The WHO says it does not recommend booster shots at this time, what are the reasons for not recommen

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 World Health Organization says there are a number of reasons why booster shots are not currently recommended. On the one hand, the focus on the safety of the booster vaccine, and on the other hand, the focus on the degree of vaccine promotion, these two major aspects are the main reasons why booster shots are not recommended at present.

In terms of vaccine safety, the booster shot of the new crown vaccine is still uncertain about the benefits and safety it brings to people, and the booster shot is still in the clinical trial stage, and it will take time to prove whether the booster has greater immunity against the new coronavirus. In addition, at present, we have been vaccinated against the new crown virus, for the general new crown virus, it will definitely have protective effect, and the new crown virus is constantly mutating, it is likely that the virus after the mutation of the new crown vaccine people, the virus can not have a protective effect against the virus produced by the new mutation, so if you continue to get a booster shot, it will only waste the vaccine, and the new mutated virus will be more harmful to the human body, and the development speed of the vaccine is not as fast as the virus mutation, so for the new crown virus, We still have to focus on prevention, and don't think that we have been vaccinated against the new crown and feel that we have protection against the new coronavirus, thereby weakening the protection against the virus, which may allow new mutant viruses to take advantage of the opportunity.

Another reason is that if people all over the world want to continue to get booster shots, the cost of vaccine production is still affordable for developed countries or developing countries, but for countries with relatively backward development, the production of booster shots of new crown vaccines cannot be achieved at all, and people in some countries still have not received the first shot of the new crown vaccine, because the country's funds are simply difficult to support all the citizens to get the new crown vaccine, so from the current situation, the popularization of the new crown vaccine is an important development directionOnly by vaccinating the people of those countries that are lagging behind in development can the new crown virus not continue to endanger human health.

The WHO held a regular press conference on the new crown pneumonia, and the WHO chief scientist said that the WHO recommendation for the new crown booster shot is not to recommend the booster shot at this time, because the available scientific data does not have conclusive evidence that requires a booster shot. But the scientist also said that booster shots may be given to some specific groups of people in the future, such as some elderly people. In addition, the new coronavirus variant may eventually cause us to need a booster shot.

But now is not the time to recommend a booster shot.

1. Booster shots.

Although the WHO says so, according to the available data, the existing vaccines cannot guarantee that everyone will not be infected with the new coronavirus, and there are many mutant strains of the new coronavirus on the market, and their immune escape ability has been full. Therefore, for the sake of everyone's life, health and safety, it is best to get two shots of vaccine first. As for the booster shot, it is a vaccine shot that can double the defensive effect of the cash vaccine.

So whether to get a booster shot or not depends on the country's arrangement.

Second, the World Health Organization has taken into account that some countries have not yet completed the first dose of vaccine.

Some time ago, WHO's Tedros Adhanom Ghebreyesus once named that the global injection of new crown vaccines is showing an uneven state, rich countries have arranged for people to be vaccinated, and poor countries have not yet finished getting 1% of the people. In this case, it is better to let the poorer countries finish the first and second doses of the new crown vaccine first. Build an immune barrier around the world first, and then consider how to eliminate the new crown cases.

3. The effect of booster shots.

Some time ago, Zhong Nanshan reminded everyone that a booster shot can increase the efficiency of the current vaccine several times, so it is estimated that another booster shot will be given in the future. I think it's a good thing to be able to get a booster shot in the current situation, because the new crown has always been mutating, so how to stop it? Only by relying on the majority of the population to establish an immune barrier and slow down the mutation of the new crown can there be a chance to clear the cases.

The World Health Organization says it does not recommend booster shots at this time. First of all, because the mutation of the virus is very fast, and if you get a booster shot at will, it may not be beneficial for the virus later.

Because the WHO says that there is no complete need for this now, the existing vaccines are particularly good and can also play a protective role.

Although the effect of this booster shot is great, it is also very harmful to the body, and there are some patients with chronic diseases who cannot take this booster shot.

Because they feel that these shots should be given to other areas that do not have vaccines, so that they can ensure that some people are treated fairly.

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.

Because the outbreak of the epidemic in the past two years has also brought great disasters to people, we rarely go out in normal times, because the current epidemic is also relatively serious, and the country has also researched a vaccine, which has also brought people a great sense of security, so the protection against the epidemic is also something that every citizen must pay attention to and pay attention to.

The World Health Organization has called on countries to pause COVID booster shots so that poor countries can catch up as soon as possible in terms of vaccination rates.

World Health Director General Tedros Adhanom Ghebreyesus said at a news conference on Wednesday that the third dose of the vaccine should be suspended until at least the end of September. This will help WHO achieve the target of a minimum vaccination rate of 10% per economy by that date, thereby protecting health care workers and vulnerable populations.

First, the booster shot of the vaccine should also be given to those who need it first.

For the booster shot of this vaccine, I think it has just been developed, and it must not be so common, and I think it is also appropriate to give it to those who need it first.

Second, at the same time, people with strong immunity should also pay attention to protection.

For people with strong immunity, we must also be careful to protect, after all, this epidemic will mutate at any time, and it is also very scary, so it is very necessary for us to wear masks when we don't go out at home.

3. I hope that this epidemic will pass sooner.

For each of us, we also very much hope that the epidemic can pass sooner, because the epidemic has also affected our lives.

During this epidemic period, each of us must pay attention to protection, it is best not to run to a crowded place, because it may be easier to be infected, usually we must protect ourselves, that is, to protect our families, if we run around, we may also implicate our own family members when we go home, so we must pay attention to when we go out, do a good job of protective measures, and we must pay attention to the period when the epidemic has not passed.

I'm very supportive of this, because vulnerable populations are already vulnerable audiences, and we need to protect them.

I'm very supportive of it, because it's protecting everyone, and it's fair to some vulnerable people.

This is also done to protect vulnerable populations from infection, and can also effectively prevent epidemics.

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. <>
