Technical alalyses of shipping and storage methods of Moderna vaccine of COVID-19
Shipping and storage requirements of Moderna Vaccine of COVID-19
mRNA-1273, more commonly known as the Moderna COVID-19 vaccine, sounds quite likely technology as Pfizer-BioNTech vaccine of COVID-19, but quite different requirements on shipping and storage conditions.
As we had learned from the previous article that the Pfizer-BioNTech vaccine of COVID-19 should be kept at ultracold/ultralow temperatures between −80°C and −60 °C (−112 and −76 °F), which is a big chanllege for hospitals, CDC, clinics, distributors, carriers and all the relevanted objects, especially to the underdeveloped and developing countries due to the high costs of -86℃ Ultracold Temperature Freezers. While quite unlikely as Pfizer-BioNTech vaccine of COVID-19, Moderna COVID-19 vaccine just need to be kept at -20℃ for long-time storage, and its available for 30days in a 2-8℃ medical refrigerator.
Given on that information, some people may think their household fridges are going to be qualified for the vaccine storage job, the fact is they are wrong, using household fridges fro storing Moderna vaccine of COVID-19 is strongly not recommended.
Compared with professional Medical Freezer and Refrigerators, household refrigerators usually lacks of multisensors, advanced temperature controller, digital display, thick enough insulation, alarm system, specialized shelves and temperature recorder etc, let alone remote monitoring and alarm, corrosion proof, safety locks etc functions.
Most importantly, the refrigerating chamber of most of household refrigerators isn't air-cooled, so its temperature uniformity can't be guaranteed, for example, the object placed in the corner could be 8degree while the other object in the centre could be 1degree, and its cooling speed is much lower than professional medical refrigerator, also the underpower compressor can not make sure freezing chamber has enough freezing capacity when its fully loaded, accordingly the vaccines put inside can't get quickly freezing effect.
So what are the professional qualified medical vaccine refrigerators?
How does it facilitate the vaccine storage and distribution?
Take -25℃ freezer DF25-U270 and 2-8℃ medical refrigerator PMR-315L as examples
After learning about the structure and technical desctriptions, now we can make a conclusion that no household freezers can working as specialized -25℃ vaccine freezers.
As we mentioned from the beginning, the Moderna Vaccine of COVID-19 can also be kept at 2-8℃ for 30days
Equipped with these technologies and functions, specialized -25℃ medical freezer and 2-8℃ medical refrigerator helps us let the vaccine storage work scientifical and safe.
Then what is the right way to ship/transit the Moderna vaccine of Coronavirus?
The cold storage truck can be used for shipping from city to city, thats true and clear.
But what if its small quantity, transiting from small town to villages?
The most convenient and economical way would be carrying by a cooler box
With built-in real-time temperature display, the status of the vaccine always under control.
What if you want the vaccines freezing while transiting?
Get a portable -40℃ freezer DF40-PH25
DF40-PH25 adopts Stirling cryogenic technology, efficient refrigeration performance, perfect insulation effect.
It can be powered by DC12V and AC110/220V, completely capable of working at bumpy conditions.
Built-in battery can get the freezer keep runnning for hours even when its unplugged from vehicle power.
Lastly, we want to stress that the shipping and storage of vaccines is a serious matter, these precious vaccines are life saver for human beings, forget about taking a shortcut, lets do it scientifically and rationally! !
