How do they make sure vaccines stay cold?


IOT Vaccine Storage Temperature Monitoring System manufactured by DECA.

One of the more important logistical aspects of the COVID 19 vaccine rollout is the fact that the vaccines are shipped frozen and have to be kept cold until they are administered. Cold-chain pharmaceuticals have specific temperature maintenance and transportation requirements. Given the vital nature of these materials a monitoring system is vital! When medical facilities are as busy as they currently are, a pharmaceutical, cold storage system offers the following benefits:

  • accurate temperature monitoring

  • alert and notification mechanism to highlight any temperature fluctuations

  • ability to be installed in a different refrigeration and freezer systems

Vaccine Storage Temperature Monitoring System

Just before the pandemic started, DECA manufactured a vaccine storage temperature monitoring system specifically for use in safely storing vaccines at scale in pharmaceutical and laboratory cold storage equipment (refrigerators). Our product consisted of a wire harness that handled both power and data, a PC board, and wifi transmitter. This integrated system serves as the base for an IOT remote temperature monitoring system. It is used in the cold-storage environments where vaccines, pharmaceuticals, biologics, and other sensitive samples and medicines are stored. The system is scalable to include many refrigerator and freezer units and will also warn staff when temperature changes or equipment failures occur. Constant monitoring is crucial not only to ensure these materials are viable but also provide a warning should they need to be moved and/or rescued.


IOT Monitoring Supports Staff and Efficiency

When hospitals are dealing staff shortages or high-volume activity due to health emergencies like the pandemic an IOT/centralized monitoring system assures a high level of efficiency because staff don’t have to check units individually by going to each refrigerator or freezer; staff can check multiple units at a single interface point. An IOT- based monitoring system will also limit staff interaction with surfaces in the work environment.


Logistics of Vaccine Transportation and Storage

Monitoring storage temperatures of pharmaceutical material becomes even more relevant when one considers that the first vaccine approved, by Pfizer needed to be transported at ultra-cold temperatures, -94F! If it thaws and warms up enough. If it warms up it will not be viable. While the Moderna vaccine is also shipped frozen and needs to be kept between -58 and -5, this is more in range with other common vaccines such as Varicella and MMRC. Once any of these vaccines are thawed, they still need to be kept cold, most require temperatures of between +35.6F and -+46.4F.
