a vegetable-based dye that progresses across a window over time, letting the family know when it's time for the next round of vaccinations.
