[Qiaobao.com News] China’s State Council’s Joint Prevention and Control Mechanism released data on the 19th. As of September 18, 2021, 31 provinces (autonomous regions, municipalities) and Xinjiang Production and Construction Corps have reported a total of 217.4043 million doses of new coronavirus vaccines. The total number of people vaccinated reached 1,100,842,000, of which 1,022.207 million had been vaccinated, accounting for 78% of the country’s total population. The total number of vaccination doses and the number of people covered rank first in the world, and the population coverage rate ranks among the highest in the world.
According to Xinhuanet and Beijing Daily, in April this year, Wang Huaqing, chief expert of the China Centers for Disease Control and Prevention's immunization program, said that China will build an immune barrier in the future and it may require more than 1 billion people to be vaccinated against the new crown vaccine. The WHO also set the threshold for herd immunity at 60% to 70% in November last year.
But at present, delta mutant virus is raging around the world, and "breakthrough infections" are frequent. In August of this year, Zhong Nanshan, an academician of Chinese Academy of Engineering , said that research on the previous Guangzhou epidemic showed that China's domestic inactivated vaccine has an overall protection rate of close to 60% against Delta strains and a critical illness protection rate of 100%. The latest data show that the antibody level increased by more than 10 times when another dose was given 6 months after the second dose of domestic inactivated vaccine. After more than 80% of the population is vaccinated, China can establish effective herd immunity.
In addition, Academician Zhong Nanshan said that the latest information shows that the antibody level increased by more than 10 times when the second dose of domestically-made inactivated vaccine was vaccinated 6 months later.
In July of this year, China has launched the new coronavirus vaccination for people aged 12-17. On September 16, experts from the Chinese Center for Disease Control and Prevention said that people under the age of 12 are considered to be included in the scope of vaccination.
Moreover, China plans to start from the end of September, in accordance with the time interval of 6 months, in September, October, and November to complete the two tasks before March 1, April 1, and May 1. The 18-59-year-old key population vaccinated with doses of inactivated vaccines will receive booster immunization. At present, Henan and Zhejiang provinces have started to strengthen injections.(End)
