Vaccine cold chain monitoring refers to the temperature range at which vaccines must be stored in order to remain effective. This process begins when the vaccine is manufactured and ends when it arrives at its customer's destination.

Our today's topic may not seem easy, but it is essential. Many people and organizations work together to deliver vaccines around the globe using Bio Pharmaceutical Asset Trackers and Data loggеrs. It takes a strong refrigeration systеm to store, manage, and transport these temperature-controlled life-saving vaccines; that's what we're here to discuss!

The COVID-19 pandemic has devastated countries worldwide, but luckily vaccines are being transported to help put an end to it. However, for the process to be effective, the vaccine cold chain needs do its job well too.

Cold chain management of vaccines
Vaccine management requires three key components: vaccine storage temperatures, personnel training and education, and storage and handling planning. Keep reading to learn more about each of these areas.

Vaccine storage temperatures
 
Vaccines are delicate and must be stored at the temperature recommended by the manufacturer to ensure they remain effective. Fluctuations in temperature or faulty storage equipment can lead to spoiled vaccines. 

All vaccines containing varicella must be stored in a frozen environment at temperatures between -58F and +5F. In contrast, all the inactivated vaccines must be deposited in a refrigerator at temperatures between 35F and 46F to ensure full potential of the vaccine.


Storage & handling plans
 
In order to store and handle vaccines properly (in cold chain management), routine plans should be put in place that cover ordering and accepting deliveries, managing inventory, storing and handling vaccines, and dealing with compromised vaccinations.

Every vaccines storage facility should have a comprehensive emergency plan that covers all potential disasters, from power outages to human error. Moreover, the plan must be easy for all staff members to understand and execute quickly in the event of an emergency.
 
Personnel, training & education
A vaccine coordinator should be appointed to manage vaccine cold chains, with at least one backup person to maintain accountability.

The personnel who will be administering the vaccines must be given comprehensive training. They should know about all of the relevant policies and procedures, and stay up-to-date with advancements in their field.
Cold chain maintenance in vaccines
The sectors below must be kept up-to-date at all costs to prevent vaccine cold chain complications.
 
Vaccine storage equipment 
It is essential to regularly check and maintain vaccine storage equipment to ensure it is working correctly. This includes checking refrigerators and freezers, which play a vital role in storing vaccines. Everything from seals to thermometers and ventilation should be double-checked for manufacturer's specifications compliance safety vaccination cold chain management program requirements


A dedicated team should be responsible for daily maintenance of the refrigerators and freezers so that the quality of the vaccines does not deteriorate.

Temperature monitoring
 
It is essential to regularly monitor and maintain the temperature as part of a vaccine cold chain. Temperatures must be checked in both freezers and refrigerators at least twice a day.

It is important to maintain a temperature log so that other staff members can easily keep track of the temperatures and adjust them as needed.

Without a reliable temperature monitoring plan, the vaccine cold chain will undoubtedly be damaged. Make sure you frequently check temperatures and regularly maintain all parts of your Monitoring system to have an effective routine
