htmlOn the afternoon of April 21, the State Council’s Joint Prevention and Control Mechanism held a press conference to introduce the relevant situation of COVID-19 vaccination.
Do people who have been vaccinated need to continue to get vaccinated afterwards? At the meeting, Shao Yiming, a member of the expert group of the vaccine research and development team of the scientific research and development team, said that the overall time limit for vaccine use is about half a year, and various vaccine manufacturers, including immunization planning departments of various countries, are studying these data. When should be strengthened, scientific decisions must be made based on the data. "It is possible that it will be like other respiratory diseases such as influenza, which need to be strengthened every year, and this is subject to the analysis of the final data."
National Health Commission:
Avoid the situation of "a appointment is made but cannot be received"
At the meeting, Cui Gang, a second-level inspector of the National Health Commission's Disease Control Bureau, introduced that all regions are actively and orderly promoting the vaccination of the new crown vaccination work in accordance with the deployment of the Party Central Committee and the State Council. During the implementation process, we have also repeatedly asked local governments to improve refined management, such as making appointments and vaccination work, avoids people queuing for a long time, or avoids the occurrence of "the appointment has been made and cannot be made at that time".
Recently, we have re-deployed and re-trained vaccination work based on how to improve service quality in our current work. In the next step, we will continue to guide all localities to coordinate the vaccination work arrangements including May Day holidays from the perspective of facilitating the people and improving service quality. Our purpose is to improve the people's sense of gain, happiness and security.
Will large-scale promotion of COVID-19 vaccination accelerate virus mutation?
Experts dispelled the rumor
There is a saying that global large-scale promotion of new crown vaccination may prompt the virus to accelerate mutation, which is more infectious and more toxic. In this regard, Shao Yiming, a member of the expert group of the vaccine research and development team of the Scientific Research and Research Group, said that this statement lacks scientific basis.
Shao Yiming said that virus mutation is an eternal theme, especially the basis of mRNA virus mutation is that the virus will continue to replicate. How can this virus be replicated continuously? As an acute infectious disease, the entire course of the new coronavirus is only a few weeks. If it wants to continuously replicate, it must be transmitted from the infected person to the susceptible person. If it is not epidemic, there will be no chance to replicate, and if it cannot be replicated, there will be no more mutant strains. In this case, the vaccine will definitely play a positive role and will not promote the emergence of more mutant strains.
He said that even if there is no vaccine, after the virus infects the human body, the immune system will itself develop immune pressure on the virus, and under this pressure, it will also lead to the emergence of mutant strains. However, if the person who is is vaccinated in advance, then he will have basic immunity. After the virus enters the human body, it will produce a stronger immune response, the virus replicates less, and the chance of mutation is less.
Shao Yiming emphasized that through the large-scale promotion of vaccines, we can still "buy time" for future virus mutations, allowing our companies and R&D institutions to study a new generation of vaccines against mutant strains. So, in this sense, a vaccine can definitely prevent the emergence of a mutant strain rather than promote its emergence.
