Copying the heavens begins with Tianlong

Chapter 74 Vaccination
Duan Yu, who was taking notes, stopped when he heard this and asked, "Brother Dong, can you cure smallpox?"

Lin Yaodong shook his head.

"It can't be cured! But it can be prevented, so that people all over the world will never get smallpox again!"

When Duan Yu and Duan Zhengchun heard this, they did not doubt the authenticity of Lin Yaodong's words.

In their hearts, Lin Yaodong is a god-like figure. If the other party says it can be prevented, there must be a way.

Immediately he became excited.

Smallpox is a disease that makes people blush and avoid it.

In recent years, there have been many smallpox epidemics in Dali.

Countless people died as a result.

This infectious disease with extremely high fatality rate cannot be treated at all in this era of backward medical care. Once infected, one can only resign oneself to fate.

The methods of dealing with smallpox are similar in all countries. Once discovered, they immediately send troops to blockade, wait for everyone to die, and then burn and bury it!
The low population in ancient times was not only due to food problems and wars, but also to a large extent due to various diseases and plagues.

Throughout the ages, many medical practitioners have been researching prescriptions to treat smallpox, but no one has succeeded.

Now that Lin Yaodong has proposed a method to prevent smallpox, it is a great thing for people all over the world.

Duan Zhengchun couldn't help but breathe quickly.

Eliminating an infectious disease is not only a huge political achievement, but also a great thing that benefits the country and the people.

Among other things, if smallpox could be prevented, the mortality rate of children around the world would be greatly reduced.

His Duan clan can also benefit from this and benefit future generations.

It's equivalent to having an extra gold medal to avoid death.

Duan Zhengchun calmed down, straightened his body, looked solemn, and bowed to Lin Yaodong.

When Lin Yaodong saw this, he didn't even move his body.

Preventing smallpox is such a blessing!
Duan Zhengchun can get it just by paying homage. If you tell me, many emperors will be so envious that their eyes will turn red.

Lin Yaodong could afford the other party's bow.

After paying homage, Duan Zhengchun looked at Lin Yaodong and said excitedly: "Yaodong, please tell me how to prevent smallpox?"

Duan Yu on the side watched his father salute Lin Yaodong and was not surprised.

My Dong brother is such a person, what’s wrong with being worshiped?
He even felt that Duan Zhengchun didn't do a good enough job, and if it were him, he would be in trouble.

Lin Yaodong didn't care about these falsehoods and said bluntly: "The way to prevent smallpox is actually very simple, which is vaccination."

"Vaccination?"

Duan Zhengchun and Duan Yu heard this word for the first time, and they didn't know how powerful it was.

In fact, during the Zhenzong period of the Song Dynasty, there were records of vaccination in the Song Dynasty.

Wang Dan, the prime minister at that time, had several children die of smallpox. He was afraid that he would suffer another misfortune when he had a son in his old age, so he looked around for ways to prevent and treat acne.

Later, eminent monks and miraculous doctors were invited from Mount Emei in Sichuan to inoculate his son against smallpox. He developed fever seven days after the inoculation and scabs formed in twelve days. From then on, he was immune to smallpox.

But what he had was variola.

This method is not easy to use and the risk is extremely high.

Because having variola on your body is like actively contracting smallpox!
The disease is coming like a mountain, with fierce momentum!
Many people immediately developed high fever and died unexpectedly. The survival rate was very low, and there were very few people who could survive it!

Therefore, this method has not been promoted, its reputation is not obvious, and few people know it.

The vaccination Lin Yaodong mentioned was naturally not variola, but the proven cowpox.

Lin Yaodong explained: "The so-called vaccination is a measure to inoculate the human body with cowpox vaccine so that the human body can acquire immunity to smallpox."

"To put it simply, a virus that can cause cowpox rash is used to infect people. Since the virus is very weak in humans, the symptoms of the infected person are very mild, and it will only cause mild herpes and local scars."

"People who have been vaccinated against cowpox will naturally develop resistance to the cowpox virus and will not be infected again for several years."

"Because the antigenic structure of the cowpox virus is similar to that of the human smallpox virus, when a person who has been vaccinated with cowpox encounters the smallpox virus again, the body's immune defense system will "mistakenly think" that the cowpox virus is coming again and will eliminate the smallpox virus, so the person will not You will get smallpox again, which is called cross immunity in medicine."

"This method has a high success rate and is not dangerous."

"Generally healthy people can survive a low-grade fever for a few hours."

"From now on, I will never get smallpox in my life."

Lin Yaodong explained briefly.

Some of the professional terms, such as virus, immunity, immune virus, etc., were not understood by Duan Zhengchun and Duan Yu.

But the general meaning is still clear.

The key is that as long as you know which cowpox to plant, you can prevent smallpox.

Duan Zhengchun immediately decided and summoned people from Tai Hospital to verify.

Imperial doctors are considered professionals. After Lin Yaodong's explanation and careful consideration, they feel that it is very feasible and poses a great challenge to their profession.

Also extremely happy. Although vaccination was proposed by "His Majesty", as a participant, once it is successful, it will be a blessing to all people.

When the time comes, they will also be able to shine brightly and be famous in history.

Who wouldn't be excited when this kind of overwhelming wealth that can open a separate page in the family tree is suddenly hit on the head?
As for the selection of vaccinations, it is also simple.

Just find some felons in the sky jail.

If you can resist it, your sentence will be reduced. If you can't resist it, it will be treated as an early execution.

This matter was against the harmony of heaven and Duan Zhengchun did not say anything clearly.

The people below need to understand it themselves.

If something goes wrong, the people below will have to take the blame.

Compared with the several months it takes to see results with food, vaccination with pox is much faster.

It only takes a few days to see results.

After the cowpox was inoculated, when the vaccinated person recovered, they were sent to a different village where smallpox existed. If they stayed together for a period of time and did not contract smallpox, it was a success.

During this period, Duan Zhengchun and Lin Yaodong were not idle, preparing for the next war.

The main force is not the tens of thousands of people in Dali, but the bull mantis in Lin Yaodong's real encyclopedia.

During his travels, Lin Yaodong included large swaths of African grasslands, expanding his territory to 28 pages.

After secondary breeding, there are now more than 5,000 bull mantises, all of them adults, all fat and strong.

You can easily kill someone.

Lin Yaodong tamed the leading bull. As long as he rode the leading bull, the other bull mantises would follow and charge into battle.

Once five thousand bull mantises start running, they will be like a torrent of steel, invincible.

After raising them for so long, in addition to eating meat, Lin Yaodong also wanted to test their power on the battlefield.

The Song and Liao battlefields are the best touchstone.

If you want to establish your authority, you have to achieve results.

Peace is never sought, but fought.

……

a few days later.

Dali Palace.

Doctor Qi reported the results of cowpox to Duan Zhengchun with excitement on his face.

"Your Majesty, cowpox is here!"

Duan Zhengchun trusted Lin Yaodong very much and knew that the matter was very certain, but he couldn't help but feel elated when he heard the report from Doctor Qi.

Just in case, I asked for details.

After learning that cowpox was truly effective, Duan Zhengchun immediately officially promoted vaccination in Dali.

Because of the scarcity of farm cattle and inconvenient transportation, promotion will be slow.

But overall, it’s still a great blessing.

In order to build momentum and set an example, Duan Zhengchun took the lead and asked the Duan family to vaccinate cowpox in public to calm the people.

Duan Yu, Wang Yuyan, A'Zhu, A'Zi, and Mu Wanqing all participated.

This approach has many advantages.

Vaccination with cowpox can prevent smallpox and give you an extra layer of gold.

It also facilitates promotion work.

When the people saw that the emperor's family was taking the lead in vaccination, there were countless followers.

In this era, no one, from the emperor to the poor, was afraid of contracting smallpox.

Now that there are ways to prevent it, enthusiasm is naturally high and implementation is going smoothly.

Duan Zhengchun's prestige has been greatly improved through the propaganda of thoughtful people.

The people all sing praises for their virtues.

This move alone won a wave of popular support, and with the help of those promoted cronies, Duan Zhengchun was able to completely control the military and political power of Dali.

After receiving the news, other countries sent envoys to Dali to seek a method of vaccination.

Even the Song Dynasty and Liao Dynasty, which were about to go to war, sent envoys.

This shows how much fear smallpox brought to people in this era!
Duan Zhengchun followed Lin Yaodong's suggestion and openly announced the methods and theories of vaccinia cultivation.

This is a great contribution to the contemporary era, will be beneficial to the future, and will benefit the world. It is enough to make Duan Zhengchun famous.
