The CDC does not recommend the transport of vaccines - with good reason. However, there are ways to do it safely in an emergency situation.
Refrigerated and frozen vaccines must maintain their optimal temperature values to preserve their potency. Transporting them only multiplies the opportunities for temperature loss due to the potential of uninsulated packaging, warm storage spaces in transport vehicles, or improper coolant materials. All the more reason that being able to monitor vaccines’ temperature directly inside the container is essential to ensure potency. In this post, we’ll review some of the best practices for proper vaccine transport.
Vaccine Transport Containers and Materials
Proper supplies are essential for the safe transport of vaccines. These should include at a minimum:
Do not use commercially available soft-sided coolers. Most are poorly insulated and likely to be negatively affected by ambient temperatures.
Do not use frozen gel packs or coolant packs from vaccine shipments. Even if they are conditioned or appear to be sweating, they can cause vaccines to freeze.
Emergency Vaccine Packing and Transport
Improper packing for transport is as risky for vaccines as a failed storage unit. To help make sure your vaccines arrive safely, follow these procedures for emergency packing and transport:
Transport of Diluents
Transport diluents with their corresponding vaccines to ensure there are always equal amounts of vaccines and diluents.
Never freeze diluents, not even during transport.
Transport of Varicella-Containing Vaccines
If varicella-containing vaccines must be transported during an emergency, The CDC recommends using both a portable vaccine freezer unit and a temperature monitoring device. You should also be sure to record the following:
Do not use dry ice, even for temporary storage. It might expose the vaccines to temperatures colder than -50° C (-58° F).
Transported varicella-containing vaccines must be used or discarded. Do not put back in the freezer.
The Importance of Wireless Sensors
As the example of varicella-containing vaccines demonstrates, a best practice for transporting ALL vaccines is to use a wireless digital data logger for continuous temperature monitoring.
Our sensors are perfect for monitoring throughout the cold chain. The sensors can be deployed directly inside of trucks or other vehicles across the cold chain to continuously monitor the temperature of vaccines and medications throughout transit. If the temperature of the truck goes out of the recommended range, you will be immediately alerted. Using continuous monitoring devices is an effective way to ensure the safety of your vaccines and medications.
