The road from Africa to Europe

Chapter 130 Is it unexpected?

The atmosphere at the moment is very harmonious, and they have not gathered together for a while.

They all have their own homework to do, except for Zhang Shanshan, all three of them have done internships.

If they want to graduate, they have to write a thesis, check a lot of information, and too many things occupy their time.

Even if they are one step ahead on the way forward, it does not mean that the people behind will not catch up, and they must work hard.

As a result, the four people in their dormitory have very few opportunities to have dinner together, and there will be even fewer opportunities to gather in the future.

All four of them think of this, so they will cherish the present opportunity very much. They cherish the friendship very much, and they may meet friends who get along well after they leave the society.

But it is more likely that you will never meet friends with such a suitable temperament again, and it will only make people's friendship mixed with more interest disputes in society.

Once interests are involved, it would be good to be the most ordinary friend in the end. Fortunately, it is enough to make friends who will become lifelong friends when you are in college.

After the four of them ate at a steady pace, they ran to the viewing platform to see the night view. Few people in the entire city of Z were taller than this building. Sitting on the viewing platform and looking down, the whole city was full of Bright lights and lots of traffic.

Zhang Shanshan sat down and looked at the night scene and didn't care much. She is immune to this kind of scene after seeing a lot of night scenes, but the other three are somewhat interested.

Although they have also seen the night view of the whole city, it was from photos, but this moment is different. Standing in the sky, there is an indescribable excitement.

After waiting for a while, she finally asked, "Xiao Xiao, I want to ask you something. If you have a baby, do you want to vaccinate the newborn?"

She wants to be a good mother and is studying how to be a good mother. It is said that Dongdong will learn how to be a good parent together.

Several girls in the dormitory looked at Zhang Shanshan with some interest, and she was the only one in the dormitory determined to be a good mother.

For this goal, Zhang Shanshan read a lot of professional knowledge, and also specially recorded some precautions for infants and young children.

But today, I just want to ask about vaccinations. She has seen too much, and her thoughts are a little confused.

After hearing this, Ling Xiao was a little surprised. It is normal for newborns to be vaccinated from birth.

So why did Zhang Shanshan ask such a question?There must be some trend of thought that affected her thoughts.

"You said, do you want to vaccinate the child?" Ling Xiao asked rhetorically.

She looked at the other roommates as she spoke, and Zhang Shanshan looked at them.

"I remember that if I don't get vaccinated, I'm afraid I won't be allowed to go to school." Xiyan said.

I remember that when I signed up for elementary school, I always brought a special vaccination record book, and I still typed it when I went to school.

Their generation has received a lot of vaccines, and the first two vaccines should be given 24 hours after birth.

Qian Rui said: "To get vaccinated, for example, after people are bitten by cats and dogs, they must get vaccinated immediately."

"I know this. If you are bitten by a cat or dog, wash the wound first. You can wash it with tap water. After washing, you must expose the wound to the outside, because the rabies virus is anaerobic." Xi Yan said.

Zhang Shanshan nodded and said, "I'm not talking about the rabies vaccine, but the vaccine given at birth. Is it necessary?"

Xi Yan and Qian Rui really wanted to say that of course they had to be vaccinated, otherwise why would the country let everyone get vaccinated for free?

But they didn't say anything in the end, but looked at Ling Xiao, who was studying medicine, hoping that she would answer.

"Need to fight, unless the immune system is deficient and low." Ling Xiao said.

"Also, people with allergies and illnesses cannot be beaten."

"However, it is said on the Internet that in Europe and the United States, many people say that vaccination is not good."

After hearing Zhang Shanshan's words, Ling Xiao knew that the mother-to-be was at a loss.

After hearing this, Qian Rui opened her mouth and still didn't speak. She is the one who hangs out a lot on the Internet in the dormitory.

The news on the Internet is often false, but when making false news, it is often mixed with real things, which is difficult to distinguish.

This has led to a lot of fake news being circulated on the Internet. Over time, the so-called fake news has become true news in some people's minds.

Zhang Shanshan could see that the roommates in the dormitory didn't take it seriously, so she said: "Some people say that after the vaccination, the children will affect their development and become infertile. Some people will die directly after being vaccinated."

As a mother-to-be, she wanted to provide the best environment for her children, and she really wanted to know more, so she came to ask Ling Xiao.

"Affect development? Infertility? Hehe! We have been vaccinated since the founding of the People's Republic of China? I remember it was cowpox to prevent smallpox."

"So, Shanshan, do you think our generation, the previous generation, has affected development? Has it caused infertility?"

In fact, after the founding of the People's Republic of China, the life expectancy of both men and women has been greatly improved, and their stature has also grown a lot.

puff!Xiyan laughed and said, "When the country was founded, the population was about 1.3 million, but now it is [-] billion."

"This is only after the implementation of mandatory family planning, and there is not much growth."

So the so-called result is not a fact at all.

Xiyan's words made Zhang Shanshan suddenly realize.

What affects development, infertility does not exist.

"Of course vaccination has certain risks," Ling Xiao said.

There is no doubt about this. In fact, there are cases of death after being vaccinated.

Zhang Shanshan sat up straight when she heard this, and looked at her roommate seriously.

"The most common vaccines use various methods to attenuate and inactivate the original strains of viruses and bacteria."

"Attenuation? Inactivation?" Everyone was a little confused, "It means reducing the toxicity of the virus and turning it into a dead vaccine, so that the human body suffers less damage."

"For example, the BCG vaccine for newborns is an attenuated vaccine. The vaccine still has a certain activity, but the toxicity of the virus is reduced, and it has a long anti-infection effect, and even does not need to be revaccinated."

"This kind of vaccine also has shortcomings. The active vaccine will make people with low immunity get sick, and the mutation will restore the virus's virulence. However, scientists have been working on making the vaccine unable to restore the virulence over the years."

The other three people looked at each other in blank dismay. It turned out that it was really dangerous, so Ling Xiao said: "Vaccination is not for everyone."

"I just remembered that I also specifically mentioned that there are contraindications to vaccinations. Everyone should pay attention before vaccination."

The three of them thought about it, as if they had just heard about it, and now they were reminded to think about it again.

"Yes, Xiao Xiao just said that the immune system is deficient, low, sick, and allergic."

"Neither of these situations can be fought." Zhang Shanshan said after thinking for a while.

Others are also thinking about it.

At the same time strengthen their own memory.

These precautions are very useful for them.

"When vaccinating, doctors will remind parents of contraindications."

"Know that vaccines are for protecting everyone, not killing people," Ling Xiao said.

"There is also an inactivated vaccine with weak immunity, which may require multiple vaccinations."

"In addition to the two mentioned above, there are toxoid vaccines, subunit vaccines and peptide vaccines, vector vaccines, nucleic acid vaccines, edible vaccines, etc."

Hearing this, the others were a little confused, because they only knew that they had to go to the hospital or the CDC to get vaccinated, and they never thought that there were so many ways to make vaccines.

Ling Xiao said: "Why are there many ways to make vaccines? It is because researchers want to find safer ways to make vaccines to make humans safer."

The three listened carefully. They may be elites in their own industries in the future, but they are novices in medicine.

Ling Xiao glanced at the three people. In fact, in her opinion, vaccination is indeed dangerous.

But the risk of not getting vaccinated is even greater because of the viruses and bacteria that make the vaccine.

They are all highly contagious, and it is easy to get infected if you don't fight them.

After playing, the possibility of being infected is greatly reduced.

This is a way to stay safe.

Zhang Shanshan still looks a little worried.

She thought of a very surprising thing and planned to say it.

Let them grow their knowledge, knowing that there are too many unsolved mysteries.

"Did you know? There are actually virus genes in human genes, which are the traces left after being assimilated."

Hearing this, everyone is ignorant, what?At this moment, they all have the feeling that they have heard it wrong. The virus gene is actually reflected in human beings?

Ling Xiao told them before that, except for the indigenous Africans who do not have the Neanderthal gene, humans who are descendants of Homo sapiens have the Neanderthal gene. After thinking about it, they had to accept this possibility.

After all, DNA cannot deceive people. No matter what means Homo sapiens used in the early years to obtain the genes of Neanderthals, as a younger generation, they can only accept them. Is it possible to get rid of the so-called things?It simply cannot be done.

Maybe even after being eliminated, they will not be the current human beings. As the younger generations, they are powerless and can only accept this fact.

As a result, Xiao Xiao told them now that human genes still carry virus genes, which is really confusing.

In the past, they thought that human DNA and RNA were unique.

Even if it has Nepalese genes, it is still a gift from relatives.

Homo sapiens and Neanderthals are true relatives.

As a result, a new discovery came.

Virus genes in human DNA?

Qian Rui blinked and said, "Is this true?"

"Really, it's more real than pearls, it's just so magical."

"Scientists have not stopped exploring the mysteries of human beings over the years."

"This is a scientist who went to study human DAN, and this discovery was made."

"I even put forward an idea: it was the participation of ancient viruses that created mammals, that is, humans and all mammals. If there were no virus genes added, maybe they would not have evolved into mammals."

Only other people know that there are so many secrets in human genes, and maybe there will be more.

The impact of the virus on people is much more than they imagined, and it is more intimate.

The others are a little dumbfounded at the moment, how should I describe this feeling?

The more you know, the more you realize that you don't know much.

Today is also a science time.

"How is it? Is it unexpected?" Ling Xiao asked.

Accident!Of course it was quite a surprise, the three of them nodded repeatedly.

"Shanshan, do you need to be vaccinated for the virus? I want to give an example that everyone knows."

"That is the smallpox virus that everyone should be most familiar with. Do you know what its fatality rate is?"

The three of Xiyan and the others looked at each other. They knew about this virus, but they didn't know the fatality rate.

But everyone knows one thing: smallpox is very dangerous and highly contagious. Qian Rui knew that the Inca Empire in America was destroyed by smallpox virus.

"The lethality rate of smallpox virus is 30.00%, that is to say, [-] out of [-] people who get sick will die from smallpox virus." Ling Xiao said.

"This is in the absence of a vaccine, only the immune system is allowed to work, 70.00% of people can survive, and even if they are alive, they often have pockmarks on their faces."

When Ling Xiao said this, he paused, looked at the others, and wanted to see if they understood?The others nodded, smallpox is terrible.

"As for the smallpox vaccine, I know that it is vaccinia that prevents smallpox, and smallpox has been eradicated," said Qian Rui.

"Yes, the WHO announced that smallpox was eradicated. It is the only virus that has been eradicated. This generation has not been vaccinated against vaccinia."

"However, it seems that the so-called smallpox virus still exists, and the original strain still exists in some laboratories." Xiyan interrupted suddenly.

"On the surface, there are a few laboratories that still have specimens, but who knows how many are in private." Ling Xiao said in his heart.

This was her own guess, so she didn't say it out loud because there was no evidence.

Zhang Shanshan is a little excited at this moment, why does this harmful virus keep?

"Why are there still specimens left? They should all be wiped out."

All three looked at Ling Xiao, hoping to give an answer.

"If you don't keep it, how to find the most primitive virus if you need to study it?"

The three people's eyes widened, but they still agreed that the smallpox virus should be completely destroyed.

And Ling Xiao said at this time: "The biggest question now is, can you say that what these people say must be wrong?"

Life on earth sometimes needs diversity, and the smallpox virus is also a part of life on earth. Would it be bad to remove it?

"There is no way to know right and wrong. Maybe only after many years will our descendants know whether it is good or bad to keep the smallpox virus." Ling Xiao sighed.

"But future generations cannot give warnings to modern people from the future. Even if modern humans have been warned, do we dare to believe it?" Ling Xiao asked.

"There was a scene in a sci-fi movie. Both the pros and cons sent robots back through time and space to protect or kill the leader of the resistance alliance in childhood. As you, which side would you believe?"

After Ling Xiao's words came out, the three of them suddenly remembered that very famous sci-fi movie, which had been filmed for several episodes in a row, and the pig's feet were even more famous.

"Xiao Xiao, are you talking about the Terminator? The leading actor has gone through a lot of ups and downs, filming one after another." Qian Rui finally spoke.

"When watching a movie, we, as the audience, have God's perspective and know who is the real one? Who is the villain? You can choose your side."

"But when it comes to whether to keep the smallpox virus, even if there are future messengers who arrive, they still give opinions."

"The problem is that we don't know whether the envoy is a positive or a negative, so how should we deal with it?"

When Ling Xiao said this, he shrugged his shoulders, really unable to decide.

when making each choice.

No one can guarantee that the choice is correct.

Human beings can only cross the river by feeling the stones when they make choices again and again.

Maybe success, maybe failure, human beings must bear the consequences of right or wrong choices.

Even sometimes, the choice of the road proved to be correct at the beginning, but it was discovered that it was not correct at all after many years.

Or the road that was thought to be wrong at first turned out to be the right road to walk through.

After hearing Ling Xiao's words, the others also remained silent, not knowing what to do?

They don't know how to make a choice.

Don't know the direction at all.

It was Zhang Shanshan who broke the silence.

"We can't control the smallpox virus."

"It's just that there should be vaccinia vaccines left?"

"Yes, the WHO recommends that each country retain this vaccine."

"Then in case there is another outbreak, at least it can be produced as quickly as possible."

Although Zhang Shanshan felt that she should be vaccinated after hearing Ling Xiao's words, she still asked new questions.

She said: "Well, Xiao Xiao, I see that many people in foreign countries say that vaccination will have side effects, especially the measles vaccine, and they say that there is brain death."

When Ling Xiao heard this, the corner of his mouth twitched. As a person who loves the motherland, he had to admit that the motherland started slowly. When Europe and America had entered industrialization, this place was still a feudal monarchy.

This caused the ancient Kyushu civilization to lag behind other countries step by step for a long period of time.Later, it suffered repeated invasions and almost became a colony.

Today's science started much later, lagging behind European and American countries in many aspects.
