At present, China is speeding up the new crown vaccination in key areas, populations and cities. As of 24:00 on April 10, a total of 164.471 million doses of Xinguan vaccine had been reported nationwide.
Wang Huaqing, chief expert of China CDC's immunization program, said that in order to build an immune barrier in our country, more than 1 billion people may need to be vaccinated with the new vaccine. The higher the vaccination rate is, the stronger the immune barrier will be. We still have a long way to go.
Although in the past week, the daily coverage of new crown vaccine in China has increased rapidly from 34 million to 7 million, it is still at a low level compared with some countries with 40% or even 60% coverage rate.
Wang Huaqing said frankly that the research and development of new crown vaccine has gone through preclinical, clinical phase I, phase II and phase III before it is put on the market. After it is put on the market, it is necessary to carry out research, which is a guarantee for the safety of the vaccine.
Novel coronavirus pneumonia is a risk factor for Wang Huaqing. Any vaccine has its risk. We have a million per cent of the adverse reaction or severe allergic reaction to the vaccine. Compared with the 2% of the new crown pneumonia, we can see that the harm brought by the new crown is very great. We can also take some measures to minimize the risk.
At a time when there are still people at home who have a wait-and-see attitude towards vaccines, wondering whether it is necessary to fight and whether they can fight, at least 70 countries and regions in the world have approved or agreed to buy Chinese vaccines, and many foreign leaders have vaccinated Chinese vaccines early. However, due to the strong control of the epidemic in China, some people are still waiting and expecting a better vaccine.
Wang Huaqing said that if everyone delays the vaccination, then our immune barrier will never be established. Our desire to take off the mask may not come true. If everyone vaccinates quickly, the barrier may come one day earlier, and we can return to our normal life as soon as possible.
In addition, Wang Huaqing also said that although we have seen virus mutation, vaccination is still useful at present. In view of the virus mutation, scientists in various countries are also trying to find a way to monitor the mutation, and to find corresponding solutions for those that may affect the effect of vaccine.
With the development of new crown vaccination, some of the original restrictions also changed. Just last month, Shanghai and Beijing successively organized to vaccinate elderly people aged 60 and above who have vaccination needs and good basic health. In the early stage of vaccination, people over 60 years old are not recommended to be vaccinated. In this case, we have also given corresponding suggestions in the guidelines. If you get pregnant after vaccination, you don't need to take special measures. Follow up health care and follow-up work during pregnancy are the same as other people's measures.
Which of the five new vaccines should be used?
In the research and development of new crown vaccine, China has always been the first in the world. At present, the new coronavirus vaccines of five manufacturers in China have been approved for conditional marketing or emergency use, and all of them are free of charge. Which vaccine should be chosen to vaccinate themselves is also a problem that many people are struggling with.
Wang Huaqing: the reason why the new crown vaccine can be approved for use on the market actually meets the most basic requirements. In this case, it is up to the state to determine where to supply what vaccine and make unified deployment. We hope to vaccinate as soon as possible, establish an immune barrier as soon as possible, and try not to consider individual differences, because if there is a big difference, there must be a way.
