At present, vaccines developed by different countries are different, easy to provide and difficult to transport. Vaccines present new challenges. The important reason is that different vaccines are stored at different temperatures.
How to store vaccines is a big problem. There is a shortage of glass vials containing vaccines and special glass as raw materials for their manufacture. It is also necessary to ensure that there are enough bottle stoppers, syringes and other packaging devices. A candidate vaccine of Merck needs to be stored in a low-temperature cold room, but this is a serious challenge for countries that lack such equipment or often encounter power outages.
With such advanced technology in the United States, the vaccines produced by the United States need to be stored and transported in a low temperature environment of - 70 ℃, and can only be stored for 15 days in this environment.
As of May 8, 2021, new data from the National Health and Health Commission showed that at present, 300 million doses of vaccine were reported nationwide. On the 7th local time, the World Health Organization announced that the vaccine developed by the Beijing Institute of Biological Products of China Pharmaceutical Group has officially passed the WHO emergency use certification.
The inclusion of Chinese traditional medicine vaccines in the WHO emergency use list will further accelerate the import and vaccination of vaccines. Vaccines are products with high value, high sensitivity and susceptibility to temperature. The storage of vaccine is also the preparation for safe vaccination. If it is not properly stored, it will lead to the reduction of vaccine efficacy, invalidation and even failure to achieve the effect of vaccination, which will seriously endanger life. In order to ensure the effectiveness in the later transportation and storage process, the vaccine has more strict temperature control requirements.
Vaccine storage has also attracted the attention and attention of relevant practitioners. The low-temperature refrigerator controller developed by Shanghai Peaks Measurement and Control Technology Co., Ltd. in cooperation with the needs of vaccine storage at home and abroad can be applied to all kinds of low-temperature refrigerator equipment. It is also applicable to medical refrigerators and medical refrigerated boxes for vaccine storage.
