    Temperature Control Is Key to Vaccine Storage

    Is your pharmacy's refrigerator maintaining the right temperature?

    As more pharmacists administer vaccinations to their customers, proper management of vaccine inventories is worth reviewing. Drug Topics spoke with Jerilin Kenney, Vice President/General Manager of Life Sciences and Healthcare at Phononic about its line of Evolve refrigerators that provide the reliable temperature control for these high-value products.

    DT: Why is maintaining vaccines at optimal temperature potentially a challenge for pharmacists?

    Jerelin KenneyJerelin KenneyKenney: The typical refrigeration unit has to operate at freezing temperature in order to provide the control temperature needed inside the chamber. There’s a risk it could go into overdrive, thereby freezing the contents inside. The challenge with vaccines is you don’t know if they’ve been frozen or not. All you can do is monitor the temperature to make sure they stay within range.

    DT: Why can’t a traditional refrigerator meet those temperature requirements?

    Kenney: It can, but consumer-grade refrigerators are built for energy conservation. They allow an internal temperature range fluctuation of up to 10 to 12 degrees. The center area of the refrigerator may stay within a nice range, but the extreme areas— the bottom or top of the refrigerator—could extend to very extreme temperature conditions. It is not equipped to provide the uniformity, stability, and lack of freezing conditions that most medical-grade or high-performance refrigerators are purpose-built Evolve Protect Plusto overcome.

    DT: How do Evolve refrigerators address vaccination storage requirements?

    Kenney: Evolve refrigerators do not freeze, eliminating the risk of a product freezing. In the Evolve 5.5 Protect Plus, we built a dual redundant refrigeration system. In the event of a system failure, our system has a dual backup that the Evolve 5.5 can maintain and protect the vaccine. We also built in a monitoring system. Reports can be downloaded through USB or by connecting to a remote server for real time notices of temperature extremes, door opening conditions, or power outages that could put products at risk. These concepts are integrated from the ground up to provide a holistic approach to a better storage environment.

    DT:  Can pharmacists store other medications that need refrigeration in these refrigerators?

    Kenney: Absolutely! Temperature control in the Evolve refrigerators allows a set point anywhere between 2 and 8 degrees Celsius. Our solid-state refrigeration technology precisely hits that target temperature and holds it throughout the entire chamber with no more than one degree of variability from any point in the fridge. That’s not an average temperature — it’s a consistently held temperature. Unlike a normal refrigerator that goes through compressor cycles that go up and down as the compressor turns on and off, Evolve sets a temperature and holds it consistently.
