  With the spread of the delta strain and the stacking of autumn and winter factors, the risk of spread of the epidemic has increased.

Since the outbreak of local epidemics on October 17th, various parts of China have launched new crown vaccine booster immunization work for key populations, speeding up the construction of the entire population's immune barrier.

  In Beijing, the vaccination work in various districts is progressing in an orderly manner. Among them, the Chaoyang District has been inoculated with more than 100,000 doses of intensified injections for 3 consecutive days.

The work of vaccinating young people with the new crown has also begun.

  "I just finished the intensive injection, and I feel more at ease!" said Zhang Wenying, an employee of the IKEA Huiju Shopping Center store.

  Recently, the reporter saw in the North Gate Plaza of Huiju Shopping Center in Xihongmen Town, Daxing, Beijing. Before two mobile vaccination vehicles, vaccinators lined up in an orderly manner. Under the guidance of the staff, they signed and signed the informed consent form. Fill in the vaccination sheet, vaccinate the new crown vaccine, and stay in the observation room for observation.

  In Daxing District, where a cluster of epidemics occurred at the beginning of this year, 23 temporary vaccination sites quickly "returned to work", and 13 mobile vaccination vehicles also quickly set off into communities, villages, and business circles to provide convenience for vaccinators.

In Fengtai, Beijing, more than 8,000 merchants and more than 1,000 employees in the Xinfadi market were vaccinated with the new crown vaccine booster in batches.

  Since mid-October, cities such as Xi'an, Guangzhou, Hefei, and Beijing have successively launched intensified vaccination for key populations such as public security, fire protection, education, health care, transportation, and logistics.

  According to data from the National Health Commission, as of October 23, China has reported a total of more than 2.2 billion doses of new crown virus vaccines, and the number of people who have completed the entire vaccination has exceeded 1 billion.

  "According to the analysis of domestic and foreign research results, after vaccination, the effect of preventing infection, especially the prevention of severe illness and death, is better." said Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention. Compared with the vaccine, the risk of infection is greatly reduced."

  Wang Huaqing said that with the passage of time for vaccination, the level of neutralizing antibodies of the recipients is declining, and the protective effect is weakening.

Boosting immunity can increase antibody levels and quickly rebound antibody levels.

Therefore, it is very necessary to increase the number of vaccination shots after the entire course of the new crown vaccine.

  A few days ago, the State Council’s joint prevention and control mechanism comprehensively considered China’s vaccine production capacity, vaccination capacity, clinical trials and actual prevention and control work to further expand the scope of vaccination and adjust the target population for vaccination from 12 years old to over 3 years old.

  "We used to think that the incidence of new coronary pneumonia in children was low, but as the epidemic spreads globally, it has been found that the incidence of children has increased, and the severe illness and mortality rate in some countries have exceeded that of influenza." Wang Huaqing said.

  According to incomplete statistics, since mid-October, Hubei, Hainan, Liaoning, Gansu, Hebei, Beijing and other provinces and cities have launched new crown vaccination for people aged 3 to 11 years old, and Shanghai has launched new crown vaccination for people aged 6 to 11 years old. Work.

Jiangsu is expected to start the new crown vaccination for people aged 3 to 11 from November to December.

  The relevant person in charge of the Beijing Vaccination Organization Coordination Working Group stated that the dense population of schools and kindergartens can easily cause the local spread of infectious diseases. The new crown virus vaccination for people aged 3 to 11 years is an important part of building an immune barrier for the entire population. It is also an important measure to stop the spread of the new coronavirus.

  According to data released by the State Council’s Joint Prevention and Control Mechanism Scientific Research Team, the annual production capacity of China’s new crown vaccine is close to 5 billion doses.

  While ensuring domestic vaccine supply, Chinese vaccine companies also provide strong support for foreign vaccine demand.

According to Yang Guang, Chief Commercial Officer of Kexing Holding Biotechnology Co., Ltd., Kexing has provided many semi-finished and finished vaccines to foreign countries, and the current production capacity has exceeded 2 billion doses.

  Zhang Yuntao, chief scientist and vice president of Sinopharm China Biotechnology Co., Ltd., said that in order to meet the need to increase the supply of needles, China National Biotech has built a three-phase production workshop at the Beijing Institute of Biological Products and two phases of production at the Wuhan Institute of Biological Products. Workshops, sub-assembly workshops have been built in Lanzhou, Changchun, Chengdu, and Shanghai.

  "At present, we have established vaccine supply partnerships with more than 50 countries, and nearly 20 of them have initiated the promotion of intensified injections, and Kexing will make every effort to ensure the supply of vaccines." Yang Guang said, "In the epidemic In China, no country can do its own thing. Only when we work together can we successfully defeat the epidemic.” (Reporter Luo Xin, Li Chunyu, Klin Miaomiao)
