Zhang Dingyu, national honorary title winner of "people's hero" and deputy director of Hubei Provincial Health Committee, Cheng Shiming, Secretary General of China Anti Tuberculosis Association, and Zhang Wenhong, director of infection department of Huashan Hospital Affiliated to Fudan University, successively came to the seminar site of China MDR-TB ultra short course program research initiation meeting. < / P > < p > photo source: visual China < / P > < p > seminar lasted until 1:30 a.m. on the 24th. At the meeting and after the meeting, Zhang Wenhong talked about his views on seven hot topics related to the new crown vaccine. < / P > < p > is the new crown vaccine available? < / P > < p > some people are still hesitating whether to get the new crown vaccine. Zhang Wenhong said: < / P > < p > this is not a question of vaccine, it is a question of human nature. I look forward to a lot of things when I can't get them. Once I can easily get them, I will hesitate. This is true all over the world. It's normal for people to have such thoughts and worries about vaccines. But as time goes on, more and more people get vaccinated, and there's no problem, and you'll accept it. < / P > < p > about adverse reactions < / P > < p > in view of the adverse reactions that we are most concerned about, Zhang Wenhong said: < / P > < p > now the biggest worry about vaccines is adverse reactions. However, from the perspective of the whole world, the United States has inoculated more than 100 million doses, and the data show that the adverse reactions are completely acceptable; China's current vaccination amount of more than 75 million, the adverse reactions are also acceptable. < / P > < p > I have full confidence in the safety of vaccines in China. I have been vaccinated with the new crown vaccine and I have no adverse reactions. Of course, I don't mean other people don't, but from the current actual data, the incidence of adverse reactions after vaccination is very low. < / P > < p > people who are not vaccinated will suffer! < / P > < p > what happens if you don't get vaccinated all the time? Zhang Wenhong said: < / P > < p > at present, developed countries are rapidly completing the vaccination, and once they have completed the vaccination of the new crown vaccine, they will reopen. When the world's big economies, such as the United States, European Union countries, Japan and so on, reopen, if our country continues to close down, the impact on the economy and public psychology will be far greater than the losses caused by the new coronavirus. < / P > < p > when the door of the country is opened, people who have not been vaccinated will suffer losses, and they will be very worried wherever they go. < / P > < p > What are the benefits of vaccination? Zhang Wenhong said: < / P > < p > the new coronavirus will become a resident virus in the future, and there will always be. < / P > < p > for every individual, the reason for vaccination is simple: in case of infection in the future, I will be OK. &The protection rate of our inactivated vaccine is more than 90% to avoid severe disease and nearly 100% to avoid death. Therefore, vaccination from the national level is to block the spread, from the personal level is not to have an accident. < / P > < p > is it possible to reinfect with new coronavirus after new coronavirus vaccination? be on the cards. Vaccination is not 100% prevention, but after vaccination, even if the infection may be a large flu, or just a small flu, maybe a common cold, or asymptomatic. When can I take off the mask? < / P > < p > when can I take off the mask and breathe freely? Zhang Wenhong said: < p > < p > at least 70% of the vaccine protection rate can be said to constitute an effective immune barrier. &However, 70% is the minimum requirement, not necessarily enough, because the protection rate of vaccine is not 100%. If the protection rate is calculated as 90%, I think the ideal vaccination rate is above 80%, we can say that we can open the door safely. It will take about half a year to reach the 70% protection rate, which is estimated according to the ideal state. < / P > < p > how long can vaccination last? < / P > < p > for the period of validity of antibody produced by vaccination, Zhang Wenhong said: < / P > < p > the period of validity will become more and more clear with the time point, and then the data such as the duration of antibody will be available one after another. < / P > < p > antibody attenuation does not mean that there is no protection rate. We need one year or more to get this data. Many countries vaccinated earlier than us, and their data will come out first. < / P > < p > diagnosis after vaccination by doctors in Xi'an. Individually, it involves a lot of details. I don't know the details now. What are the details? For example, how long is the interval between his first and second stitches? After the second injection, it needs enough time to produce antibody and provide enough protection. In addition, the vaccine does not guarantee 100% transmission, and infection is still possible. For example, if you are exposed to more viruses, you may still be infected, but the condition will not be serious. Xi'an this diagnosis, his condition is not serious. < / P > < p > now there is only one case, and in science, only a sufficient number of people who have "breakthrough" in vaccine protection after vaccination can obtain the corresponding data. Judging from the current situation, we need not worry about it. According to Shangguan news client, Zhang Wenhong, at present, the developed economies in the world are carrying out mass vaccination, and it is expected that the establishment of immune barrier will be basically completed from June to September this year. After that, the world will be open and interconnected. If we do not complete enough vaccination, we will face great risks. "Previously, we could solve the problem through physical isolation, but in the future, < strong > if more economies achieve post vaccination mass immunization, we must also avoid the adverse consequences of the new coronavirus that far exceed its own." < / strong > < / P > < p > Wuhan was unsealed at 0:00 on April 8 last year. "At that time, many people were also worried: is it safe? At that time, I told President Zhang Dingyu that I particularly supported opening up. Otherwise, the socio-economic and even the psychological problems of the citizens caused by the long-term closure would be very serious. " Therefore, the role of vaccines is very important at this stage, Zhang said. thatSo, how much vaccination rate does the population need to achieve in order to really build the immune barrier? < / P > < p > "we calculate according to the mathematical model, if the number of new coronavirus transmission is 3 (that is, one patient can infect 3 people), then 70% of the vaccination needs to be completed before the protection rate is basically up to the standard. But this is the minimum requirement and may not be enough in many cases. " Zhang Wenhong explained that because the protection rate of the vaccine is not 100%, if the effective rate is 90%, then the vaccination rate should be further improved, and it is better to reach 80%, without a ceiling. " < / P > < p > photo source: photographing network < / P > < p > "some people ask: what if I don't get vaccinated? I can only say that if we don't get vaccinated, we will suffer losses. " Zhang Wenhong put it bluntly, "what the public is most worried about is the adverse reactions after vaccination. As of 24:00 on March 20, a total of 74.956 million < a target =" were reported nationwide_ blank" href=" https://news.163.com/news/search?keyword=%E5%89%82%E6%AC%A1 "> dosage < / a >, the number of vaccinations is growing steadily, it can be basically clear at present, and the adverse reactions are acceptable. < strong > in this era of we media, if there are serious adverse reactions after vaccination, won't everyone know soon? " < / strong > he preliminarily estimated that with the further liberalization of the vaccination policy, the number of inoculations per day in China may increase by more than 5 million in the next one or two months, and it will be close to 200 million in a month, which will greatly increase people's confidence. According to Zhang Wenhong, inactivated vaccines are the main vaccines on the market in China, and their safety is the highest among all vaccine sequences. "The safety of mRNA vaccines currently used overseas is also acceptable, and China will introduce them in the future." < / P > < p > finally, Zhang Wenhong made a suggestion for the general public, "vaccination can not be completed in one day. After confirming the health status, past medical history, allergy history and other information, the citizens who need to be vaccinated should go for vaccination as soon as possible, and make more full preparations for their foreseeable travel." < / P > < p > < strong > source: daily economic news, comprehensive Chutian Metropolis Daily, Shangguan news < / strong > < / P > < p >
