　　Text/Yangcheng Evening News reporter Zhang Hua correspondent Wu Yuantuan Xu Jianying

　　Why do Chinese medicine practitioners who can keep in good health always make you eat less cold things? Yan Fang, director of the Classic Department of Traditional Chinese Medicine of Guangdong Provincial Hospital of Traditional Chinese Medicine, believes that if we want to be healthy, we must first protect our own yang, because the warmth of the yang makes our body move normally. The biggest harm of cold things lies in the loss of human yang, which leads to the weakening of human function. After the weakening of human visceral function, it is easy to cause stagnation of qi and blood stasis. Many of our diseases come from these bad habits that damage yang.

　　Habit 1 Eat a lot of fruit every day.

　　Fruit is rich in vitamins and dietary fiber, which is good for skin and body. So many women eat a lot of fruit every day, eat watermelon and cut it in half, and dig it with a spoon; Eating a bunch of grapes is like eating melon seeds.

　　Yan Fang, director of the Classic Department of Traditional Chinese Medicine of Guangdong Provincial Hospital of Traditional Chinese Medicine, believes that healthy people should eat 250-400g of fruit every day. Western medicine pays attention to the ingredients of fruit, such as "rich in vitamins", but Chinese medicine pays attention to its properties. However, we often ignore the cold or wet weight of fruits, and the storage and transportation are mostly refrigerated. In addition, our Lingnan area has the characteristics of less mountains and more water, and more cold in the middle soil.

　　Modern people, however, are generally cold because of their love of cold drinks, excessive stress and fatigue, abuse of antibiotics, frequent air conditioning and many other factors. This kind of physique, especially for cold and cold fruits, should be cautious and not eat more. Otherwise, excessive cold and dampness will hurt the spleen and stomach, leading to loss of appetite, loose stool, fear of cold and even eczema.

　　Yan Fang suggested that people who are cold and wet should not eat too much fruit. The ancients paid great attention to this point. They didn’t eat fruit on an empty stomach, the infirm didn’t eat fruit, and children and the elderly didn’t dare to give too much fruit to eat. For patients with deficiency cold and particularly greedy mouth, Yan Fang suggested that when eating fruit, a small amount of boiled water should be used for soaking or boiling, which can slightly reduce the coldness. Knowing your physique, choosing the fruit that suits you and tasting it in moderation are the "health tips" for eating fruit.

　　Habit 2 Drink herbal tea at every turn

　　There are few mountains and low terrain in Lingnan area, which shows that "rustic" is thin. The spleen and stomach belong to the soil, which will inevitably affect the function of the spleen and stomach. In addition, the climate here is hot and humid, and everyone thinks that it is necessary to remove more dampness and heat. Herbal tea can clear fire and quench thirst, and it tastes good. There are herbal tea shops all over the street, and the sales are also good.

　　However, eating too much herbal tea that can clear away heat, detoxify and eliminate dampness will further damage the spleen and stomach. The soil is thin and "the soil does not contain fire", so it is naturally easy to "fire" as a disaster!

　　Yan Fang said that repeated fires are mostly caused by deficiency fire, such as dry mouth and bitter taste, red eyes, oral ulcers, swollen gums, sore throat, nosebleeds, dry stools and so on. At the same time, it is accompanied by symptoms such as dull tongue color, pale lips, thin white or slightly greasy tongue coating, light urine color and smell, dry mouth and no desire to drink more, five upset and hot (hands, feet and heart, collectively called five hearts), insomnia and irritability, so the real cure for fire is to regulate the spleen and stomach. If the "rustic" is thick, it will naturally be difficult to get angry!

　　It is not necessary to put out the fire at the sight of the fire, but to get angry and reduce the fire. Drinking too much herbal tea will hurt Zhongyang, and the health will be damaged the day after tomorrow, causing endless harm. The correct way is that herbal tea should be moderate and lead to fire.

　　Habit 3: I have no time during the day and exercise at night.

　　The pace of work and life in the city is fast, and I really don’t have time to exercise during the day. After work, the night is clean, the weather is cool, running and playing ball games, and I feel very sour and refreshing. Plus, there is another reason to eat supper after exercise. Therefore, many people have no time during the day and are used to doing sports at night.

　　Yan Fang believes that improper exercise is better than no exercise. Night exercise calls the human body’s yang, which is contrary to the natural law of "doing at sunrise and resting at sunset", and even affects sleep and rest at night. In addition, supper will hurt the spleen and stomach.

　　Therefore, Yan Fang does not advocate night exercise, and it is the way to keep fit at sunset.

　　Habit 4 Stay up late and make up during the day.

　　At present, young people are under great work pressure and have many recreational activities. Many people are willing to overdraw their physical strength and consume their blood excessively. For example, they always like to stay up late. Others think that if you stay awake at night, you can make up your sleep time the next day.

　　In fact, staying up late is the most harmful to qi and blood. Therefore, people who stay up late usually look haggard and tend to get old. Chinese medicine believes that what is consumed during the day is the yang of the body, and sleeping at night can make the yang get full rest and nourishment. Staying up late for a long time will disturb the balance of yin and yang, qi and blood in the body. Various organs of the body may have different symptoms.

　　Yan Fang believes that the Tao is to preserve one’s health naturally, to do it at sunrise, to rest at sunset, and to stay up late at night is to call the sun be the spirit. Sleeping during the day is to block the yang, and you are not staying up at night, but living.

　　Habit 5 wash your nose with cold water every day

　　Patients with "allergic rhinitis" are very common, and most of them are allergic and have certain heredity. External stimuli, including cold air, pollen, indoor dust, mites, molds, animal hair, dander and poultry feathers, can all lead to nasal itching, continuous sneezing and a lot of clear water-like serous nasal secretions. Each attack lasts for more than one hour and often recurs.

　　Many people are used to washing their noses, thinking that it can clean the bacteria in the nasal cavity, enhance the resistance of the nasal cavity, strengthen the ventilation and drainage of the sinuses, and promote local blood circulation.

　　However, Yan Fang believes that this will consume the body’s yang, reduce the body’s resistance, take the initiative to induce cold pathogens to invade, and lead to recurrent rhinitis.

　　Experts say that washing the nose with cold water does not cure the symptoms, especially cold water washing the nose adds cold to the cold, which encourages cold pathogens to hide in the house, which is not beneficial but harmful. (Watchmaking/Du Hui)

　　"It only takes a few lines of code to build a regression model." Programmers recognize the performance of Google AutoML and think that the model designed by AutoML is comparable to that designed by machine learning experts. A few days ago, Google engineers introduced the Google AutoML project in China and Silicon Valley respectively.

　　Confused doubts followed — — AI evolved again? ! Already self-developed? Can control their own evolution? Is it to get rid of humans?

　　How many steps does evolution take?

　　AI has indeed evolved, and it can do more and more things and achieve remarkable results. Behind it is the "triple jump" of AI implementation path — —

　　Zhao Zhigang, a researcher at the Big Data R&D Department of Jinan Center of National Supercomputing, said: "At first, we used mathematical formulas and ‘ if… … then’ Wait for the statement to tell the computer what to do in the first step and what to do in the second step, teach it by hand, and then give the machine N groups of inputs and outputs. The rules or laws in the middle are learned by itself. "

　　"Before, many smart minds spent their whole lives studying how to extract effective features." Mo Yu, CTO of Smart Point, which focuses on intelligent shopping guide dialogue robots, explained, "The invention of neural network algorithm and the emergence of deep learning technology have made AI evolve to 2.0, and the work of extracting features is carried out by AI itself, and our work has also changed accordingly."

　　It is easy to explain the transition from "1.0" to "2.0" with the model of mathematical function: if the tasks of image recognition, semantic understanding and chess playing are all regarded as different Y=f(X), that is, the input picture, voice or chess move of "cat" is "x", and the output cat, answer and chess move is "y". Before deep learning, people find the formula corresponding to function F through their own analysis and tell it to AI. After deep learning, people input a lot of correspondence between x and y, and AI finds the formula corresponding to function f by itself.

　　"The specific content of the function F found by AI may be better than that found by humans, but humans don’t know it, just like a black box." Mo Yu said, "But the form of F is designed by AI researchers through research. If deep neural network is used, the modules in the network and the organization between modules are also designed in advance."

　　With the maturity and popularization of deep learning technology, there has been a specific pursuable experience in model construction. "The release of various common neural networks has made the threshold for employment lower and lower. Some ordinary model construction and optimization, just graduated students can get started in online learning tutorials. " Zhao Zhigang said.

　　When modeling becomes a learnable skill, AutoML appears. What it can do is the model design work of AI researchers. "It will help different companies build artificial intelligence systems, even if they don’t have extensive expertise." Google engineers recommend this. AI successfully evolved to 3.0.

　　In fact, AutoML still replaces the work that human beings can extract experience. "If people described a set of ‘ Road network ’ With the technical assistance of deep learning, the machine can find the optimal path as quickly as possible; Then AI can now design its own road network. " Zhao Zhigang was concise.

　　It can be seen that both deep learning and AutoML only replace the work that some groups of human beings have studied thoroughly. "What machines can do, try not to work by hand" is the life creed of many programmers, which gave birth to AutoML. Based on the same creed, Microsoft developed DeepCoder. "It can be used to generate programs that satisfy given input and output." Mo Yu said, but its performance is not satisfactory at present, and only some simple programs can be written.

　　Who is "God"

　　There is no doubt that the answer is human.

　　Since AI has evolved to a higher level of model design, what changes have taken place in the "hand of God"?

　　"An alchemist", Mo Yu vividly talked about his work in two words. "Smart is a professional intelligent customer service. The work of R&D personnel mainly focuses on problem modeling (how to turn actual problems into problems solved by artificial intelligence technology) and algorithm optimization (how to improve the effect of artificial intelligence algorithms)."

　　"refining" means constant debugging and improvement. "For a specific person, the more you throw your temper, the better. The more accurate the answer, the better." Mo Yu said, "Our X is the customer’s question, Y is the reply of the robot customer service, and the middle function F needs training."

　　This is not an easy task. If we divide the experience of human society into three categories: definite rules with formulas, knowledge that can be expressed in words, and feelings that can only be understood but cannot be expressed. The last category is the most difficult to ponder.

　　"Therefore, we try to build a perfect closed-loop feedback, understand the preferences of specific users, and finally achieve what they like through the expression of emotions and interests." Mo Yu said, "At present, it is in the stage of man-machine collaboration, but the acquisition of more and more samples will help our intelligent customer service to give accurate and pleasing answers."

　　It can be seen that not all fields are suitable for AI’s self-development. For example, in the aspect of problem modeling, how to abstract practical problems into machine learning problems can not be completed by AI. In the stage of AI2.0, R&D personnel also need to design the form of function F manually.

　　So, what will be the future of AutoML popularization?

　　"Humans are liberated from lower-level jobs." Zhao Zhigang said, "If the model design can be done by AI, then AI researchers will explore more the design of the basic modules that make up the model."

　　"Developing AI models with AutoML is similar to children playing with ‘ Lego ’ Toys. " Zhao Zhigang put it in simple terms, and the designers of Lego disassembled the whole world into detailed modules, so that everything could be used and then combined into complex models. The higher level of human work is to find basic units, that is, modules, for AI in different fields. For example, in the field of image recognition, humans have designed various modules such as convolution and pooling. "AutoML can build a model based on this, and constantly adjust the module combination to obtain a more reasonable output. The finer the module, the more versatile it can be, and the more self-developed AI can be used. " Zhao Zhigang said.

　　Extended reading

　　 Where are the talents needed by the industry?

　　Alleviating the shortage of talents is the main selling point of AutoML. "AI systems are blooming everywhere, but AI talents are far behind." Google explains why AutoML is indispensable. What is the current status of AI talents?

　　In 2017, the Global AI Talent Report and the BAT Artificial Intelligence Talent Development Report were released one after another. "The shortage of AI talents is real." Xu Wenjuan, vice president of Shengshi Investment Group, said, "The shortage of talents in start-up and development enterprises is particularly serious. From the current global perspective, the United States has the largest number of AI talents, and China’s AI talents can’t be compared with it in terms of number of people and experience. "

　　Zhao Zhigang has the same feeling: "China’s AI field is short of veterans, experts, generalists and top masters." The optimization and debugging of the model requires experience, the exquisite design of the model requires superb skills, and the application of AI in various industries requires compound talents. In addition, there are only a handful of top talents leading the development direction of AI, and most of them are abroad.

　　Xu Wenjuan introduced that China has the most AI talents in BAT (Baidu, Ali, Tencent). Generally, there are several kinds of background experiences of such talents, such as returnees, BAT work experience, or from universities or research institutes.

　　"AI self-development should not be able to replace people’s work in the short term, and there is still a long way to go." Xu Wenjuan said. Zhao Zhigang analyzed from an academic point of view: "Only when human beings design AI models in different application fields and further decompose them into a series of general modules, such as the periodic table of elements in chemistry, DNA and RNA in biology, can this self-development have more applications."

　　Line up for spicy food.

　　Tempting Gansu mala Tang.

　　"Bouquets of vegetables" are one after another, and enthusiastic diners are one after another. After Tianshui Mala Tang went out of the circle, this "sky-splashing flow" also began to flock to Lanzhou, and the passenger flow of major Mala Tang shops in the city continued to rise obviously. Embracing this wave of traffic dividends, on March 20th, famous local restaurants in Lanzhou took advantage of the situation to offer a new "Gansu Mala Tang" and add another fire with innovative dishes. Even the University of Science and Technology Beijing, thousands of miles away, issued an official announcement, "The campus canteen window, authentic Tianshui Mala Tang in Gansu, is officially launched"!

　　A Lanzhou hot spicy dip famous store huo Shang Jia huo

　　When visiting Lanzhou, Jin Lan Mala Tang in Anning District must be on the must-eat list.

　　At noon on March 19, looking at the endless diners, Ms. Chen, a citizen of Lanzhou, lamented: "Jin Lan Mala Tang, which is deeply loved on weekdays, has become more popular recently!" This is an old-fashioned Mala Tang shop in Lanzhou. The proprietress’s name is Wen Jinlan, and she is from Longnan, Gansu Province. She has been here for more than 20 years. After the hot spicy dip in Tianshui, more and more diners came here, and sometimes they even had to wait in line for an hour to eat.

　　In order to meet the huge passenger flow, it is normal for Wen Jinlan to get up early for nearly 20 hours every day. The reason why it is popular, in the view of the proprietress Wen Jinlan, is because of "popular taste, everyone likes it". The raw materials such as Gangu pepper, Wudu Dahongpao pepper, vermicelli specially customized from Dingxi and grain vinegar produced nearby have jointly contributed to the mouth-watering "spicy and hot".

　　"A large pot of vegetables, all kinds of ingredients wrapped in red juice, a spoonful of crisp sour radish, and the smell of oily spicy seeds between chopsticks directly hit the taste buds." Every meal, Yanji Mala Tang in Zhengning Road, Chengguan District, all the tables inside and outside the store are full. Many people ask, after more than 30 years of opening, people are so popular that there must be an exclusive secret recipe, right? Mr. Zeng, the boss, said frankly: "My wife and I are out-and-out Jianyang people in Sichuan. We have lived in Lanzhou for decades. We improved and adjusted the proportion of juice according to the tastes of local people, which reduced the hemp degree of pepper. It brings together Gansu local materials such as Dingxi Kuanfen and Gangu Chili, forming a unique flavor of Gansu Mala Tang. "

　　B Lanzhou local catering enterprises innovate dishes.

　　On March 20th, Duanji Hotel in Yantan, Lanzhou officially launched the new dish "Gansu Mala Tang". Yang Guoyan, Chairman of the Folk Food Committee of Longcai Association and Deputy General Manager of Lanzhou Duanji Catering Management Co., Ltd., told Benben News reporter: "In order to meet this wave of traffic, we have developed a new dish close to Tianshui Mala Tang, with ingredients such as Gangu Chili, Dingxi Kuanfen and Qin ‘an Zanthoxylum. As a Longcai hotel, our goal is to create a ‘ Ganwei hot spicy dip ’ The alternative ingredients will be more extensive, adding lily, yak meat and so on. " Yang Guoyan said that many employees in the store are from Tianshui. Through repeated trial production for many days, this new product has been officially launched.

　　"After Tianshui Mala Tang is on fire, how can we seize this wave of traffic and continue to undertake this heat to Lanzhou? In fact, we still have to work hard on product innovation." Yang Guoyan said, "Gansu is more delicious than mala Tang, Wuwei ‘ Three sets of cars ’ , Zhang Ye ‘ Stir-fry firecrackers ’ , Longnan stirred up the group … … Longshang cuisine has a long history. How to make use of this mala Tang craze to make all kinds of snacks in Gansu known to more people and promote them to the whole country requires not only the help of the cultural tourism department, but also the joint efforts of the catering industry and other departments. "

　　C "Gansu Mala Tang" online orders skyrocketed.

　　According to the data of Meituan, since March, the search volume of keywords related to "Gansu Mala Tang" has increased by 18.5 times from last month, and the number of public comments has soared by 13.2 times. The take-away orders of Gansu Mala Tang increased 66 times from last month. Beijing, Xi ‘an, Jinan, Shanghai and Tianjin are the top five cities in search volume.

　　At the same time, the popularity of Tianshui Mala Tang has also driven the growth of local cultural tourism consumption. The booking volume of travel orders in Tianshui City, Gansu Province increased by 71.8% compared with the same period of last year. Among them, the order volume of hotels and homestays increased by 73.6% year-on-year, and the order volume related to scenic spots increased by 216.8% year-on-year. Maijishan Grottoes, Fuxi Temple, Maijishan Hot Springs, Xianrenya and Yuquan Temple are the top five scenic spots in terms of order volume. Shaanxi, Henan, Jiangsu, Guangdong, Ningxia, Beijing and Sichuan are the top provinces and cities in the source of off-site orders.

　　On various social platforms, many netizens called for authentic Gansu Mala Tang to be eaten in their hometown, and called on Tianshui people to open stores in their hometown. Some physical stores that see business opportunities are trying to seize the opportunity … …

　　Gansu Beijing Office, located in Beijing Feitian Mansion, has recently put up "Gansu Mala Tang", attracting many netizens to taste the punch card. And a female shopkeeper from Tianshui also decided to open a Gansu Mala Tang restaurant in Sanlitun, one of the hottest business districts in Beijing, which is expected to be officially opened in half a month.

　　On March 19th, University of Science and Technology Beijing issued a document saying that "Gansu Tianshui Mala Tang" will be launched in the school cafeteria at noon. In order to reflect the authenticity, the school emphasized that "soul juice" is all from Gansu, and it brings together two ingredients of Tianshui, namely Gangu pepper and Qin ‘an pepper. The potato powder is elastic and smooth, Gangu chili pepper is full of oil, and the most delicious thing is the intersection of fresh hemp and Qin ‘an pepper. In fact, as early as 2012, the school established a fixed-point assistance relationship with Qin ‘an County, Gansu Province, and purchased Qin ‘an pepper every year. This year, a new potato powder procurement project was added, and the canteen master went to the local area for research and study, bringing students a better experience.

　　Searching with "Gansu Mala Tang" as the key word through Tianyanchao platform, in the past three months, there have been more than 200 new Mala Tang shops in China. Among them, since February this year, there have been more than 150 newly opened Gansu Mala Tang shops in China. According to the data of Tianyancha Professional Edition, up to now, there are more than 9,600 mala Tang related enterprises in Gansu, while there are nearly 900 related enterprises in Tianshui City alone.

　　It’s not the first time that the shady scene has been exposed. The incident of adding sugar in 3.15 exposure must have shocked all car owners. Everyone will wonder if their cars have been added with sugar in a black heart. So what’s the harm of adding sugar to the cake? In addition to adding sugar to the car, what else does the "black heart" S shop add to the car to pit the owner?

　　Event review

　　Ms. Yang from Jingmen, Hubei Province spent 310,000 yuan to buy it. It was the first time to maintain it in a certain place. After more than two hours of delivery, she was told that there was a lot of sugar in the vehicle. Cleaning these sugar must be decomposed, and Ms. Yang had to pay for it at her own expense.

　　Adding sugar can cause "chronic heart disease"

　　White sugar, as a white crystal, will not dissolve in the engine oil, but with the start of the vehicle, the temperature of the cylinder will rise, and the white sugar will slowly melt, which will greatly increase the viscosity of the engine oil, so that it cannot be circulated normally. The damage caused by adding sugar will be overhauled, all oil circuits need to be cleaned and inspected, and parts such as oil pumps and oil pipes that cause blockage need to be replaced. The labor cost and material cost will easily exceed 10,000 yuan. Generally, manufacturers provide a warranty of as short as 3 years/100,000 kilometers and as long as 6 years/150,000 kilometers. As long as there is a problem with normal maintenance, manufacturers will unconditionally repair it. Adding sugar to the car is man-made destruction. If the crime can’t be found, the owner can only bear it himself.

　　The mechanic knows that a car with sugar can run up to 180 kilometers. After they put sugar, they will call the next maintenance department to get ready for that car and introduce business to each other. Overhaul is not a small expense, at least 20,000-30,000 yuan, and the garage will make a profit.

　　Besides adding sugar and black heart, what else is added to the car to damage it?

　　Alcohol in brake oil

　　In addition to adding sugar to the engine oil, some people broke the news that some black-hearted auto repair shops would quietly add alcohol to the brake oil. Adding alcohol to the brake oil will harden the parts in the brake system, thus accelerating the wear of the brake system. Once the owner feels that he can’t stop the car, he has to replace the brake system quickly. It is indispensable to spend thousands of dollars, and the garage will make another profit.

　　Sprinkle salt in antifreeze

　　The antifreeze is added to the water tank. Adding salt to the antifreeze and then adding it to the water tank is a common trick in black-hearted car repair shops. "The water tank mixed with salt will cause scale in the water tank, which will not only cause the circulating water to be unblocked, but also seriously corrode the water tank and cause the water tank to be damaged." The obvious consequence of this move is that vehicles often inexplicably show that the water temperature is high and even the water tank leaks. The repair cost of water tank varies from several hundred yuan to several thousand yuan according to different models.

　　Add bittern

　　After the bittern is added, the salt will agglutinate inside and form a "paste", which, like sand skin, wears away the parts constantly. When the wear reaches a certain level, the grinding disc in the inner part needs to be replaced, and the whole part may be damaged.

　　Under normal circumstances, this process of wear and tear takes a year or even years, but this dirty trick can shorten this process to months or even weeks. The profit is also considerable, and the repair cost is as high as 10 thousand yuan to 15 thousand yuan.

　　Adding caustic soda to the cleaning solution

　　Some stores add caustic soda to the cleaning solution when cleaning the water tank. On the surface, it seems to be cleaner, but it is not. After adding caustic soda into the cleaning solution, it will accelerate the aging of the plastic pad. If you don’t know what’s going on, you have to replace the plastic pad frequently, and put it in for hundreds at a time.

　　In order to avoid this kind of thing, the owner had better choose a reputable and trustworthy repair shop when repairing.

BA.4 and BA.5, the new branches of Omicron with stronger communication power, have recently attracted attention. The new branch has triggered a new infection peak in South Africa, and the Portuguese National Institute of Health also estimates that its growth advantage is 13% more than that of BA.2.

Screenshots from the nextstrain website show that the different Omicron branches represented by yellow, orange and red are iterating rapidly within half a year, and the new branches represented by orange and red are also expanding in the cracks.

Screenshot of nextstrain website. According to the uploaded sequencing data, since December last year, the mainstream branches in Omicron have gradually changed from BA.1 (shown as 21K) to BA.2 (shown as 21L) to BA2.12.1 (shown as 22C), and the area occupied by new branches is also expanding.

The new branches of Omicron are frequent. Is the current COVID-19 vaccine still effective? Do the branches BA.2 and BA.5 need their own vaccines? Should the update of COVID-19 vaccine keep up with the variation of virus? How to keep up with the virus mutation? With the above questions, the reporter of Science and Technology Daily contacted and interviewed a number of industry experts.

Is the current vaccine still effective?

Does the mutation branch in Omicron constantly trigger new infection peaks, which means that the current COVID-19 vaccine will be invalid?

Authoritative experts in the industry responded to the Science and Technology Daily reporter and said: "Current vaccines can still provide the most basic protection in ensuring the reduction of severe illness and death.. The epidemic in COVID-19 has been going on for two and a half years. At present, it seems that there is no possibility for Covid-19 to achieve zero infection through vaccination. COVID-19 vaccine can ensure the effect of reducing infection and avoiding serious illness and death. "

Regarding the role of the current vaccine in epidemic prevention and control, the person in charge of vaccine-related production enterprises in COVID-19 holds the same view: "The existing vaccine is no problem in preventing severe illness and death at present, but it will not be 100% anti-infection."

Many statistics or research results from the real world show that the current vaccine plays a significant role in preventing severe illness and death. For example, the latest data in Hong Kong (as of May 25th) showed that the mortality rate of those infected in Omicron who were not vaccinated was 3.04%, while the mortality rate of those infected with three doses of vaccine dropped significantly to 0.04%.

Do the branches BA.2 and BA.5 all need their own vaccines?

According to WHO’s latest weekly report on epidemiological progress in COVID-19 (May 25th),Omicron BA.2 and its progeny pedigree (BA.2.X) have become the main popular variants in the world.At present, the relative proportions of BA.2.X, BA.4 and BA.5 are 94%, 0.8% and 1% respectively.

This shows that during the evolution of Omicron mutant, the branch BA.1 is disappearing. However, the reporter learned that at present, most vaccines against Omicron in China are designed and developed for BA.1.

Whether it is necessary to develop new vaccines for new branches, the industry generally judges from the perspective of vaccine protection: if the activity of neutralizing antibodies produced by the original vaccines against mutant strains is greatly reduced, it is necessary to develop new vaccines; If it still has a good neutralizing effect on the mutant, there is no need to develop a new vaccine.

Although Omicron strain mutates rapidly and different branches appear, butNew vaccines will not be introduced for each branch, and there is no need to do so.. Relevant experts reminded: "If you continue to monitor, you will find that many mutations will disappear soon."

Can vaccine update keep up with virus iteration?

In the technical route of vaccine development in COVID-19, the design cycle of mRNA vaccine is short. On the basis of a mature platform, the design can be completed within 7 days, and the preclinical trials including animal experiments can be completed in about one month.

Industry experts engaged in the research and development of mRNA vaccine said that for the variant branch, the mRNA vaccine does not need to obtain the strain, but only needs to optimize the vaccine sequence according to the variant sequence and test the expression efficiency, and then pre-clinical trials can be carried out. Covid-19 Omicron mutant mRNA vaccine, developed by Suzhou Aibo Bio, China, has been approved for clinical research in UAE.

In response to virus variation, the technical route of inactivated vaccine can also complete the preclinical study of new strains in a short time by establishing an emergency system. The reporter previously learned that it can be advanced to the clinical trial application stage about 2 months after obtaining the new strain.

Keep up with the variation, can COVID-19’s vaccine market learn from the "flu model"

In order to cope with the frequent mutation of viruses, there are precedents for vaccine updates to follow closely. For example, the influenza virus vaccine is recommended by WHO every year, and countries produce new influenza vaccines accordingly.

In order to keep up with the variation in Covid-19, can the "flu model" be used for reference in the marketing of vaccines in COVID-19?

“It is estimated that the future development of COVID-19 vaccine needs to adopt the influenza model.The authoritative experts mentioned above responded, but WHO is unable to recommend mainstream strains through monitoring now, because the pandemic is not over yet.

Another advantage of the "flu model" is that it greatly shortens the time to market for new vaccines. Because there is no need for re-approval, its batch issuance system can effectively shorten the period from vaccine development to marketing. Experts in the industry said that after polishing and construction, various technical routes and platforms have gradually matured, the research and development speed has been accelerated, and the production process has been stable.If the "flu model" can be adopted in the development and marketing of vaccines in COVID-19, the time to market for new vaccines will be greatly shortened.

WHO has revealed some unexpected phenomena in its weekly epidemiological report: available data show that BA.4, BA.5 and BA.2.12.1 spread faster in countries where BA.1 was once prevalent, but less in countries where BA.2 was prevalent; The vaccination degree of each country may have an impact on the popularity of the new branch of Omicron. Visible,Covid-19 mutation and vaccine immunogenicity are mutually causal and widely related, and updating the vaccine in time may have an impact on virus mutation.
