Vaccine traceability in Indonesia from primary packaging to consumer BioTracking, from primary packaging to consumer (following the blue arrow in Fig. 4), is a logistics system for vaccines requiring login access and used by distribution staff receiving vaccines from the manufacturer to the point of vaccination to verify and authenticate the product received, logging the receipt and release of products from each distribution unit. BioDetect, which does not require login access, is a downloadable mobile application used by the general public to enable verification of the authenticity of the product and the status of product use at time of vaccination, allowing feedback from the consumer to point of manufacturer (following the green arrow in Fig. 4).
