How do people develop vaccines? What do you think?

The principle of vaccine development is to make immune preparations for the prevention of infectious diseases by artificially attenuating, inactivating and transgenic methods of pathogenic microorganisms, such as bacteria, viruses and their metabolites. My view is that with the development of random medical technology, the development of vaccines will get better and better to protect human health.

The principle is to develop according to the atomic structure and substructure of the vaccine, find drugs that can inhibit these atoms, and then develop the vaccine. My opinion is that the effect of these vaccines is very good, and the effect of each vaccine is different, and each vaccine is very helpful to our body and can improve our body's resistance.

According to the source of the influenza virus, and then mixed with related drugs, the effect of epidemic prevention can be achieved, and then the vaccine can be developed, which is very good, and the safety factor is particularly high.

The principle of people developing vaccines is that a small amount of viruses can make the body's immune system produce antibodies, and vaccines are actually fighting viruses with viruses, which can make the human body adapt to the virus and have a stronger ability to adapt in life.

In the process of vaccine research and development, China's scientific and technological workers have changed the traditional tandem model toParallelMode.

Vaccines refer to biological products made from various pathogenic microorganisms for vaccination. Among them, vaccines made with bacteria or spirochetes are also called vaccines. There are two types of vaccines: live and dead. Commonly used live vaccines are BCG and polio vaccines.

Measles vaccine, plague vaccine, etc. Commonly used dead vaccines include pertussis vaccine, typhoid vaccine, cerebral flu vaccine, cholera vaccine, etc.

The timing of the production of different vaccines varies:

The production time varies from vaccine to vaccine, and some vaccines can take up to 22 months to produce a batch. Vaccine development is a long and complex process that can be costly. Vaccination is the most economical and effective public health effort to prevent and control infectious diseases.

Interventions are also an effective means for families to reduce the incidence of illness and reduce medical costs.

It is estimated that immunization averts between 2 million and 3 million cases of diphtheria and tetanus each year.

Pertussis and measles lead to the death of the number of wheels. Global vaccination coverage (the proportion of children globally who receive recommended vaccines) has remained stable over the past few years.

The first vaccine developed by humans was the vaccinia vaccine, also known as vaccinia vaccinia. It was discovered in 1796 by the English physician Edward Jenner. Jenner observed that farmers often suffered from cowpox, a mild bovine disease, but they were less susceptible to severe smallpox.

Based on this observation, he collected the rash of a cowpox patient and injected it into a healthy boy. The boy experienced a brief illness, but quickly**. A few months later, Zhan asked Kina to inject the boy with the smallpox virus, but he was not infected with smallpox.

This experiment proved that vaccinia can provide immune protection, making it the first successful vaccine.

Whether the vaccine is good or not, how long is the immunization rate and timeliness of the vaccine against the corresponding virus, whether it is effective when the corresponding virus mutates, whether the vaccine will affect the body after vaccination and the high probability of the impact on the essence of the human body in the later stage. Whether it is good or not is not what everyone thinks now, but the results of scientific data a few years later.

Susceptible people are usually people who lack specific immunity to an infectious disease and are susceptible to infection. The population is generally susceptible to the new coronavirus, and people of all ages have no immunity to the new coronavirus. After being infected with the new crown virus or receiving the new crown vaccine, the human body will produce antibodies, and it will develop a certain immunity to the new coronavirus.

Big, two needles of more than 1,000 yuan, although you don't have to pay for it personally, but it is paid by the state, 100 million people is 1 trillion, how can this money be divided, you can look at the first needle gifts that have appeared in various places, and there are even cross-regional car pick-up and return to red envelopes, which is really intriguing.

Vaccines are effective against viruses, but they are not particularly effective. So I haven't been vaccinated yet. After all, the role of vaccines is nothing more than to stimulate antibodies in the human body. Without vaccination, the human immune system can also produce antibodies.

I think the role of the vaccine is very large, the vaccine can form a barrier against the virus in the body system, and the vaccine is designed according to the characteristics of the internal molecules of the virus, and it has good resistance and destruction to the virus, so I think the role of the vaccine is very great.

The role of the vaccine cannot be as simple as a size. Vaccination has different effects on society, individuals, and the degree of damage caused by the epidemic, and the size of the simple vaccine is neither rigorous nor serious!

I don't know if it's big or not, it's definitely not too good if you don't get vaccinated, which is equivalent to a 1 in 10,000 chance that you don't get vaccinated and have a 99% defense effect against the virus.

According to the history of infectious diseases, vaccines are very effective, such as smallpox, measles, and other serious infectious diseases are basically invisible now, which means that they are effective.

I think the vaccine has a great effect, although it cannot protect against the virus 100%, but after vaccination, it can strengthen the antibodies, and it will be more effective in fighting the virus.

The role of vaccines is very large, and there are many infectious diseases in history, which have been effectively controlled through vaccines. Vaccines allow the body to develop antibodies to the virus.

It is called a vaccine if it can effectively prevent infection. It is not effective in preventing infection, there is no obvious ***, but it can inhibit the exacerbation of the disease called drugs.

Vaccines have strong immunity to the virus in response. Of course, one vaccine can only be effective against this one virus.

This needs to be done in scientific research, data comparison, not who thinks, now just solve the problem?

Prevention is important, but strengthening physical exercise and improving the body's immunity is the key.

I don't know anything else, but it's true that smallpox was wiped out by vaccines.

If you really hit it, you won't be infected, the key is that the role of ideology is huge.

Developing a virus buster is the last word, and even if you are infected, you can be cured immediately.

Universal immunization may be more reliable, but the key is that it has little impact on the economy.

The effect is not considered to be large, because it has already been played.

I always caught a cold after I was hit, and my resistance decreased.

If you like it, you can play every day, every month.

Large-sample randomized, double-blind controlled trials are required.

Oral vaccines are being rolled out as soon as possible.

Globally, the new coronavirus is raging, posing a great threat to human beings. However, when we look back at the development process of vaccines, we can find that the process of vaccine development reflects the scientific spirit of scientists' excellence, continuous exploration, and continuous innovation.

First, the attitude of excellence.

In the process of vaccine development, scientists have conducted rigorous research on all aspects of the vaccine. They are constantly analyzing the results of trials to improve the effectiveness and safety of vaccines. In response to different epidemic mutations, scientists have also responded in a short period of time, conducted targeted research, and continuously improved vaccines.

This scientific attitude of excellence provides a solid foundation for the development and production of vaccines.

Second, the spirit of continuous exploration and innovation.

In the process of vaccine development, scientists have to face unknown challenges and continue to experiment with vaccines to find optimal solutions. Scientists are constantly trying to discover new vaccine principles and improve the way vaccines are produced. Continuous innovative research has promoted the development and progress of vaccines.

Guess the good deeds. 3. Practice the pragmatic spirit of true knowledge.

Vaccine development requires continuous experimental validation, and scientists need to spend a lot of time and energy to verify the efficacy and safety of vaccines. The success of a vaccine depends on the results of numerous experiments and studies. Therefore, in the process of vaccine development, scientists must have a high degree of practicality, conduct a large number of experiments, and support the research process.

Conclusion In the period when the new crown epidemic is raging, the research and development of vaccines has become a ray of hope for the entire human struggle. Behind the vaccine research and development is the strong scientific spirit of scientists, which permeates every link of vaccine research and development. In the face of human disasters, scientists have contributed to the cause of epidemic prevention and control with unremitting efforts and tenacity.

I believe that as long as we move forward under the guidance of science, we can defeat the epidemic and bring mankind back to normal life!

This year's new crown virus has set off a bloody storm all over the world, first in our country, and then spread to the whole world, fortunately, our country has brought the epidemic under control, but the situation abroad is not optimistic now. When we were successful in the pandemic, many countries came to us to ask for lessons and when asked how much money they spent on this pandemic, all countries were silent when they saw this data, and I don't think there is any country in the world that has the courage to do this kind of thing like us. For the new crown virus is completely free, this alone is very few countries can do, and our country has a large population, so it has invested a lot of financial resources and materials, according to incomplete statistics, our country has invested 116.9 billion yuan in this epidemic.

Because our testing for the new crown virus is free, as long as you buy China's medical insurance, you can enjoy it for free**, I believe everyone knows that we are a large population, so far we have a total of more than 80,000 confirmed cases, and the cost of testing alone will cost millions of yuan a day. In addition, in addition to investing in our own countries, we also support countries with serious epidemics abroad, and also donate a lot of materials to them, in fact, the input cost of the epidemic is a drop in the bucket compared to the loss, because enterprises cannot resume work during the epidemic, resulting in many enterprises have closed down, and the losses in all aspects are the most serious. In addition to the cost of investment in our country, we have also extended a helping hand to those countries where the epidemic is severe, and donated a lot of materials to them.

For example, the United States is still hiding the epidemic until now, and there are still many people on the street who do not wear masks when they go out, because their country's epidemic prevention and control propaganda is not in place, and a large number of people have not been dispatched to control it, so the epidemic will appear uncontrollable. After this epidemic, I believe you can also see the attitude of each country towards the people, a capitalist country like the United States, there is no human touch to talk about, in addition to asking you to pay the expensive ** cost, even the testing reagents are still very scarce, many ordinary people are not even qualified to test, China can be said to have invested in the cost of this epidemic, I believe that no country can do as perfect as us.

Scientists point out that the health of modern people is closely related to vaccines, and it is difficult to imagine what human society would be like today without vaccines. In the past, vaccines were only used to prevent disease. However, with the development of medical science and technology today, the concept of obesity vaccine was born.

The principle of this special vaccine is that the vaccine is in the human body to produce an immune response to peptide hormones, which are amino acids secreted by stomach cells.

For the invention of the vaccine, the following was used

a.Azimuth reversal.

b.Because of filial piety, the fruit is reversed.

c.Attribute surplus reversal.

d.Psychological reversal.

Correct answer: B
