In the use of RFID technology for vaccine safety traceability system, according to RFID technical requirements, vaccines are affixed with electronic tags at the time of production. Vaccines must be scanned in circulation, sales and other links. The system automatically compares them. If the information does not match, A warning will be automatically issued. More importantly, technically speaking, the entire cold chain transportation link of the vaccine can be opened up with the temperature control system and the electronic supervision platform, so that the cold storage technical standard of each vaccine can also be traced, that is, in addition to the traceability of its source, Even other technical requirements to ensure quality and safety can be traced, and eventually become the verification of the fulfillment of responsibilities, backed by such advanced technology, then the case of hundreds of millions of dollars in vaccines can hardly happen easily.

In February this year, the public security organs of Jinan City, Shandong Province, seized a case of illegal operation of vaccines. The criminal suspect Pang Moumou and his daughter Sun Mou, without obtaining any drug business license, used a large number of 25 types of human second-class vaccines or biological products for the prevention and treatment of Japanese encephalitis, rabies, influenza and other viruses, without 2 to 8 ℃ The cold chain storage flowed into many places across the country through various channels, involving 24 provinces and cities, and the value of the case was more than 0.57 billion yuan.

As soon as the news was exposed, the author's circle of friends was instantly swept by the vaccine incident. Some media friends reported on the incident, and some mothers who had just been upgraded to mothers or had two children commented with panic when forwarding such news, and even made comments about not taking their children to vaccinate.

Vaccination can prevent related diseases, this is the scientific conclusion, there is no doubt. The vaccine incident is reselling vaccines and illegal operation, which is an offence. The problem in the vaccine incident is that it is not stored and transported in the cold chain in accordance with the regulations. Some of it is a temporary vaccine, and there is a risk of expiration and deterioration in the circulation process. That is, if the cold chain is not stored and transported in accordance with the regulations, there will be a risk of vaccine failure, and the failure of the vaccine is not equal to the toxic vaccine. According to the report of the National Vaccination Abnormal Response Monitoring System, no abnormalities have been seen in the past five years (Pang Moumou and his daughter started in 2010), especially in Shandong and Henan provinces where the vaccine involved is more prominent. Therefore, we should treat this vaccine incident rationally to avoid unnecessary panic.

Things have happened, we can do is to minimize the loss. For example, to find out which provinces, regions, hospitals, maternal and child health centers and other users of these problematic vaccines have flowed to, and to find out who has been vaccinated and who has not yet been vaccinated. This allows us to target and compensate the victims who have been vaccinated with the problematic vaccines, while the vaccines that have not yet been vaccinated are recalled to minimize losses.

However, the number of vaccines sold by Pang's mother and daughter cannot be accurately counted. According to Jinan police, the 26 books seized in Pang's residence only recorded its vaccine sales data for more than one year, while Pang's bank account used to settle vaccine payments had earned as much as 0.31 billion yuan in the past five years. The inability to accurately count vaccines undoubtedly increases the difficulty of solving the problem. Just imagine, if the source of the vaccine can be queried and the destination can be traced, even if problems are encountered, they can be solved quickly, minimizing losses and reducing the chance of panic.

The food safety traceability system has been used in many fields including pork slaughter, food traceability, etc., and has also been used in the medical system, and has a good effect and reputation. In the field of vaccines, we can also consider introducing a security traceability mechanism. Each vaccine is labeled with an electronic label. Each preparation and each batch of vaccines has its own unique electronic number, which is equivalent to the vaccine. "ID card". After production, the whereabouts of the vaccine can be traced at any time. Such an electronic tag can realize the anti-counterfeiting function of commodities due to its characteristics such as code uniqueness and data replication difficulty. Transparent management is truly realized in all aspects of vaccine production, circulation and sales, and then a comprehensive drug traceability system is constructed to meet the quality and safety requirements of the society, and to realize the whole process management and monitoring of drugs from manufacturers to consumers.

In the use of RFID technology for vaccine safety traceability system, according to RFID technical requirements, vaccines are affixed with electronic tags at the time of production. Vaccines must be scanned in circulation, sales and other links. The system automatically compares them. If the information does not match, A warning will be automatically issued. More importantly, technically speaking, the entire cold chain transportation link of the vaccine can be opened up with the temperature control system and the electronic supervision platform, so that the cold storage technical standard of each vaccine can also be traced, that is, in addition to the traceability of its source, Even other technical requirements to ensure quality and safety can be traced, and eventually become the verification of the fulfillment of responsibilities, backed by such advanced technology, then the case of hundreds of millions of dollars in vaccines can hardly happen easily.

Leaving aside moral factors in this vaccine incident, imagine that if the source of the vaccine can be queried, the destination can be traced, the responsibility can be investigated, and transparent supervision can be realized in all links from the production of the manufacturer to the final vaccination, then those problematic enterprises and businesses with lack of morality will have nowhere to hide.
