WHO calls for a new Covid-19 vaccine – VnExpress


The WHO called for the development of new vaccines with greater resistance to infection, saying multiple booster doses of existing vaccines was not a sustainable strategy.

“The vaccination strategy based on repeated booster doses of existing vaccines does not appear to be appropriate or sustainable,” said the World Health Organization (WHO) advisory group on Covid-19 vaccine preparations ( TAG-Co-VAC) issued a statement on January 11.

TAG-Co-VAC calls for adjusting existing vaccines to enhance effectiveness against raging strains, such as the Omicron strain that has spread rapidly and appeared in 149 countries and territories.

According to WHO experts, it is advisable to develop a new vaccine that is not only able to protect the injector from the risk of severe disease, but also protects the injector from the risk of virus infection more effectively.

TAG-Co-VAC believes that this vaccine will reduce community transmission and help relax strict and widespread anti-epidemic measures. The WHO expert also suggested that manufacturers develop vaccines that “generate good and long-lasting immunity to reduce the need for consecutive booster shots”.

According to WHO, 331 vaccine candidates are being studied around the world.

TAG-Co-VAC added that until a new vaccine is developed, existing Covid-19 vaccines may need adjustment. “This is to ensure that vaccines continue to provide protection to the injector from the risk of infection and progression from the strains of concern, such as the Omicron strain and later strains,” TAG-Co-VAC said. confirm.

WHO has approved nine Covid-19 vaccines. TAG-Co-VAC emphasizes that these vaccines are still highly effective in preventing the risk of morbidity and mortality from these strains.

Figures from AFP shows that more than 8 billion doses of Covid-19 vaccine have been administered in at least 219 countries and territories. According to United Nations figures, while more than 67% of people in high-income countries have received at least one dose of the Covid-19 vaccine, the figure in low-income countries is less than 11%.

Virus making copies in the throat, this is the main reason for the rapid spread of Omicron


Omicron Fast Spreading: You know very well that Omicron is spreading much faster than any other variant of Corona. Even the scientists themselves are surprised to see the speed of its spread. As always, WHO is constantly sharing guidelines and new information regarding this variant of Corona.

  • Recently, WHO technical head Maria van Kerkhove gave information on why Omicron is spreading at such a high speed. The first and main reason for this, Maria told that the mutations in the new corona virus Omicron are helping it to easily connect with the cells of the human body.

You will remember that when Kovid-19 started, a lot was said at that time that the virus is rapidly damaging the cells in an attempt to connect with the human cells. Although Omicron is such a developed virus that it is easily pairing with the cells of the body.

  • Maria gave another reason that this virus is being successful in brightening the immune system. This is the reason that people who have had an infection before, it is also making them their victims. Also, people who have taken both the doses of the vaccine are also not able to escape from its grip.
  • The third reason is that Omicron is affecting the upper respiratory tract and is replicating here. That is, this virus is making other viruses like itself (its copies) by taking control of the upper respiratory system. This is also a major reason for the spread of this virus. Whereas other viruses of the corona replicate in the lower respiratory tract or lungs.

That’s why it is important to avoid Gathering

If we look at all these three symptoms of Omicron, then it becomes clear that more interaction, exposure to more people and spending more time outside the house can prove to be harmful. This is the reason why health experts are constantly appealing to people to stay at home. Also advising to avoid parties.

AI can ‘rescue’ businesses from cyberattacks


AI can build network defenses, detect malware, and warn against attacks by hackers.

A hacker can break into an organization’s internal network and steal important data assets in less than 20 minutes. By the time a business discovers malicious activity, it’s too late. That’s where AI comes into play.

The growing security threat makes companies like Microsoft, Huawei deploy AI for their cybersecurity strategy. “We’re seeing an incredible increase in the number of attacks, from ransomware to various types of zero-day attacks,” said Ann Johnson, VP of security at Microsoft. , said.

According to him, the complexity of modern attacks makes it completely impossible for humans to keep up. Therefore, companies must apply AI to deal with threats, help detect unusual behavior early, and take automatic measures to prevent intrusions as quickly as possible.

At the Tokyo 2020 Olympics, the Darktrace AI tool detected a malicious Raspberry Pi IoT device that was installed in the office of a sports authority of a country participating in the Olympics. The AI ​​system noticed that the device was scanning for nearby devices, so it blocked the connection, sending an alert to analysts.

“Too much digital data is created in 2021 and beyond. You have to use intelligent AI to track attacks. Otherwise, an attacker can take control of the system in real time. for a long time,” said Mike Beck, Darktrace’s chief information security officer.

Mika Lauhde, Huawei’s Global Vice President of Security, affirmed that AI is playing an important role in ensuring network security, especially in the digital transformation trend.

According to him, the accumulation and use of big data and improvements in machine learning methods have helped AI technology to make great progress in image recognition, speech, natural language processing, thereby influencing the future. significantly to security. On the one hand, AI is used to build defenses, detect and warn against cyber attacks. On the other hand, AI can also be exploited to create attacks and manipulated by hackers with malicious intent.

“When it comes to AI, it is necessary to define the difference between Artificial Intelligence (AI) and an Artificial Intelligence System (AI system). AI displays intelligent behaviors by analyzing data proactively and proactively. gives certain feedback to achieve a specific goal, while AI system is software that is developed from a variety of techniques and approaches towards a set of human-defined goals. definitions of AI, we will easily control and identify protection options when deploying AI application systems,” he said.

Huawei also proposed three layers of AI system protection including data-based attack mitigation with defense mechanism design, verification security model, and enhanced robustness of security mechanism, and security architecture, building a safe system architecture to defend and ensure security.

The application of AI in security is expected to grow exponentially in the coming years. According to Market Research Engine, the AI ​​cybersecurity market is expected to reach $35 billion by 2024.

WHO does not know the severity of the strain Omicron


The WHO said on November 28 that it was not clear whether the new strain of Omicron was more likely to spread or make the disease more severe than other strains.

“Preliminary data suggest an increasing rate of hospitalization in South Africa, but this may be due to an increasing total number of infected people, and not to a specific strain of Omicron,” a statement from the Foundation said. The World Health Organization (WHO) has paragraphs.

However, WHO reiterates that there is evidence that there is a higher risk of reinfection from this variant.

WHO says it is working with experts to understand the potential impact of the Omicron strain on current responses to Covid-19, including vaccines.

“Currently, there is no information to show that the symptoms associated with Omicron are different from those in other strains,” the WHO said. “The initial reported infections were among those from the university, but understanding the severity of the Omicron variant takes days to weeks.”

The PCR test can detect the Omicron strain, and studies are ongoing to determine whether rapid antigen tests are affected, WHO notes.

The Omicron mutation, which first appeared in South Africa, is causing global concern. A series of countries have applied measures to tighten entry and exit and isolate and test people returning from Africa.

From November 29, the US and the European Union (EU) began to ban flights from South Africa and surrounding areas. Four Southeast Asian countries including Malaysia, Thailand, the Philippines and Singapore have tightened travel with southern African countries, requiring quarantine of people entering the country in the past few days.

The UK also banned entry for people from South Africa and five neighboring countries. Similar moves have been made in Australia, Japan, India, Iran, Brazil and Canada.

WHO accuses rich countries of prolonging Covid-19


WHO officials criticized the situation of rich countries collecting vaccines and drugs to treat Covid-19 causing the pandemic to continue to develop complicatedly around the world.

“This situation is not only unjust and unethical, but it also prolongs the pandemic, causing deadly consequences,” said epidemiologist Maria Van Kerkhove, the WHO’s Covid-19 technical team leader. (WHO), emphasized in the online press conference on September 7.

According to a WHO report, Africa has only received two doses of the Covid-19 vaccine for about 3% of the continent’s population. At the current rate of vaccination, about 80% of African countries in September will not be able to protect the 10% of the population most at risk of infection.

Mike Ryan, director of the WHO’s health emergencies program, criticized high-income countries for not acting on their claims of ensuring equitable access to vaccines. “In fact, in a difficult situation, medicine is collected into the hands of a few countries and not shared,” he said.

According to statistics from the Center for Systems Science and Engineering (CSSE) of Johns Hopkins University, as of September 8, the world had recorded 221,706,278 cases of nCoV infection, including 4,582,737 deaths. confirmed death. In the past 28 days, the world has increased by more than 17.8 million infections and more than 273,000 deaths.

A report from data research firm Airfinity shows that global production of Covid-19 vaccines reached 6.1 billion doses as of the end of August. The company estimates global vaccine production per month at 1.5 billion doses and total volume. World vaccine by the end of this year is likely to reach 12.2 billion doses.

Most vaccines are concentrated in rich countries. G7 members, including the UK, Canada, Germany, France, Italy, Japan and the US, have more than 300 million doses of Covid-19 vaccine left over and are expected to stockpile 1.2 billion doses before the end of the year.

At the beginning of August, WHO asked rich countries to delay the booster vaccination plan for at least two months, shifting the source of the vaccine to poor countries that are threatened by the Delta mutation. However, the booster injection plan is still being implemented in the US, UK and France.

In China, the government has deployed more than two billion doses of the Covid-19 vaccine with about 67% of the population having received two doses. The National Health Commission (NHC) estimates 1.09 billion people have received at least one dose of the vaccine. The national vaccination program is accelerating with the population aged 12 to 17, aggressively building “immunity barriers” in the community.

After the Delta outbreak in July with more than 1,300 infections in 15 provinces, China continued to successfully control community transmission with strong measures. NHC on September 7 recorded 36 more symptomatic infections nationwide and no suspected cases. As of September 7, the country has 95,064 infections and 4,636 deaths from Covid-19.

Japan recorded positive signals in controlling the fourth wave of Covid-19 when the number of weekly infections tended to decrease. The number of new infections on September 7 was 1,629, an increase of nearly 500 cases compared to the beginning of the week but a sharp decrease compared to the number of 2,909 infections 7 days ago.

However, the epidemic situation in Japan in general is still complicated. The capital Tokyo and some localities have the ability to extend the state of emergency after the deadline on September 12. The tough measure was applied in 21 provinces. The European Union (EU) is considering putting the country on a list of travel restrictions to prevent Covid-19 risks.

America continues to be the country most severely affected by the pandemic with more than 40.2 million infections and more than 651,000 deaths in nearly two years. Although about 53% of the US population is fully protected by vaccines and more than 1.3 million people have received booster shots, the number of deaths and infections in the US has skyrocketed in recent days because of the Delta mutation.

Health officials in this country are more concerned when 49 out of 50 states have detected the Mu strain that is contagious in the community. The new strain is said to be more resistant to the effects of the vaccine than the recent mutations of nCoV. The state of California has the highest number of Mu mutant infections in the country, most of which are concentrated in the city of Los Angeles.

In Southeast AsiaAs of September 7, the whole region has more than 10.6 million infections and more than 216,500 deaths, according to statistics from the Center for Strategy and International Studies (CSIS). The three epidemic regions with the most infections in the region are Indonesia with more than 4.1 million cases, the Philippines with more than 2.1 million cases and Malaysia with more than 1.8 million cases.

Indonesian President Joko Widodo on September 7 called on people to recognize that Covid-19 will persist despite the country’s improvement in disease control. From August 31 to September 5, Indonesia recorded 49,753 new infections and 3,370 deaths, down more than 21,000 infections and nearly 1,000 deaths compared to the period from August 25 to 30.

Elon Musk’s humanoid robot is controversial


Some tech experts think that Elon Musk is flaunting the Tesla Bot model because developing a humanoid robot is unlikely to be completed in a year.

On August 19, Elon Musk announced the Tesla Bot project during the company’s AI Day event. Many people are optimistic, believing that Tesla Bot will change lives in the future and is a product worth looking forward to. However, others doubt Musk’s robot project is just a joke.

Tesla’s robot was introduced by Elon Musk during the “AI Day” event on August 19. Video: Tesla

Musk’s post about Tesla Bot on Twitter received great attention. The video introducing the robot alone attracted 1.5 million views, 43,600 likes, 9,600 shares and 4,300 comments. Among them, a Twitter account asked Musk if robots like the Tesla Bot would be mass-produced and sent to Mars. Musk replied succinctly: “I hope so.”

Meanwhile, according to The Verge, to consider the possibility that Tesla Bot may launch next year as Musk said, can take Boston Dynamics as a reference. This is the world’s most advanced robotics company with Atlas – a humanoid robot designed for search and rescue missions, announced in July 2013. After eight years, Atlas is still not commercialized.

Carl Berry, lecturer in robotics engineering at the University of Central Lancashire (UK), says: “I’m not against Musk working in this area, but it’s not good to be hyped like that.”

Berry emphasized that developing an AI robot in manufacturing often requires making a machine as simple as possible, not the most complex as Musk is doing with the Tesla Bot. He said that Tesla producing humanoid robots within a year is difficult to come true.

Some experts believe that Musk’s introduction of this robot model at the AI ​​event is just a “magic” to distract the public from the recent scandals related to Tesla’s self-driving car system.

“I can say for sure, it will be more than 10 years before a humanoid robot, manufactured by any company, can go to the grocery store and shop on its own,” said Raj Rajkumar, a professor of engineering. electricity and computers at Carnegie Mellon University, USA told Reuters.

According to Musk’s description, Tesla Bot is about 172 cm tall, weighs 56 kg, is made of lightweight materials, can travel at a maximum speed of 8 km / h, carries 20 kg of goods, lifts 68 heavy objects. kg. The robot’s head integrates the camera used in Tesla electric vehicles, allowing it to sense its surroundings and a screen to display information.

Basically, this robot is operated by the same AI system on Tesla’s electric car. The Tesla CEO said the robot was designed to be “friendly and navigable in a world built for humans” and to fill the void left by labor shortages.

Error in WHO-China joint investigation report cáo


The US newspaper discovered the first Covid-19 patient record inconsistency in the joint investigation report and WHO said this was an “unintended error”.

The World Health Organization (WHO) confirmed the first Covid-19 case as patient S01, a 41-year-old man, with viral genome sequences EPI_ISL_403930, MT019531 and GWHABKH00000001 in different databases. However, a joint investigation report on the origin of Covid-19 between WHO and China lists another genome sequence, belonging to a 61-year-old man.

The Washington Post of the US discovered this contradiction and sent a question to the WHO. The organization acknowledges this as an “unintended error” and will correct it and consider the possibility of further errors.

WHO did not explain why a map in the WHO-China joint report appendix appears to show the first case recorded on this side of the Yangtze River, while Wuhan authorities last year reported the patient. first showed symptoms on December 8, 2019, lives on the other side of the river, in Wuchang district.

The WHO-led investigation team went to the Wuhan Institute of Virology, China to examine the origin of Covid19 in February. Photo: Reuters.

Tarik Jasarevic, a WHO spokesman, said the agency could not comment on what Wuhan authorities announced last year, but the question of where the first patient lived was not related to theories of origin. Covid-19. According to him, this issue is not important because “up to now, the first patient recorded is probably not the first case”.

Jasarevic said that the errors in the report were due to “correction errors”, but they did not affect “data analysis nor conclusions”.

China’s National Health Commission and the Wuhan Center for Disease Control and Prevention did not immediately respond to requests for comment.

It is unclear whether these points can help researchers understand what happened in Wuhan. However, editing the data a few months after the report’s publication and in the second year of the pandemic could turn the question of why understanding the pandemic’s origins has been slow and complicated.

“We need more explanation about the source of the error and the information,” said Lawrence Gostin, a professor of global health law at Georgetown University who provides technical assistance to the WHO. “Who made the mistake? China, the investigation team or the WHO itself? Nothing is clear, and this makes the public not trust the integrity, rigor of the origin investigation.”

Jasarevic said WHO is investigating why the official database of the National Genomics Data Center of China (NGDC) shows that patient S01 started showing symptoms on December 16, 2019, one year later. week compared to the date of December 8 as recorded in the WHO report.

The lack of clarity on patient S01 leads to the possibility that the earliest Covid-19 case recorded could be someone else, with the WHO report mentioning the seafood seller at the Huanan market and others starting to show symptoms. before December 16. WHO also stated that the first family cluster in Wuhan did not come into contact with the Huanan seafood market. Previous reports give conflicting information about the family’s connection to the market.

According to Jasarevic, the viral genome sequence will also be corrected for the other two patients in the report. S05 is a 61-year-old male deceased, with the sequence EPI_ISL_403928, and S11 is a 52-year-old woman with the sequence EPI_ISL_403929.

WHO says nearly a billion doses of G7 vaccine is still not enough


WHO praised the contribution of 870 million doses of Covid-19 vaccine by G7 countries, but said that more vaccines are still needed at a faster rate.

“This is a huge help, but we still need more vaccines and we need to deliver them even faster,” World Health Organization (WHO) Director-General Tedros Adhanom Ghebreyesus said at a press conference on June 14. mentioned the G7 group’s plan to expand the production of Covid-19 vaccines to provide 870 million doses to the world through sharing and funding programs.

The WHO director-general said that there are still many areas that need to be provided with a Covid-19 vaccine as soon as possible, adding that every day about 10,000 people die from the pandemic and critical patients in Africa have a high mortality rate. much higher than the world average.

US President Joe Biden last week pledged to contribute 500 million doses of the Covid-19 vaccine to 92 low- and middle-income countries through the COVAX mechanism, of which 200 million doses will be delivered by 2022.

British Prime Minister Boris Johnson said on June 10 that the country would fund at least 100 million doses of a Covid-19 vaccine, with 5 million starting in the coming weeks. European Union (EU) members have agreed to fund at least 100 million doses by the end of 2021, with France and Germany each pledging to provide 30 million. French President Emmanuel Macron called on pharmaceutical groups that produce vaccines to donate 10% of production to poor countries.

The successive pledges come amid growing calls for rich countries to do more to share vaccines with the rest of the world. However, observers say the effort so far has been a “salt in the water” and the world needs more, while some humanitarian organizations warn that vaccination inequality will lead to ” vaccine racism”.

The COVAX initiative is supported by WHO and the Global Alliance for Vaccines and Immunity (GAVI). The program aims to secure 2 billion doses of the Covid-19 vaccine this year, providing 30% of the population in the 92 poorest countries and territories participating in the program, but is facing many difficulties due to tight supply. rarity, inequality and distributional delays.

DGHS Guidelines: Should children below five years of age wear masks, know the guidelines of the Ministry of Health


Children are feared to be the most affected in the possible third wave of Corona. However, according to AIIMS, there is no strong evidence that the coming wave will have the biggest impact on children. Despite this, people are scared and cautious about their children. Now a guideline has been issued by the Directorate General of Health Services (DGHS) under the Union Health Ministry.

According to this guideline, children below the age of five are not required to wear a mask. Apart from this, the government also issued guidelines for children aged 6 to 11 years. According to this, children aged 6 to 11 years should wear a mask under the supervision of a parent. Earlier, the World Health Organization (WHO) had made it mandatory for children above 12 years to wear masks in its guideline. The WHO had also said that children below 5 years of age do not need to wear masks.

Remdesivir is not for children below 18 years of age
The DGHS also told in another guideline that children below 18 years should not be given Remdesivir injection at all. The DGHS said that there is no concrete data about Remdesivir yet, so this injection should not be given to children. The DGHC advised that if the child does not have symptoms of corona or has a minor infection, then he does not need to be tested. Also, there is no need to give any medicine to such children from their mind. In this situation, the doctor should be consulted through telecommunication and not the hospital. Apart from this, children should be given a nutritious diet and follow the Kovid protocol.

children need extra care
Doctors say that this guideline is necessary for the parents of the children as well as the doctors. According to a report published in the English newspaper, Dr Gauri Agarwal of Yashoda Hospital in Delhi said that it is important to understand the basic information about masks and hygiene. It is impossible for children to understand how to wear a mask. Therefore, DGHS has advised children not to wear masks. Doctors say that since the child cannot wear a mask, parents need to take extra care of their child. A few days ago AIIMS Director Dr Randeep Guleria had said that there is no strong evidence of the maximum impact on children in a possible third wave.

Eat 5 grams of salt a day to stay healthy, WHO’s new guideline


Health Tips: If there is no salt in the food then the taste gets spoiled. But if there is too much salt in the food, it also spoils the taste of the food. Salt is also good for our health but eating the right amount is very important. If you eat more salt then it can be harmful for your health. Now the World Health Organization i.e. WHO has released new guidelines regarding salt in food. In which it is said that in order to be healthy, a person should eat only 5 grams of salt a day. Although most people use twice as much salt in their food. Let us know how important salt is for health. & Nbsp;

Balance of sodium and potassium required

WHO has prepared a global sodium benchmark for sodium level in food for sodium levels all over the world, in which more than 60 food categories have been included to save the lives of people. New standards have been made regarding sodium in these foods. It is estimated that by 2025 the consumption of salt in the world will be reduced by 30 percent. & Nbsp;
In fact, it is necessary to have a balanced amount of potassium and sodium in our body. If there is more sodium in the body with less potassium, then it can harm health. Using more salt in food increases the risk of blood pressure, heart problems and stroke. Eating too much salt also weakens bones. & Nbsp;

These products increase the amount of salt in the body rapidly

It is very important to eat salt to keep the body fit. Salt is necessary to make healthy plasma and keep the nerve healthy. But by eating many things, the amount of salt in our body starts increasing rapidly. Processed food such as packaged food, dairy and meat products, processed food, spices and salt are also high in salt. & Nbsp;

Advantages and disadvantages of salt

We all know that salt is necessary for our body. This keeps our body active. Our body stays hydrated with salt. & nbsp; In addition, salt is also helpful in correcting the thyroid. People who have low blood pressure get relief by eating salt. Salt also improves the symptoms of cystic fibrosis.

Now let’s talk about the harm caused by eating too much salt. Excess salt increases the risk of heart diseases. Excessive intake of salt increases the chances of stroke, high BP and kidney disease. & Nbsp;
