Does anyone have experience with vaccine passive storage devices in the field? We are piloting the PQS pre-qualified Arktek device in three rural health centers. By design, the device maintains a temperature range between 0°C and 10°C which will not freeze the vaccines so should not pose any risk to the potency of the vaccines. We are seeing some unease from health workers and EPI managers, though, who are concerned that vaccines would be out of the 2°C – 8°C range and at risk of freezing, even though all the evidence shows this type of passive storage device will not freeze vaccines when following proper procedures for conditioning the ice.
On the one hand, this reaction from the health workers speaks to the success of training and insistence on good temperature control between 2 and 8°C. On the other hand, this new technology requires changes to standard operating procedures that have not been fully vetted with stakeholders and still require education and updating.
Has anyone else had experience with this? Any suggestions on how to approach these types of changes to procedures required for this new technology?
I appreciate any thoughts.
