Pfizer COVID-19 vaccine needs to be stored at minus 70 degrees. Is this condition too harsh?

The ultra-low temperature storage conditions of Pfizer COVID-19 vaccine at minus 70 degrees Celsius are really harsh, and such harsh storage conditions may lead to higher transportation and storage costs.

You know, the temperature in the usual freezer is only-18 degrees Celsius, while the temperature in the soft freezer in the hospital is only -7 degrees Celsius. So if Pfizer COVID-19 vaccine really needs to be produced and used in large quantities, then a problem that comes with it is to obtain a large number of ultra-low temperature storage and transportation facilities.

And this may indirectly lead to another problem: increasing the transportation of Pfizer COVID-19 vaccine &; Storage costs, in turn, push up the price of Pfizer's crown vaccine.

1. Pfizer COVID-19 vaccine was stored at minus 70 degrees. 20201October 9th is 165438+. Because it was reported that the vaccination efficiency of Pfizer COVID-19 in the United States was as high as 90%, European and American stock markets rose sharply, but soon, Pfizer revealed that its vaccine needed to be kept at minus 70 degrees.

This unexpected change has gradually calmed the enthusiasm of market investors.

Many netizens began to ask online why Pfizer's COVID-19 vaccine needs to be kept at an ultra-low temperature of minus 70 degrees. What does this mean?

Second, Pfizer's mRNA vaccine has poor thermal stability. Now that Pfizer has publicly admitted that their COVID-19 vaccine needs to be stored at the ultra-low temperature of minus 70 degrees, we can directly understand that Pfizer's mRNA vaccine has poor thermal stability.

MRNA vaccine also belongs to the category of nucleic acid vaccine.

Although the stability of nucleic acid vaccine should be better than that of traditional vaccine in theory, the actual performance of Pfizer COVID-19 vaccine shows a phenomenon contrary to the theory.

Thirdly, the storage conditions of Pfizer COVID-19 vaccine are indeed too harsh. After Pfizer said that its vaccine needed to be stored in an ultra-low temperature environment below -70 degrees Celsius, although the market experienced a disappointment at first, it soon woke up and began to think about how to meet the ultra-low temperature storage conditions of Pfizer vaccines.

Some people suggest that a large number of liquid nitrogen be used for transportation and storage, while others suggest that the US government purchase a large number of ultra-low temperature refrigerators at -70℃. Although American netizens are very talented and have a clear analysis, they still can't avoid a simple fact. What do all ultra-low temperature storage facilities mean? High cost? . ?

Therefore, on the whole, it is undeniable that the storage conditions of Pfizer COVID-19 vaccine are indeed too harsh.
