Let the vaccine "24 hours +" can not afford to "cold chain"

Recently, the "problem vaccine" case in Shandong continued to ferment, triggering a major discussion on the safety of vaccines. Earlier, some media said that the injection of "problem vaccine" or causing death, a time, "vacuum panic theory" emotional factors in the Internet, WeChat friends circle rapidly expanding.

While the public was panicking, experts rumored that the problem of illegal vaccines in Shandong was in the cold chain rather than the vaccine itself. The vaccine in question was not transported and stored in accordance with the relevant national laws and regulations. It was separated from the constant temperature cold chain of 2 to 8 degrees Celsius, which affected the quality of the vaccine and its use effect. Therefore, the vaccine that lost the “cold chain” and caused over-temperature failure was lost. It is not the same thing as a fake vaccine or a poison vaccine.

The Regulations on the Administration of Vaccine Circulation and Vaccination clearly stipulates that those who engage in vaccine operations must undergo special approval and have professional and technical personnel, professional refrigeration equipment and standardized management systems. This rule highlights the importance of keeping the cold chain in the vaccine. As a pioneer and leader in global cryogenic storage and safety management solutions, Haier Bio has been pioneering innovations in vaccine cold chain monitoring technology and vaccine refrigerator R&D technology, and has explored a new path from vaccine production to storage to vaccination. To ensure that the vaccine does not fall off the "cold chain."

Strive for full-process vaccine cold chain monitoring without dead ends

As biological products, vaccines have to go through a number of distribution, transportation, and storage processes from production to factory inoculation. The biggest hidden dangers of vaccine circulation and storage are fear of "high temperature exposure" and low temperature "freezing". Among them, "high temperature exposure" means that the vaccine storage temperature exceeds 8°C, which can cause fatal damage to the quality and safety of the vaccine.

Both the World Health Organization (WHO) and the National “Regulations for Vaccination Work” stipulate that the entire process of vaccine production from the time it is manufactured to clinical injection to the human body must be in a constant temperature range of 2-8° C. Over-temperature, long-term storage temperature fluctuations and excessive standards are very easy to destroy the structure of the vaccine, causing it to lose its desired effect, and even increase the incidence of side effects.

In order to ensure the stability and antigenicity of the vaccine, let this vaccine not be used, and the cold chain is particularly important. Therefore, Haier has established a three-level vaccine cold chain security system in cities, counties and counties. Among them, Haier assisted in the establishment of a vaccine cold chain safety program, from vaccine production, transportation, storage to inoculation, three levels of provincial and municipal networks, all-weather, the whole process, full coverage, to ensure the safety of each vaccine.
