In November, as soon as Pfizer, Moderna, and AstraZeneca announced promising results from their respective COVID-19 vaccine trials, the public’s attention began to shift from research and development toward distribution.
Urgent and worldwide demand for vaccination creates an immense logistics challenge. Distributors and health-care providers will need to navigate the vaccine cold chain, a specialized, temperature-controlled supply chain hampered by inefficiencies and limited infrastructure.
As leaders work quickly to optimize and reinforce the cold chain, many will turn to the location technology they’ve used to optimize supply chain management for decades.
Article snapshot: The development of COVID-19 vaccines has broken speed records at a time when the world desperately needs rapid solutions. The next global challenge: distributing vaccines effectively through the cold chain.
Minimizing Risk in Real Time
Improving a supply chain often starts with operational visibility. IoT sensors and real-time data analysis tools can be key tools for logistics companies to collect data throughout a product’s manufacturing and distribution. Adding location technology, like a geographic information system (GIS), creates valuable tracking and visualization capabilities.
In the case of the vaccine cold chain, the combination of IoT and GIS could be key to preventing losses. Vaccines degrade quickly and must be kept within a specific temperature range—public health guidelines note that even minor deviations can render a vaccine ineffective.
Approximately 25 percent of shipped vaccines are compromised due to poor temperature management, according to a 2019 report from the International Air Transport Association. The report estimates that temperature-related pharmaceutical damage costs the health-care industry in excess of $34 billion each year.
For the people and economies depending on a COVID-19 prophylaxis, ineffective cold chain management will be especially costly.
These are precisely the kinds of risks that can be minimized with location intelligence and greater supply chain visibility. The concept has been applied to reducing perishable food waste by using IoT sensors to track temperature shifts during shipment. Using smart maps to track a shipment’s location and temperature adds vital environmental context and transparency in a segment of the supply chain where the risk of disruption is high.
Businesses that monitor live data on a GIS-based map are able to react in real time, as FedEx does to manage its fleet of planes. For vaccine distributors, such situational awareness can expose flaws in the cold chain and help prevent spoilage. Supply chain managers might reroute a delivery if the power is out at its planned destination, or alert transporters if temperature inconsistencies are detected in transit.
For many products—and especially the COVID-19 vaccine—the ultimate goal is faster delivery with fewer losses. Location-based visibility will help cold chain distributors achieve this level of efficiency as the world inches closer to the pandemic’s end.
Finding and Filling Critical Gaps
Efficiency is one attribute of successful vaccine distribution; equity is another. The COVID-19 virus can’t be stopped unless the vaccine is broadly administered. But the cold chain, with its specialized equipment and processes, is inherently an inequitable system. It favours high-resource communities with ample transportation options, a consistent power supply, and a trained workforce. Places and populations that lack these amenities must be identified, and steps must be taken to ensure vaccine accessibility—tasks more easily accomplished with smart maps that highlight coverage gaps.
A Digital Twin Illuminates a Moving Target
The Port of Rotterdam has made a name for itself as a supply chain innovator, and its Container 42 project underscores the value of digital twins. Using sensors, real-time data streams, and location technology, these cutting-edge shipping containers provide a nuanced view of goods in transit to help manufacturers, logistics providers, and retailers plan their supply chains more effectively.
With the cold chain in focus for COVID-19 vaccine distribution, supply chain innovations like this take on heightened importance. Learn more about the Container 42 project in this article.
Such maps could take the form of a supply chain digital twin (see above), a virtual copy of the real world that can be used to test a variety of scenarios and enable smarter responses to supply chain conditions.
For example, each of the three vaccines currently up for approval has different storage requirements. The Pfizer vaccine’s temperature range can only be maintained with an ultracold freezer or dry ice. Moderna’s vaccine must be kept frozen, but standard freezer temperatures suffice. AstraZeneca’s can be stored in a standard refrigerator.
With a digital twin, stakeholders can plan their distribution strategies. Some parts of the US, for instance, have pre-ordered from Pfizer but don’t have ultracold storage. Many plan to rely on dry ice—but what if high demand causes a shortage similar to recent runs on PPE supplies, and as a result, dry ice prices rise? If it turns out to be more cost-effective to install an ultracold freezer, planners will need location intelligence to identify the most strategic location within the community.
Alternatively, some places won’t have the option of freezer storage at all, including certain regions of Africa that rely solely on solar-powered refrigerators. Local leaders will need to ensure that these communities have access to an approved vaccine that can be stored safely at warmer temperatures. A digital twin of the cold chain could highlight pathways to equitable distribution in those areas.
A Location-Based Solution for a Location-Based Virus
Just as COVID-19 has spread from place to place, the vaccine must follow geographic pathways to support a global recovery. Unlike the virus, however, the vaccine’s possible routes are limited by the cold chain. Location intelligence is the key to understanding where vaccines need to go and how to get them there.
As public health organizations continue to approve vaccines and the distribution process begins in earnest, location technologies will likely prove themselves an essential tool in supply chain optimization.
