WHO says there may be a vaccine showing efficacy before the end of the year, when will it be adminis

The WHO said that there may be a vaccine before the end of the year to show efficacy, which is just to say that it is possible, and it is not sure that it really is, and the vaccination is even more far away, because the vaccine will have to go through a long period of clinical trials before it can be inoculated into the human body.

Probably next year. After the efficacy comes out, we still have to explore ***, and we have to produce, and it takes time.

At least until the end of the year, because vaccines also need to be in clinical trials.

Is our two-shot vaccine still effective? Because most of the priority vaccinations this time are high-income countries, and many countries have begun to start the third shot, this also makes many people have an idea, those rich countries have gone to get the third shot, so the third shot is useful, and we have two shots, is it useless? In fact, so far, the protective effect of two shots on the epidemic is already very high, and why are there breakthrough cases?

Even if you get the third booster shot, there will be a possibility of breakthrough cases, so the most important thing now is to control the overall situation of the epidemic, so everyone should be calm and wait for the arrangement.

It's because some countries are not developing very well, they simply can't develop a vaccine on their own, and it may put pressure on the country, so it's stopped now.

Because there are only a limited number of vaccines available now, and many countries don't have vaccines yet, we are reducing booster shots and making them available to other low-income countries.

Because vaccines are very limited, vulnerable groups should be vaccinated first, so as to strengthen their physical fitness and reduce the risk.

WHOHe said that the third booster dose is not recommended now, and there are many reasons, and he summarized two reasons. One is that there is a big difference in the penetration rate of vaccines now, between developed and developing countries.

There is a big difference between rich and poor countries, and the other point is that there is not enough data to support the pilot of the third dose of the vaccine itself. <>

The first point is that most of us ordinary people don't think about this, because in our world, our vaccination work started very early, and now many people in the country are getting vaccinated.

is a choice, not a necessary need. This means that I want to have a few vaccines at any time, but whether I think about it now is my personal problem, and we are like that, because our vaccine production is very sufficient, and when we were developing vaccines, we concentrated all our human and material resources. Everything that can mobilize resources to prioritize vaccine research and development, vaccine production, so our vaccine progress is very fast, and the rollout is also very fast, but not all countries are like that.

Rich countries themselves are now vaccinated at more than 50 percent, but poor countries, especially many developing countries in Africa, have a vaccination rate of around 1 percent. This is not enough at all, the vaccination rate must be at least 50%, or even 60% to form a vaccine line of defense, to form a herd immunity effect, we are now gradually developing in this direction, because we are now vaccinating quite fast, **sufficient, you want to do this at any time. But many poor countries and developing countries abroad have not been able to do this, because they do not have vaccines and no money to import, and they cannot afford to develop them themselves.

Another point is what is the effect of the third dose of the vaccine now, it is not sure that there is not enough data to support it, and the validity period of the two-shot vaccine is now 16 months to 12 months after a year, whether there is a need for this third vaccine, the opinion given now is uncertain. However, it is a high-risk group that may have a higher chance of being exposed to the virus, and it is necessary to get the third dose of the vaccine. When to get vaccinated?

This has not yet been determined.

In some places, people are very short of vaccines, and the number of vaccines is not very sufficient, so it is necessary to vaccinate people in these dangerous areas first.

Because the current vaccine penetration rate is still relatively poor, these vaccines should be given to some areas without vaccines, so that everyone can have a defense.

The anti-epidemic measures adopted by various countries include: a laissez-faire strategy to allow the spread of the new crown among the entire population and achieve universal immunity; Lockdown policy, strict implementation of epidemic prevention and control, and control the new crown in a certain area; Vaccine**, vaccine-dependent**; Abandon measures and adopt an "ostrich" policy against the coronavirus.

In Japan, you can't go in and out of shopping malls without wearing masks, they also have something like a health code, and restaurants can't dine-in. Spitting is not allowed in Singapore, and there are rewards for reporting not wearing a mask. These are all foreign epidemic prevention measures.

He called on the people to pay attention to hygiene, try not to go to places where people gather, and wear medical masks when going out.

It is necessary to strengthen epidemic prevention measures, to actively vaccinate, to wear masks when going out, to maintain social distancing, and to address the unequal distribution of vaccines around the world.

The World Health Organization (WHO) has granted emergency use listing to China's Sinopharm vaccine, which means that China's COVID-19 vaccine has a certain safety and efficacy.

1: China's new crown vaccine included in the "emergency use list" The World Health Organization announced on the 7th that the new crown inactivated vaccine developed by the Beijing Institute of Biological Products of China Sinopharm Group has officially passed the WHO emergency use certification and has become the sixth new crown vaccine included in the World Health Organization's emergency use list. The five new crown vaccines that have been included in the emergency use list are the new crown vaccine jointly developed by Pfizer in the United States and the German biotechnology company, the two versions of the AstraZeneca vaccine jointly developed by AstraZeneca Pharmaceutical Company and the University of Oxford in the United Kingdom, the new crown vaccine developed by Janssen Pharmaceutical Company under Johnson & Johnson in the United States, and the new crown vaccine developed by Moderna in the United States.

WHO officials said that the inclusion of China's Sinopharm vaccine in the WHO emergency use list will help countries seeking to protect health workers and high-risk groups accelerate access to the new crown vaccine.

Two: China's Sinopharm new crown vaccine China's Sinopharm new crown vaccine has obtained emergency use certification from the WHO, which means that the Chinese Sinopharm new crown vaccine has a certain safety and effectiveness, and the WHO recommends that the Chinese Sinopharm new crown vaccine be used for people aged 18 years and above, with two injections, with an interval of 3 to 4 weeks, and the effective rate of the Chinese Sinopharm new crown vaccine for symptomatic patients and hospitalized patients is assessed to be 79%, The evaluation data also showed that China's Sinopharm vaccine also had a protective effect on the elderly. The Sinopharm vaccine is easy to store and identify, and can be applied to areas with scarce environmental conditions, while the Sinopharm vaccine carries its own vaccine bottle monitor, and the small label on the vaccine bottle will change color due to the heat of the vaccine, which is easy to judge whether the vaccine is safe to use.

Three: The significance of vaccination The new crown virus is a new type of virus with high infectivity for human beings, and there are basically no antibodies in the human body that can deal with the new crown virus, and there is no effective means of new crown pneumonia in the world, so the new crown virus is easy to spread wildly among the population. When the vaccination rate of the whole population reaches 70-80%, it can build a herd immunity barrier and effectively prevent the occurrence of mass infection, which is why many countries and regions around the world are strongly encouraging people to complete the new crown vaccination.

Relevant research data show that the new crown vaccine still has a certain effect on the mutated new crown virus, but if the new crown virus epidemic continues to be effectively controlled, as the number of infected people continues to increase, the mutation degree of the new crown virus will be enhanced, and the neutralizing effect of the new crown vaccine will be reduced or even the vaccine will be ineffective.

It means that the safety and epidemic prevention capabilities of China's vaccines have been recognized by countries around the world, which also shows that China is at the world's leading level in vaccine manufacturing and output.

It shows that the vaccine we went home is still relatively safe, and the number of occurrences is relatively small, so it has been recognized by the WHO.

This means that China's new crown vaccine has received international support, and it also shows that China has made great breakthroughs and development in this regard, and it has also been recognized by many countries, improving China's international status.

This shows that the vaccines produced and developed in China have been recognized, with good reliability and safety, and are likely to be used on a large scale in the future.

There are now six vaccines in the world that are in phase III clinical trials, and three of them are indeed from China. This is related to the timing of the discovery of the new coronavirus in China, the attitude of attaching importance to the epidemic, and the level of vaccine research and development at the forefront of the world.

China is the first country in the world to detect the new coronavirus, so China has an earlier and deeper understanding of vaccine research and development. As early as the end of last year, the new crown epidemic was already beginning to take shape. At that time, we knew very little about this unknown disease, and we did not know about the contagiousness and complications, but the Chinese Center for Disease Control and Prevention responded quickly on December 31, dispatched a rapid emergency response team, and obtained first-hand information about the new coronavirus through methods such as whole genome sequencing of pathogen samples.

In the following period, with the deepening of scientific research and the gradual spread of the epidemic, we realized that this is an extraordinary infectious disease, which not only has a long incubation period, but also is highly contagious, and if not timed, it will soon be life-threatening.

China's attitude towards the epidemic is the fundamental reason for the rapid progress of vaccines. Before the epidemic gradually appeared in January, people had been living a seemingly forever safe and stable life, immersed in the joy of the New Year, and no one would have imagined that an epidemic that spread all over the world, with such a huge intensity and far-reaching impact, would quietly descend on the world. Fortunately, my country reacted in a timely manner and immediately took unprecedented strict measures to strictly guard against the epidemic.

This is something that has never had a precedent for decision-makers to suddenly take such a strong approach when the virus is not fully understood and the epidemic situation is not yet fully understood. However, the lives and health of the people came first, and we finally made a correct judgment and began a hard struggle that lasted for several months. While gathering the strength of the whole country to rush to Hubei, vaccine research and development is in full swing.

At this time, the rest of the world is still peaceful, completely unaware of the threat of the coronavirus.

In addition, China's vaccine research and development level is also very advanced. At the first time of the outbreak of the epidemic, five major research directions were determined, and multiple domestic teams carried out vaccine research and development at the same time on their respective technical routes, and had various priority supports. Therefore, up to now, China's vaccine research and development has progressed rapidly and has been generally smooth.

Thanks to the hard work of epidemic prevention personnel and scientific researchers.

Yes, but it is not difficult to understand that China is one of the world's leading countries in terms of response and handling experience with the new coronavirus, and it is not difficult to understand that the largest number of vaccines in phase 3 trials have entered.

It can be seen that the efforts of China's scientific researchers and the progress of vaccine development are very rapid. Since the emergence of infected people in our country, we have started to develop vaccines.

That's right, that's the case, my country has always attached great importance to the R&D investment of the new crown vaccine, constantly overcoming R&D difficulties, and working hard step by step to achieve today's results.

With the development and use of the new coronavirus vaccine, the global epidemic prevention and control capacity has been greatly improved under the role of vaccines. Recently, the WHO has called for prioritizing the vaccination of vulnerable populations, and such an appeal has sparked extensive discussions among countless netizens and friends. Many of these netizens have asked us why we should vaccinate vulnerable people first?

What do I need to pay attention to when getting vaccinated?

In the face of various questions raised by the majority of netizens and friends, and in order to better answer the doubts of the majority of netizens and friends. First of all, we need to fully understand the basic situation of the new coronavirus vaccine. The 2019-ncov vaccine is a vaccine against the new coronavirus.

On April 13, 2020, the same day that China's COVID-19 vaccine entered Phase II clinical trials, a panel of more than 120 scientists, doctors, funders and manufacturers from around the world issued a public declaration pledging to work together to accelerate the development of COVID-19 vaccines under the coordination of the World Health Organization. Vaccination against the novel coronavirus allows our body to produce antibodies to this specific virus, so that we can protect ourselves from this virus. In order to achieve herd immunity for human beings, we must prioritize vaccinating vulnerable populations, because this part of the population has a relatively high infection rate and poor resistance, and it is easy to be fatal once infected with the virus.

Here are some of my thoughts on WHO's appeal. <>

Now, with the continuous advancement of the research and development of new coronavirus vaccines in each country, many countries have a lot of new coronavirus vaccines, but due to the large number of people, there is still a phenomenon that the supply exceeds the demand. In order to better ensure the safety of the relevant population, it is very good to vaccinate the vulnerable population first, which can ensure their health and reduce their case fatality rate. <>

Second, better achieve herd immunity.

Scientists have calculated that if we want to achieve herd immunity, then the vast majority of our entire population needs to be vaccinated to obtain antibodies to the virus. At this time, it is very necessary to vaccinate vulnerable groups, because this group of people is relatively susceptible to the virus, so the World Health Organization's call this time is very correct. <>
