The cumulative number of COVID-19 vaccines nationwide has exceeded 200 million doses, the coverage rate of COVID-19 vaccine among medical staff has exceeded 80%, and the vaccine can prevent the emergence of mutant strains... On the 21st, the State Council’s Joint Prevention and Control Mechanism held a press conference to introduce the relevant situation of COVID-19 vaccination.

Over 200 million doses of the new crown vaccine have been vaccinated nationwide

　　Mi Feng, spokesperson for the National Health Commission, said that up to now, more than 200 million doses of new crown vaccine have been reported nationwide.

　　Recently, some people reported that it was difficult to make an appointment for the second dose.

When the state allocates and supplies vaccines to provinces, it has fully considered the demand for the second dose as scheduled.

All localities must make accurate deployment to ensure that the second dose of vaccination is completed within 8 weeks to avoid the situation where the injection is given but not given. The National Health Commission's stationed working groups will also strengthen supervision on this.

Medical staff's new crown vaccination rate exceeds 80%

　　Li Dachuan, deputy director of the Medical Administration and Medical Administration Bureau of the National Health Commission, said that starting from last year, in the vaccination of key populations, we have regarded medical staff as one of the key populations and prioritized vaccinations.

So far, the vaccination rate of medical staff has exceeded 80%.

Does the new crown vaccine require a booster shot?

　　Shao Yiming, a member of the expert group for vaccine research and development of the scientific research group, said that the overall time limit for our current vaccine use is about half a year. These data are in the process of collecting and analyzing. Various vaccine manufacturers, including the immunization planning departments of various countries, are studying these. data.

　　After vaccination in accordance with the immunization program, when to strengthen, a scientific decision must be made based on the data.

We may also be like other diseases spread by the respiratory tract, such as influenza, which need to be strengthened every year. This is awaiting analysis of our final data.

Can vaccination be continued during May 1st?

　　Cui Gang, the second-level inspector of the National Health Commission's Disease Control Bureau, said that at present, all localities are actively and orderly promoting the new crown vaccination work in accordance with the deployment of the Party Central Committee and the State Council.

In the implementation process, we have also repeatedly asked all regions to improve refined management. For example, we should make appointments for vaccination to avoid long waiting in line for the masses, or avoid the situation of "the appointment has been made and cannot be called by the time". appear.

　　He also emphasized that in the next step, we will continue to instruct all localities to make overall arrangements for inoculation work including the May 1st holiday from the perspective of convenience for the masses and improvement of service quality.

A positive nucleic acid test is the primary diagnostic criterion

　　Li Dachuan, deputy director of the Medical Administration of the National Health Commission, said that on April 14th, the National Health Commission and the Bureau of Traditional Chinese Medicine jointly issued the "New Coronavirus Pneumonia Diagnosis and Treatment Plan (Trial Eighth Revised Edition)", revised Compared with the eighth edition, there are two main changes.

　　First, the expression of diagnostic principles has been added.

The principle of diagnosis emphasizes that comprehensive judgments should be made based on epidemiological history, clinical manifestations, and laboratory test results.

　　Second, it is necessary to make a positive nucleic acid test for the new coronavirus as the primary criterion.

This is a big change.

In addition, antibody testing has some descriptive changes in the diagnosis of suspected cases and the diagnosis of confirmed cases.

　　In the part of diagnosis, the content of antibody detection has been adjusted.

In the diagnosis of suspected cases, we made it clear that if the antibody is positive for those recently vaccinated, it will not be used as a reference indicator.

In the diagnosis of confirmed cases, it is also pointed out that antibodies as a diagnostic criterion are limited to cases where there has been no recent vaccination.

Vaccines can prevent the emergence of mutant strains

　　It is said that the global promotion of new crown vaccination on a large scale may accelerate the mutation of the virus, and an immune escape response of the virus will occur.

In response, Shao Yiming responded that this statement should lack scientific basis.

　　Vaccines can block the spread of the virus. The virus cannot replicate when it does not. If it cannot replicate, it will not produce more mutant strains. In this case, the vaccine will definitely play a positive role and will not promote more. The emergence of mutant strains.

　　Through the widespread promotion of vaccines, we can still buy time for future viruses to mutate, enabling our companies and our R&D institutions to study a new generation of vaccines against mutant strains for the emergence of mutations.

Therefore, in this sense, vaccines can definitely prevent the emergence of mutant strains, rather than promote its emergence.
