During the half year of staying at home, have you tried your best for your child’s growth? Bone soup, growth hormone, nutritional supplement, stretching exercise … … Anyone who hears a folk prescription that can be shot up will give it to his own baby to try. However, are these so-called height-increasing tips really helpful for growing taller? Today, let’s take a look at the rumors of the height that are all the rage, and see if you have encountered the following "pits".

　　Rumor, drinking more bone soup can make you taller.

　　Bone is indeed rich in calcium, but it has little to do with calcium supplementation.

　　First of all, calcium in bones is difficult for human body to absorb; Secondly, no matter how long the bones are stewed, the calcium is difficult to dissolve into the soup. We see that the thick white soup is actually mostly fat. Therefore, drinking bone soup for a long time can not only supplement calcium, but also lead to the risk of obesity.

　　Compare the calcium content of bone soup and milk — — Bone soup: 2 mg/100 ml; Milk: 104mg/100ml.

　　The calcium content of milk is far greater than that of bone soup, so it is not as practical as drinking milk to supplement calcium for children and drink bone soup.

　　Rumours: Milk can grow taller when drunk in water.

　　The latest Dietary Guidelines for China Residents (2016) should drink 1,500-1,700 ml of water every day.

　　Protein and fat in milk are about 3%, sugar content is about 5% and calcium content is about 1%. If you drink milk according to this amount, the supply of calcium will be excessive, and the fat and energy will be much higher. Even if you drink half the milk you drink every day — — 800 ml, intake of fat and energy.

　　In addition, drinking milk as water will lead to excessive intake of protein in the body. Too much protein supply, the human body can’t "take it all", but the absorption rate will drop.

　　The daily consumption of milk should not exceed 500ml. Moreover, drinks such as fruit juice, carbonated drinks, functional drinks, AD calcium milk and other milk drinks should not be drunk, let alone used as daily water.

　　Rumours that Tianqi soup can grow taller.

　　In recent years, "Tianqi" has been sought after by many health people, and the fact that Tianqi can help children grow taller has become a concern of parents. At present, there is no scientific evidence to prove that the folk remedies of "Tianqi stewed chicken, Tianqi stewed ribs and Haima stewed Tianqi" can be safely and effectively increased. Moreover, these traditional Chinese medicines and tonics may have the risk of accelerating the closure of the epiphyseal line, which will lead to lifelong high damage and even endocrine diseases such as precocious puberty!

　　At the same time, herbal tea with Chinese herbal medicines is not suitable for children to drink more and often. Some nutrients fortified in packaged foods, such as milk and yogurt fortified with vitamin ad and calcium, and beverages fortified with vitamin C, iron and zinc, such as electrolyte drinks such as red bull, candy, bread, eggs, etc., should also look at the content when choosing, and calculate the need, otherwise it will go too far.

　　In addition, there are adult-formulated health care products such as pollen and royal jelly, which are also very risky for children to eat.

　　There was a five-year-old girl who ate pollen and royal jelly for several months in a row. Instead of growing taller, her breasts began to increase and her bone age reached nine years old. Children with precocious puberty will not be "superior", but will lead to early healing of epiphyses, and eventually lose the space for growing up and become "dwarfs".

　　Blame rumors and eat growth factors to grow taller.

　　Malnutrition does affect height, but the nutrients that are very easy to get in natural foods really don’t need to be supplemented with supplements. When you get some nutrition through natural food, you can also get many other nutrients that can promote growth. In recent years, various growth factors with lysine as the main component have become new nutritional supplements. It is said that eating it can promote healthy growth, calcium absorption, appetite and so on.

　　Lysine is an essential amino acid for human body. Like other amino acids, it can be obtained through daily diet. The statement that manufacturers sell lysine supplements is nothing more than that the lysine content in grains is very low, which can not meet the needs of human body.

　　We Asians’ traditional staple food rice does lack lysine, but there are many other foods rich in lysine to choose from, such as lean beef, pork, chicken, fish, shrimp, nuts, eggs, beans and legumes.

　　Instead of blindly buying expensive nutritional supplements, it is better to think of ways to give children these foods mentioned above.

　　Dispelling rumors and eating nutritional supplements are beneficial to development.

　　It is unnecessary for most parents to give their children supplements, such as vitamin C, calcium, zinc, etc., which are very easy to get from food. If the child’s long-term uneven diet has caused a serious lack of certain nutrients and caused diseases such as anemia and vitamin D deficiency rickets, it must be supplemented according to the doctor’s advice. Other conditions, including mild nutritional deficiency, can be supplemented by dietary adjustment, and should also be supplemented by dietary adjustment.

　　Slight nutritional deficiency can be slowly improved by dietary adjustment. For children themselves, life has not passed for a few years, and it is easy to improve through diet adjustment without the conditions of "long-term" lack.

　　Short-term and slight nutritional deficiency will not cause any problems. On the contrary, it may be because of parents’ efforts to develop good eating habits for their children and form a balanced diet structure, so that children can benefit for life.

　　Dietary supplement is the safest and most effective method.

　　Myth: Stretching and draping can grow taller.

　　For patients with hunchback and scoliosis, spinal traction can also help restore a certain height.

　　See it clearly? Recover!

　　To put it simply, after stretching exercise for a period of time, the interosseous tissue returns to a better thickness, and the measured height value will increase a little. However, such stretching is not the height of the child’s own long bone growth. If it is not stretched properly, it will easily cause muscle damage to the child.

　　I would like to remind everyone here that reasonable exercise is conducive to balancing the growth of bones and the metabolism of calcium and phosphorus in the whole body, and promoting the physical development of children. Pay attention to the exercise that can make the bone bear pressure, which is the best stimulus to promote bone growth.

　　I recommend the following sports:

　　● Including skipping rope and running, which is beneficial to the movement of limbs;

　　● Sit-ups, gymnastics and other sports that contribute to bone growth;

　　● Volleyball, badminton, swimming and other comprehensive sports all contribute to the growth and extension of the whole body bones.

　　However, it is particularly important to emphasize that we must stretch well to avoid the damage of joint ligaments. If children want to really grow up healthily, it is a better choice to exercise continuously for at least 4 to 5 days and ask for 30 to 45 minutes at a time. In addition, let children choose sports according to their age and interests, and carry out physical exercise under the premise of safety, which must be gradual.

　　CCTV Finance reported on July 20 that in recent days, the phenomenon of vaccine shortage has appeared frequently. Just two days ago, the Shenzhen Municipal Center for Disease Control and Prevention said that the first-class vaccine gap in Shenzhen reached 175,000, and in Guangxi, many parents who vaccinated their children also suffered from vaccine shortage.

　　CCTV Finance "Economic Information Network" column video (01:35)

　　Ms. Long, a citizen of Nanning, Guangxi:DTP has not been vaccinated since May 8th, and now it is more than July 10th. There is no vaccine yet. Originally, four shots were given, but now only two shots have been given.

　　Ms. Long has an eight-month-old child. She should have been vaccinated with the third DTP vaccine in May, but she was delayed for two months, which made her a little worried. There are many parents who have the same experience as Ms. Long.

　　Citizens of Nanning, Guangxi:DTP is free and out of stock.

　　Citizens of Nanning, Guangxi: at my own expense. We waited too long, and the doctor said we didn’t know when it would be available, so we had to call first.

　　According to Guangxi Center for Disease Control and Prevention, there are five kinds of vaccines, namely, leprosy vaccine, measles vaccine, DTP vaccine, hepatitis A vaccine and Japanese encephalitis vaccine, which are currently lacking in Guangxi. Among them, the supply rate of leprosy vaccine with the biggest gap is less than 20%.

　　(1) Leprosy vaccine. Since January 1, 2019, the supply rate in Guangxi has been 19%, and the supply has been insufficient since July 2018.

　　(2) DTP vaccine. Since January 1, 2019, the supply rate in Guangxi has been 32%, and the supply has been insufficient since July 2018.

　　(3) measles vaccine. Since January 1, 2019, the supply rate in Guangxi has been 59%, and the supply has been insufficient since January 2019.

　　(4) Hepatitis A vaccine. Since January 1, 2019, the supply rate in Guangxi has been 72%, and the supply has been insufficient since January 2019.

　　(5) Japanese encephalitis vaccine. Since January 1, 2019, the supply rate in Guangxi has been 60%, and the supply has been insufficient since January 2019.

　　The person in charge of the Guangxi Center for Disease Control and Prevention said that the above-mentioned vaccine shortage is nationwide, mainly because the production capacity of production enterprises is insufficient, and there is no sign of improvement in supply in a short time. These shortages of class I free vaccines can be replaced by self-funded class II vaccines.

　　Zhong Ge, Director of Institute of Immunization Planning, Guangxi Center for Disease Control and Prevention:Newborns have received one or two injections of the first-class vaccine, but if they have not completed the immunization procedure, they can use the second-class vaccine instead of the later injections, which can also achieve the effect of immune protection.

Produced jointly by Wenhuaren (Beijing) Culture Media Co., Ltd. and Fengxing Online, the highly anticipated short play "Clouds Going Up" will be officially launched on May 10th. With its unique world outlook of coexistence of ancient martial arts civilization and modern civilization, the play has attracted a large number of audiences’ attention. In this work, Shi Fei Da, a powerful actor, will play Wen Yu, the eldest brother of the three brothers and sisters of the Wen family, which has attracted strong attention from fans.

Shi Feida, who is 178cm tall and weighs 65kg, has a handsome appearance and unique temperament. He is a versatile actor with rich acting experience. As early as 2010, he partnered with Ni Ping, a famous actor and host, to host the Third China Artists Awards Ceremony in world artists association, USA, and won the Best Newcomer Award. This honor not only affirmed his hosting talent, but also predicted his infinite possibilities in the future.

While at school, he was lucky enough to participate in the film Far away Xilin Gol directed by the famous director Gao Feng, and he played Guo Qinglin (first hero), an educated youth in Beijing, and accumulated valuable performance experience. After graduation, he devoted himself to the shooting of many main melody films, constantly challenging himself and improving his acting skills.

In the anti-Japanese war film Sun Face directed by Xinyun Zhu in 2013, Shi Feida played Zhou Maosong, and his superb acting skills and solid lines were widely recognized in the industry. Whether it is the emotional expression of the role or the interpretation of the action play, he has shown excellent professionalism and acting talent.

In addition, Shi Feida’s performance in the film field is also quite eye-catching. His film works include Strange Crime, Qian Xuesen, Far-off Xilin Gol, Lost, Music and Whose Child. In these works, he created many characters with different personalities and distinct images, which showed his diversity and plasticity as an actor.

In the upcoming short play "Clouds Going Up", Shi Fei Da will play Wen Yu, the eldest brother of Wen Ji’s family, which is a role full of sense of justice and responsibility. In Yun Kaminooji, a world where ancient martial arts civilization and modern civilization coexist, he will lead his younger brothers and sisters to protect ancient martial arts civilization, maintain modern order and present a legendary heroic image for the audience.

Shi Feida said that he was very excited and looking forward to playing such a role. He believes that the story background and role setting of "Up in the Clouds" are very attractive, and he will devote himself to shaping the role and bring a brand-new and unforgettable performance to the audience. With the upcoming launch of Clouds Going Up, the audience are full of expectations for Shi Feida’s performance in the play. I believe that he will bring a double feast of vision and mind with superb acting skills and profound performance skills.

"Clouds Going Up" is not only a wonderful short play that combines ancient martial arts civilization and modern civilization, but also a masterpiece that shows the brilliance of human nature and heroic feelings. With the participation of many outstanding actors such as Shi Fei Da, the play will surely become the focus of the audience’s attention. Let’s look forward to the arrival of May 10th and witness the wonderful performance of Shi Feida in Clouds Up.

　　German scientists have discovered a magical chameleon subspecies in northern Madagascar. They are only the size of melon seeds and can lie on human fingers, which may be the smallest reptile on the earth.

　　The Bavarian National Zoo in Munich, Germany, said that they found two adult miniature chameleons, a female and a male, in northern Madagascar. Among them, the male is only 22 mm long, which is the smallest known reptile. The other female chameleon is a little bigger, but the total length is only 29 mm.

　　The researchers said that it is not clear why the species is so small, but perhaps similar to the "island effect", animals trapped on the island and with small habitats tend to evolve smaller bodies.

　　However, the living environment of this new species is worrying. The habitat of this chameleon has been destroyed by deforestation. Fortunately, in recent years, the government has planned a protected area in the local area, so they are lucky to survive.

　　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."

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.
