Serialization Systems: Advancing Pharmaceutical Equity and Pandemic Preparedness in Global Healthcare

Abstract

The COVID-19 outbreak demonstrated the existence of fatal weaknesses in world pharmaceutical supply chains, unveiled the existence of far-reaching disparities in medicine and vaccine distribution between developed and developing countries. Serialization systems-technological tools that unite pharmaceutical products with distinctive identifiers become central in the way to mitigate healthcare disparities to improve pandemic preparedness. This pandemic revealed that the disjointed distribution channels, vaccine nationalism, and insufficient tracking infrastructure systematically marginalized vulnerable groups, leaving gaps in vaccination coverage that were sustained across pivotal periods of disease spread. There was the development of counterfeited pharmaceuticals during the crisis, which was especially high in areas where regulation was poor, leading to preventable deaths and eroding confidence in healthcare systems. The integration of blockchain technology, the Internet of Things, and digital health platforms presents promising opportunities to improve pharmaceutical traceability, and the pilot implementations of the technologies result in significant decreases in the rate of counterfeit drug penetration and the effectiveness of the supply chain. But there are serious obstacles to the implementation of serialization in resource-constrained environments, such as poor infrastructure, prohibitive costs of implementation, and large digital divides that threaten to contribute to any existing health inequities. Smaller pharmaceutical companies have a greater challenge than larger multinational corporations, which begs the question of how this may affect the affordability and accessibility of medicine in the low income markets. Implementing strategic plans should be done with attention to the accessibility, interoperability, and capacity building to ensure that serialization systems do not advance equity purposes, but instead, strengthen the gaps. The mechanisms of international cooperation, collaboration between the government and industry, and technological transfer can be critical in creating the infrastructure of a sustainable serialization that will be able to provide the routine distribution of pharmaceutical products and react quickly to an emergency situation in the future.
