Lyngsoe Tracks COVID-19 Vaccines with Passive RFID

Lyngsoe Systems has released a solution to track every COVID-19 vaccine vial from receipt at a clinic to a patient’s arm, using UHF passive RFID sensor-based tags to detect the temperature and liquid level of each vial being stored and then used to administer vaccines to patients, as well as for monitoring expiration data and ensuring vials are not reused.

Additionally, Bluetooth Low Energy (BLE) enables the real-time management of temperatures within a clinic’s coolers and freezers. The solution is intended to automate data collection regarding the administration of vaccines, as well as to help users confirm the temperature of a given vaccine, along with its authenticity and expiration date, and whether it has been properly diluted prior to being administered to a patient.
Customers that will deploy the technology are typically governments and vaccine manufacturers, according to Lyngsoe. The firm developed the solution based on its existing cold supply chain tracking technology, which is used by the fresh food industry. The vaccine-management system it designed includes RFID sensor labels developed and manufactured by Omni-ID, with built-in temperature- and liquid-sensing functionality, using chips and sensing capabilities from Axzon (formerly RFMicron). These sensor-based passive UHF RFID inlays are integrated into a drug company’s printed vaccine labels.
Lyngsoe’s Healthcare Mate workstation comes with its own RFID reader and antenna arrays, while handheld RFID readers can be used to interrogate tags at smaller clinics where the vaccines are stored and injected into patients’ arms. Data is captured and managed via Lyngsoe’s software on an edge server or in the cloud. Finally, Lyngsoe provides BLE beacons that can be installed in coolers and freezers. The beacons transmit real-time data to a BLE gateway in the workstation, which forwards that data to the server.

We believe this is something which has not been seen before,

says Keld Ole Nielsen Refers, Lyngsoe’s director of business development.

We are proud of what is a fairly low-cost solution,

he adds, which is intended to ensure not only that vaccines are properly handled and delivered to patients, but also that data about each injection can be stored in a central database.

We now have the capacity to manufacture [tags and reader stations] in large numbers.

Governments and healthcare providers are tasked this year with an unprecedented challenge: inoculating billions of people with vaccines being manufactured by multiple companies—and each product has its own storage requirements, including temperature levels and expiration dates. Clinicians must administer the vaccines as efficiently as possible, while managing multiple potential challenges, including counterfeit products, expired vaccines or temperature excursions from the acceptable range. Additionally, mistakes can be made during the diluting process. For example, eight German home-care workers were recently injected with five times the intended dose of vaccine because the product had not been diluted with water.
Lyngsoe’s solution is designed to address the issues of tracking and ensuring the safety of vaccines as they are administered, says Christian Meinhardt, the firm’s sales director for retail and logistics, by alerting clinicians if an expiration date is approaching or has passed, as well as when temperature thresholds have been exceeded or other mistakes are being made. Lyngsoe worked with Omni-ID and Axzon to develop the specialized inlay that enables the tracking of each vaccine and all sensor-based conditions.
