I am really interested in the potential benefits that blockchain technology could bring to immunization. There have been many discussions on vaccine packaging and barcoding as I can recall, and I was wondering if blockchain technology was mentioned (or even central now!) during those discussions, and also if some of you would have some stories to share about using this technology at all.
It seems from several sources, including the World Bank that blockchain technology can provide a cost-effectiev solution to many challenges encountered by government-led supply chains, such as maintaining vaccine quality throughout the supply chain or ensuring vaccine availability at service delivery points.
In addition to that, by allowing to track vaccines from lab to patient, particularly where a network of various players in different geographies are involved, blockchain technology would then aid to prevent fraudulent products entering the supply chain and bring down the risk that ineffective counterfeited products represent for public health. That could be quite an interesting opportunity, especially since the WHO estimated that countries are spending about $30bn on counterfeit drugs, that cases of counterfeited yellow fever and MenA vaccines were reported and that WHO thinks most cases of fake medicines re likely to be unreported (see this article).
I'd love to hear from immunization on what their thoughts, hopes and possibly criticisms would be!
Thanks all and have a great day!
