Application Note: Cold chain social value
19 February 2020

In 2016, researchers estimated that vaccines would save $544 billion in illness costs and $1.43 trillion in broader economic benefits in GAVI eligible countries alone. According to these figures, immunization programs have the highest return on investment of any development initiative. To evaluate the inherent social value of a single cold chain unit, two case studies were undertaken, the findings of which are detailed within this white paper. The first case study was conducted by surveying 245 health centers in Kano, Nigeria. The second case study used data on 1,632 solar direct drive (SDD) cold chain equipment from over 5,000 surveys collected across Nigerian healthcare centers.
