vaccine research and development is very rigorous
delivery is strict without worrying
Zhou Jiushun introduced that the birth of a vaccine usually requires five steps: the first is the research of virus species and cells, the acquisition of immune sources, and the second It is the production process research, the third is the quality research, and the fourth is the animal experiment and human clinical research. Finally, the safety and effectiveness of the vaccine will not enter the marketing approval stage.

In the press conference of the Joint Prevention and Control Mechanism of the State Council held on December 31, 2020, it was announced that Sinopharm Group China Bio-New Crown Inactivated Vaccine received conditional preparations from the State Drug Administration On the market, there are data showing that its protection rate is 79.34%, which achieves the unity of safety, effectiveness, technology, and affordability, and meets the relevant standards of the World Health Organization and the National Food and Drug Administration.
So, how did Sichuan carry out the distribution and preservation of the new crown vaccine? Can the entire process guarantee the quality and safety of the vaccine? Qi Qi said that as a biological product, the quality of the new crown vaccine is strictly guaranteed. Therefore, the whole process is delivered under cold chain conditions. Vaccine manufacturers, delivery units, disease control centers and inoculation units are strictly in accordance with the "Chinese People The relevant requirements of the Republic’s Vaccine Management Law and the Vaccination Regulations require storage and transportation of vaccines.

Qi Qi told reporters that in order to ensure the safety of the new crown vaccine delivery and vaccination, Sichuan uses " one increase, three strict " as the starting point to ensure vaccine quality: " one increase "That is, Sichuan has increased its investment in cold chain equipment (including refrigerated trucks, vaccine transport trucks and cold storage) across the province."Strong7strong three strict " means strict transportation, strict storage and strict use. After receiving the new crown vaccine, each CDC and vaccination unit will put it in the cold chain environment and strictly enforce the cold chain space. The temperature monitoring, every inoculation details of the inoculation operators are also strictly regulated. "A series of measures can effectively ensure that the new crown vaccine can maintain a strict cold chain environment from the production of the new crown vaccine to the use of the vaccinators, and then to the time when everyone is vaccinated."
It is reported that Sichuan's financial investment last year was 7,000. More than 10,000 yuan was used to equip the cold chain transport vehicles and cold storages of the province's disease control agencies to strengthen the protection of vaccines in the transportation and storage links.
vaccine quality is safe and reliable
Sichuan has an adverse reaction management mechanism
So is the new crown vaccine safe enough after it is injected into the human body? Zhou Jiushun said that after vaccination, the human body will produce the protective antibody , and some vaccines will also enable the body to produce cellular immunity and form the corresponding immune memory . In this way, the human body has immunity against diseases. Once the new coronavirus invades the human body, the antibodies produced by the vaccine and the cytokines released by cellular immunity can recognize, neutralize or kill the virus, and immune memory also quickly mobilizes the immune system to function, preventing the virus from continuing to multiply in the body, thereby To achieve the purpose of disease prevention.
Zhou Jiushun said that Sichuan is taking a number of measures to ensure the safety of this new crown vaccination : At present, each vaccination site in Sichuan has on-site guarantees for medical institutions above the second level, and they are proficient in vaccine abnormalities. Support personnel who respond to treatment measures and first aid skills are on standby at any time. In addition, the designated treatment hospitals near the vaccination unit have established green channels, and investigation and disposal teams for suspected adverse reactions of vaccination have also been established in various places. "Through the above measures, we will do our best to ensure the safety of the people's vaccination."
"From Judging from years of experience in vaccine production and use,The vaccines produced in our country are very safe and reliable, and they have also made great contributions to the reduction of various infectious diseases. I have already been vaccinated against the new crown. Isn’t it a livelihood? What’s the matter? "Zhou Jiushun said.
