Immunization has been declared one of the most cost-­effective health intervention from the 20th century. However, there are still 19,4 million un-­vaccinated and under-­vaccinated children in the world. According to WHO/UNICEF (2016), it is estimated that more than 78% of health facilities in low ­and lower-­middle income countries are equipped with cold chain equipment that is either not functional or that uses obsolete technology, potentially exposing vaccines to excessive heat or freezing. Consequently, vaccines may be damaged or lose their potency before even arriving to the immunization session site. If this deterioration is not perceived by the health workers, the person may be vaccinated with an un-­reliable vaccine so the effective immunization won’t be completed. Nomad is a passive refrigerated vaccine carrier designed so the access to proper immunization for the large proportion of the population, only reachable by outreach sessions or mobile teams, is facilitated.
Notions as portability, intuitive functioning and misuse prevention were developed in accordance with the determination of minimizing the intervention during the progress of an immunization session to avoid overwhelmed health workers.
