First of all, how many times has COVID-19 vaccine been preserved in China?
Generally, the storage temperature is 2 ~ 8℃
Corona-VAC, a candidate vaccine in China, is safe and can be stored in a standard refrigerator at 2~8℃.
The COVID-19 vaccine developed by Madena and Pfizer needs deep refrigeration. The storage temperature of modena coronavirus vaccine is-20℃; Pfizer's vaccine can be stored for 6 months in the ultra-low temperature refrigerator at -70℃, for 15 days in the special insulated transport box for dry ice, and for only 5 days in the hospital refrigerator at 2-8℃.
The main component of inactivated vaccine in China is dead virus, which is relatively stable, so the storage temperature is 2~8℃. For inactivated vaccines, 2~8℃ is the industry practice. Such as rabies vaccine, hand-foot-mouth vaccine and hepatitis A vaccine, the storage temperature is 2~8℃.
For example, the adenovirus vector vaccine developed by Academician Chen Wei and the recombinant protein vaccine being developed by Chongqing zhifei are also stored at 2~8℃.
The vaccines developed by Pfizer and Moderna abroad belong to mRNA vaccines, which are essentially genetic vaccines. According to this gene, human cells produce virus S protein and induce human immunity through S protein. MRNA vaccine is not stable at room temperature, so it needs to be stored at low temperature to maintain its stability. If this temperature is not reached, some active ingredients in the vaccine will degrade. abstract
How long can COVID-19 vaccine be kept in the refrigerator?
COVID-19 is also very particular about the vaccination process. Usually, this vaccine needs to be preserved at low temperature, and it is easy to change at room temperature, which affects the vaccination effect. Different vaccines have different requirements for storage temperature, but the storage temperature of COVID-19 vaccines in China is generally 2~8℃, which is relatively stable.
