Garvey Automatic Vial Dryer Keeps Vaccines Effective by Reducing Time Out of the Cold Chain
For vaccines to do this essential work, they must retain their effectiveness. This requires vaccines to be kept at the proper temperature from the time they’re manufactured to the time they’re administered. Time spent out of the cold chain causes vaccines to lose potency — a process that’s permanent, irreversible, and all too common. A CDC study found that 23% of vaccination errors reported between 2003 and 2013 were due to storage errors or administering expired vaccines .
In a typical process, vaccines are manufactured and then stored in a refrigerator or freezer. When the vials are ready to be shipped, they’re taken out of the cold chain for inspection and labeling. Just like with a cold beverage on a hot day, when the cold vials are brought to room temperature, condensation forms. This makes visual inspection difficult and interferes with label adhesion.
In most facilities, the current solution is to place the vials in a conditioning room for 24 to 48 hours to allow the condensation to dissipate. Unfortunately, this amount of time out of the cold chain can make the difference between a vaccine that works and one that doesn’t.
