What is the level of "strengthening needle" antibody?

  China News Agency, Beijing, October 30 (Reporter Guo Chaokai) The current round of the epidemic in mainland China has spread to more than 10 provinces, and the transmission chain is complicated.

Has the current epidemic been effectively controlled?

Why is the proportion of severe cases so high?

What is the level of antibodies in the "enhanced needle"?

Through a series of data released by the press conference of the Joint Prevention and Control Mechanism of the State Council of China on the 30th, we can get a glimpse of the current situation and effectiveness of the prevention and control of the epidemic.

14 province reports added in the past 14 days

  Recently, the new crown epidemic abroad is still at a relatively high epidemic level, and the epidemic situation in some neighboring countries is rising rapidly, and China's foreign defense import pressure continues to increase.

As of 24:00 on October 29, in the past 14 days, 14 provinces across the country have reported new local confirmed cases or asymptomatic infections. The current epidemic situation is still developing rapidly, and the prevention and control situation is severe and complex.

  It is worth noting that the epidemic situation has developed rapidly in Heihe, Heilongjiang since the case was reported on October 27.

At present, new cases are mainly found through screening of all employees and active medical treatment, suggesting that community transmission has occurred in the local area, and there is a risk of spreading and spilling.

Wu Liangyou, deputy director of the Disease Control Bureau of the National Health Commission, said that according to the current results of circulating and virus sequencing, the current epidemic in Heihe is not related to the local epidemics in Inner Mongolia, Gansu and other places. It is an epidemic caused by a new imported virus.

The State Council’s Joint Prevention and Control Mechanism has dispatched a working group to Heihe for guidance.

No spillover cases in Ejina Banner for 4 consecutive days

  In general, the current round of the new crown epidemic has many spots, wide coverage, and long lines, and Ejina Banner in Inner Mongolia, where cases are relatively concentrated, has also become the focus of attention of all parties.

Wu Liangyou said that since October 25, Ejina Banner in Inner Mongolia has not found any spillover cases for 4 consecutive days, and the spread of the epidemic and spillover risks have been effectively controlled.

In recent days, newly-increased cases in the local area were mainly found in centralized isolation points. The effectiveness of various prevention and control measures in the early stage began to show, and the spread of the epidemic in the community was basically contained.

  In addition, Hubei, Hunan, Sichuan, Guizhou, Shaanxi and other provinces have had no new cases for more than 4 consecutive days, and the epidemics in these areas are being effectively controlled.

The epidemic situation in Beijing, Hebei, Shandong, Qinghai, Ningxia and other provinces is basically stable.

40% of patients over 60 years old

  The outside world is concerned that the large proportion of severely ill patients diagnosed is a major feature of this round of the epidemic.

Guo Yanhong, Inspector of the Medical Administration and Hospital Administration of the National Health Commission, said that the epidemic involved elderly tourism teams, so the proportion of elderly people over 60 years of age was higher. According to rough statistics, the proportion of patients over 60 years old is 40%, which is higher than previous epidemics. The proportion of people over 60 years of age who are infected-18.5% is higher than the average. In addition, some elderly people have underlying diseases, so this time the proportion of severe illnesses is relatively high.

  In response to this round of medical treatment, Guo Yanhong said that the Health Commission focused on several measures: one is to concentrate patients, resources, experts, and treatment in accordance with the principle of "four concentrations"; the other is to send strong national experts ; The third is to establish an online consultation system to conduct online expert consultations for high-risk patients and critically ill patients in various regions; the fourth is to allocate convalescent plasma and specific immunoglobulins and other medicines and resources to various regions in advance to provide support for local treatment.

Since last year, a total of 1.523 million milliliters of convalescent plasma has been collected from recovered patients, of which 1.149 million milliliters have been used for clinical treatment, providing strong support for the treatment of patients.

"Strengthening Needle" after the full moon, the antibody level will increase by about 5 times

  In response to the spread of the new crown epidemic, many places across the country have initiated the "intensified injection" of the new crown vaccine.

What is the antibody level of the "booster needle"?

In response to this, Wang Huaqing, chief expert of the Chinese Center for Disease Control and Prevention's immunization program, responded that from the current domestic and foreign research results, after the application of the new crown vaccine, its antibody level has declined over time.

By vaccinating "booster shots" and increasing the number of doses of vaccination, the neutralizing antibodies that have been gradually reduced can increase or rebound rapidly.

The study found that the level of antibodies detected one month after the third shot of some new crown inactivated vaccines is about 5 times higher than that of one month after the second shot. Some will be higher.

  As of October 29, the country has reported a total of 2.262226 million doses of new crown virus vaccine, and the number of people who have completed the entire vaccination is 1.070.386 million.

Strive to complete the whole course of vaccination for people aged 3-11 by December

  Recently, many places across the country have launched new coronavirus vaccination work for people aged 3-11.

How safe is the new crown vaccine for people aged 3-11?

Wu Liangyou said that according to the expert opinions of the vaccine research and development team of the scientific research group, the safety and immunogenicity of the new coronavirus inactivated vaccine in people aged 3-11 years are not significantly different from those over 18 years old.

  At present, the Beijing Institute of Sinopharm, Wuhan Institute of New Coronavirus Inactivated Vaccine and Kexing Zhongwei New Coronavirus Inactivated Vaccine have been approved for emergency use in people aged 3-17.

The State Council’s joint prevention and control mechanism has further expanded the scope of vaccination and adjusted the target population of vaccination from 12 years old to 3 years old in consideration of China’s vaccine production capacity, vaccination capacity, clinical trial situation and actual prevention and control work according to relevant work progress. ; Through vaccination, provide better protection for people aged 3-11.

Wu Liangyou said that in the follow-up, the follow-up will continue to follow the principle of informed consent and voluntariness, and actively guide the 3-11-year-old non-taboo people to "should take all of them", and strive to complete the entire vaccination before the end of December.
