Vaccines are about to be put on the market. What challenges will the cold chain monitoring system face in the future?
On December 19, the State Council's joint prevention and control mechanism held a press conference to announce that key populations will be vaccinated nationwide. On the evening of December 20, Tao Lina, a former vaccine physician of the Shanghai Centers for Disease Control and Prevention, told the Health Times that according to industry news, my country’s first batch of new crown vaccines is expected to be vaccinated 50 million times, and the first dose will be completed on January 15. The second stitch was completed on February 15. The details are still subject to the official release.

Since the official announcement of Pfizer Vaccines in the United States on November 19 that it will be put into use on a large scale, some netizens are very anxious because the results of the third phase of the domestic vaccine have not been announced. Fortunately, it was announced that the domestic vaccine will be launched. Putting into use message. Regarding the 'long overdue' of Chinese vaccines, some netizens are wondering why domestic vaccines will be on the market a full month later than American vaccines?

In fact, the reason for the late launch of domestic vaccines can be described in one sentence: success and failure are also failures. The domestic epidemic situation in my country has been controlled so well. There have been no local cases for a long time. This has brought about the problem of not being able to find enough volunteers to test the vaccine. Therefore, China’s vaccines are all tested abroad. Overall planning and deployment has caused my country's vaccine progress to lag slightly behind that of other developed countries.

Cold chain monitoring system and cold chain logistics

Modern cold chain logistics are temperature-controlled logistics. In order to assist cold chain transportation companies in achieving better temperature control, cold chain temperature monitoring systems can be used.

The cold chain monitoring system can ensure that the cold chain transportation meets national standards, and the temperature and humidity remain unchanged throughout the process. Monitor the temperature at any time by using the embedded temperature and humidity recorder, and upload it to the supervision cloud platform through the monitoring terminal for real-time monitoring.

Monitoring terminal: Embedded temperature and humidity recorder (4G type)
The temperature and humidity recorder has a built-in Swiss original temperature and humidity measurement unit, which has excellent measurement performance and strong anti-interference ability, and can automatically control vaccines The temperature and humidity changes in the storage environment are accurately monitored. The measurement point data is updated every 2 seconds during the operation of the equipment (CFDA requires at least 1 minute). On the one hand, the data is displayed on the built-in LCD screen, and on the other hand, it is communicated through 4G. Upload to the remote monitoring platform;

The temperature and humidity recorder is designed with buttons. Through the buttons, we can set the normal data storage interval and the alarm data storage interval. Both of these storage time intervals are factory defaulted to 1 minute, but the device supports It can be set between 0~1999 minutes, so in the vaccine storage, we can modify various storage time intervals by pressing buttons or sending SMS.

Most vaccines are required to be stored in an environment of 2~8℃. If the temperature and humidity of the monitoring vaccine storage environment exceed or fall below this limit, the storage interval of the temperature and humidity recorder will automatically change from the normal data. The storage interval is switched to the alarm data storage interval, and the data storage interval will become faster. At the same time, the added person in charge (1~5) will be sent to inform the temperature and humidity of exceeding the limit in the form of a text message. If you are near the freezer where the vaccine is stored, The alarm sound from the recorder itself can be clearly heard.
The temperature and humidity recorder has GPS automatic positioning function, which can directly interact with satellites to obtain the current latitude and longitude and accurate time. Whether in vaccine delivery or after the vaccine delivery is completed, vaccine manufacturers, consignees, or supervision departments can log on to the cloud platform and view the real-time transportation trajectory and historical transportation trajectory of the transportation vehicle through the map.


When the vehicle arrives at the destination, the driver can directly connect the 4G embedded temperature and humidity recorder to the printer via Bluetooth, and print out the entire transportation data through the printer, together with the cargo Hand over to the consignee.

Remote monitoring center: environmental monitoring cloud platform
This platform is a remote monitoring software developed, which is the management center for monitoring the temperature and humidity monitoring system for drug storage. It supports web pages, mobile apps, and WeChat Various login methods such as official accounts, the interface is completely neutral, supports multi-level access, supports customers to add sub-accounts, users can log in to the back office with their accounts anytime and anywhere, check the real-time data of the drug warehouse, query, download, and print historical data, etc. .
4G Embedded Vaccine Cold Chain Temperature and Humidity Online Monitoring System is in compliance with Article 21 of '2017 Version of 'Vaccine Storage and Transportation Management Regulations': The temperature and humidity records during vaccine storage and transportation can be paper or can The electronic format for reading, the temperature and humidity records must be kept until the vaccine’s validity period exceeds 2 years for future reference.

Under the catalysis of the new crown vaccine, the development of the biomedical low-temperature storage industry is expected to accelerate, and the vaccine cold chain transportation industry has a high threshold, but the general fresh cold chain companies must get involved in the vaccine cold chain in the short term. It is not easy and requires a certificate to work, and relevant companies should prepare as soon as possible.
