Your concerns about the new coronavirus vaccination are all here

best way to stop the new coronavirus is through vaccines. Starting from December 15, 2020, China began to carry out new coronavirus vaccination work for nine key groups of people, including cold chain practitioners, customs border control, medical and health institutions, as well as people closely related to our daily life in the transportation, logistics, water, electricity, heating, coal, gas and other public areas. At present, more than 12 million doses have been inoculated. In the course of the steady progress of vaccination, people may have one way or the other questions, such as whether to get vaccinated, what vaccine is better, whether it is safe, whether antibodies will be produced, and so on. With these questions, the reporter visited the vaccination site, but also interviewed relevant experts.
8 a.m., the street vaccination site of the Sheep Shop in Haidian District of Beijing was full of people waiting to be vaccinated. Reporters see that the vaccination site is divided into 5 areas, eligible inoculators can enter the waiting area.
Beijing Haidian District SheepFang Shop Community Health Service Center Chief Nurse Chen Xiaoshuang: up to the second floor after there will be staff to let everyone queue to fill out an information card, with the patient's name, number, vaccination time, there are some precautions, is to ensure the safety of vaccination.
complete the information card and the vaccinator enters the registration area.
Chen Xiaoshuang, Chief Nurse of The Sheep Shop Community Health Service Center in Haidian District, Beijing: Fill in the informed consent form in the registration area to answer the patient's health consultation, and each doctor has a detailed understanding of the person who was vaccinated.
inoculated persons are advised to return during a doctor's inquiry, or further examination is done to confirm suitability for vaccination. For health consultation is no problem, the doctor agreed to be vaccinated, and signed the informed consent for vaccination, the identity information is entered. After the identity information is entered, you can enter the vaccination area. After vaccination, enter the observation area for 30 minutes. During the stay, once the inoculator has an adverse reaction, it enters the emergency disposal area of the vaccination site.
the vaccination is completed, the vaccinator can find his or her vaccination information in Beijing Health Bao. Recently, China's epidemic shows a multi-local outbreak and sporadic distribution of state, compared with the previous, the situation of prevention and control is complex and serious. But some people still have doubts about whether the new coronavirus vaccine will be tested or not.Zheng Zhongwei, head of the special working group on vaccine research and development of the joint prevention and control mechanism and director of the National Health and Wellness Commission's Medical and Health Science and Technology Development Research Center, said: At present, the cumulative number of infections worldwide has exceeded 90 million, and we have not yet seen an inflection point in the whole epidemic. The experience gained from the victory over major infectious diseases in human history, if we rely entirely on natural immunization, is at the expense of the death of a large number of people, and the ultimate weapon in the real fight against infectious diseases in modern science is vaccines.
Although China's new crown pneumonia epidemic as a whole has been better controlled, but as long as the local outbreak, it will be controlled and upgraded, want to restore normal life as soon as possible, we have to let large-scale population vaccination of the new coronavirus vaccine. Does vaccination mean 100% protection?Zheng Zhongwei, head of the special working group on vaccine research and development of the Joint Prevention and Control Mechanism and director of the National Health and Wellness Commission's Medical and Health Science and Technology Development Research Center, said: If you always understand vaccination, you will never be infected with the virus again, it will certainly always linger between vaccination and non-vaccination, because no vaccine in the world can achieve such an effect.
how protective can an effective vaccine be?The joint prevention and control mechanism of the scientific research team vaccine research and development team leader, the National Health and Health Commission medical and health science and technology development research center director Zheng Zhongwei: the degree of human infection with the new coronavirus is divided into 11 levels, the lowest level is 0, that is, will not be infected, and then down is asymptomatic infected, and then there are symptoms, and then down need to be hospitalized, and then down may appear some serious, and finally serious cases will appear death. If this vaccine can prevent death, serious illness and hospitalization, is it worth it?
, the vaccine is unique in that it is faced with a group and has a limited effect if it is only given by someone else.
Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention: The role of vaccines is mainly to build a mass immune barrier. Without an immune barrier, it will spread, or if it becomes popular again, the protective measures taken are actually the same.
, according to experts, the vaccine to play a real virus blocking effect, not only to fight, but also to fight. Because different infectious diseases are not the same infectious power, blocking the epidemic of infectious diseases in the population immunity is not the same.
Huaqing, chief expert on immunization programs at the Centers for Disease Control and Prevention in China: If measles is to be eliminated, the epidemic is interrupted by a 90 to 95 percent increase in immunity among the population. About the new crown now all countries are doing research, in the future if you want to control it, the proportion of the population must reach a certain high degree, in order to stop its popularity. Now there's a rough figure, about 50 to 70 percent.
50 to 70 per cent of the population means that 50 to 70 per cent of the population is immune to the virus and an immune barrier is in use to stop the spread of the new coronavirus. And the establishment of the immune barrier is premised.
Wang Huaqing, chief expert on immunization programs at the Centers for Disease Control and Prevention in China: If the population is vaccinated on a large scale, then this group of immunizations will soon be established, and the epidemic may slow down after it is established, or when a certain threshold is reached, its spread may stop.
Because of the outbreak, the development and vaccination of the new coronavirus vaccine has received widespread attention, many of them on whether antibodies are produced after vaccination, how long antibodies continue to last, and other issues continue to rise, some vaccinators even after vaccination to the hospital to test antibodies. How to correctly look at the problem of antibodies, after vaccination, antibodies are the only protective factors?
Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention: Antibodies are not the only protective factor, there is immune memory, as well as cellular immunity, in fact, after vaccination, the entire protection mechanism is comprehensive, not simply antibodies at work.
, the body produces protective antibodies, and some vaccines produce cellular immunity, forming corresponding immune memories. Once a new coronavirus invades the human body, the antibodies produced by the vaccine, cytokines released by the cell immune system will identify, menotypise or kill the virus, and immune memory will also mobilize the immune system to function, so that the virus can not continue to proliferate in the body, thus achieving the goal of disease prevention. Even if antibodies are reduced or even disappeared, the vaccine cannot simply be judged to be un protective.
as a new thing, the new coronavirus vaccine from research and development to the market, less than a year, this is different from many vaccines, so some people pay special attention to adverse reactions after vaccination. zheng Zhongwei, head of the special working group on vaccine research and development of the joint prevention and control mechanism and director of the Medical and Health Science and Technology Development Research Center of the National Health and Health Commission: I want to correct the view that vaccines are 100% safe. Any drug in the process of use, there will be some abnormal reactions due to individual differences, especially due to individual reasons there are some serious abnormal reactions which is inevitable.
, there are strict procedures and norms for monitoring abnormal reactions after vaccination. At the CDC in China, there is a monitoring system for adverse reactions, collecting and reporting the number of suspected adverse reactions, diagnosis numbers, diagnostic classification, etc.
Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention: According to the current surveillance of the new coronavirus vaccine, the occurrence of abnormal reactions is six out of 100,000, and the serious abnormal reaction is one in a million.
new coronavirus vaccine research and development to the market time is short, but the safety and ability evaluation is done in strict accordance with the procedures, experts believe that because the rapid launch of the vaccine has doubts, there is no need.
the world today, the two vaccines that are more inoculated are inactivated and mRNA. Vaccines on each route have their own characteristics and cannot be compared. Recently, several vaccine phase III clinical data have been released, after the
joint prevention and control mechanism released china's inactivated vaccine protection effectiveness of 79.34 percent, these data caused a lot of people's concern, there are people as a criterion to judge the quality of a vaccine, such a practice of science? Zheng Zhongwei, head of the vaccine research and development task force of the joint prevention and control mechanism and director of the National Health and Health Commission's Medical and Health Science and Technology Development Research Center, said: Horizontal comparison is not scientific, the scenario of each vaccine trial, the choice of subjects and the criteria for determining the third phase of the case are different, even if the same vaccine, in different countries, will also produce different clinical trial data.
is concerned about the new coronavirus mutation, experts explain that the relevant departments are constantly monitoring, the degree of virus mutation is not yet beyond the control of the vaccine.
our vaccine is safe and effective, and preparations are in place. Internationally, the safety and ability of Chinese vaccines have also been recognized by many countries, and many countries have already purchased Chinese vaccines. Experts also said that the vaccine as the best way to stop the current outbreak, the need for large-scale population vaccination to produce results. Therefore, we should fight as soon as possible to establish an immune barrier, as soon as possible to restore our normal state of life. It is understood that as the supply of vaccines continues to increase, the target population of vaccination will gradually expand. Stopping the outbreak requires the contribution of all of us.
