Lu Xiaoyun waved his hand: "Uncle Yang, you misunderstood, I don't mean to make the soldiers seriously ill." To put it bluntly, the reason why people get smallpox is because they have no immunity, and as long as we let the soldiers develop immunity to smallpox, they will not be infected by smallpox in the future. ”

Then, Lu Xiaoyun explained the vaccination to Yang Hong in the most simple and understandable words.

Yang Hong seems to understand whether he understands or not, although he believes in Lu Xiaoyun, others in the army may not believe it.

Once they become suspicious and are instigated by others, they are afraid that there will be chaos in the army.

After all, the King of Chu, Qi Yunxuan and Song Rongsheng still planted someone in the army, and they were not completely cleaned up.

"Yunyun, why don't I let the military doctors listen to it?" Yang Hong pondered for a moment, and said to Lu Xiaoyun in a consultative tone, "To make you laugh, Fengyangguan didn't completely clean up those people, so ......"

"Uncle Yang, I understand, you go and call someone." Lu Xiaoyun smiled lightly.

"You're always so attentive and considerate, taking care of other people's thoughts, what a good girl." Yang Hong said sincerely, "I hope Xiao Jiu can be like you in the future." ”

It would be good if his daughter was so well-behaved, Yang Hong was full of hope, if he grew up in a deserted village and was exposed to it since he was a child, he would definitely be like Yunyun is a caring little padded jacket.

Yang Hong suppressed those thoughts and sent someone to invite the military doctor.

The medics, all of whom had come from the doctor's tent, had checked the condition of the soldiers, and it was clear that they were all showing signs of fever.

Their helpless smallpox seems to be simpler than Feng Han in Lu Xiaoyun's hands, and they have a little more respect for Lu Xiaoyun, people can't be good-looking!

"General, Miss Lu, what are the orders for us to come here?"

"Let Yunyun tell you, I don't know medicine, Yunyun told me, I'm in the clouds."

The military doctors looked at Lu Xiaoyun with hopeful eyes.

Lu Xiaoyun cleared his throat and repeated the principle of vaccination again.

"Miss Lu, does it mean that people can suffer from smallpox, control the severity of their symptoms, and let people carry it themselves?" The medics were quick to respond.

Lu Xiaoyun nodded: "Well, people who have had smallpox and are immortal will basically not be infected with smallpox again." So I wondered, if we all had smallpox once, wouldn't we never have to worry about it again? ”

"But how do we manage the sick people?"

"I have my own way of doing this, but I need your cooperation."

"Miss Lu, but it doesn't matter, we will fully cooperate with Miss Lu. It's just that Miss Lu, can you carefully talk about how to do this vaccination and vaccine? ”

"I have to prepare, I think the whole army will be screened once anyway to see if there are any other smallpox patients, and then I will be vaccinated by the way."

"But there are nearly 200,000 troops in Fengyang Pass, and I'm afraid it's not easy to catch up."

"It's okay, I have time." Lu Xiaoyun smiled, "You guys are just waiting for my news." ”

"I'm relieved to have Miss Lu's words, and we'll wait for Miss Lu's instructions."

After the military doctor stepped down, Yang Hong asked Lu Xiaoyun again, "When will the vaccination start?" ”

Lu Xiaoyun's vaccine is definitely not enough for the soldiers of Fengyang Pass.

And the current scientific and technological conditions are not enough to make a better vaccine, it is best to plant cowpox, followed by the dry seedling method and the water seedling method.

The dry seedling method is to grind the pox scab shed by the convalescent smallpox patient into powder, and blow it to the nostrils of the inoculator with a tube, and the water seedling method is to moisten the pox scab ground into powder with water, and then wrap it with cotton balls and stuff it into the nasal cavity.

Cowpox is relatively safe.

But there is some trouble in extracting the cowpox virus, Lu Xiaoyun wanted to solve the smallpox in Fengyang Pass as soon as possible, so he decided to use the dry seedling method, after all, there are so many people, if cotton is used, it is not a small burden, the imperial court is guarding against Fengyang Pass, and the materials are afraid that they can be carded!

Lu Xiaoyun told Yang Hong his thoughts.

Yang Hong was stunned for a moment, but thinking that Lu Xiaoyun was in charge, there was nothing to worry about.

There are many soldiers in Fengyangguan, so they isolate those who may be infected, and then come to be vaccinated in batches, without delaying anything.

"After vaccination, smallpox symptoms may occur, but with the physique of Fengyangguan soldiers, there should be no problem. But I still have to tell Yang Erbo, it's not completely controllable, and it may lose your life because of it. ”

"It's not that I'm cold-blooded, I'd rather die than risk an army of 200,000. As a general, the first thing is to protect the family and defend the country, and then this is yourself. Since I am stationed in Fengyang Pass, I must be responsible for Fengyang Pass and the people of Northwest China. You don't have to say these words to anyone else. ”

Lu Xiaoyun looked at Yang Hong, Yang Hong's expression was firm, and he didn't say anything.

All in all, she will stay in Fengyang Pass for a while longer, see what symptoms will appear, and then tell the military doctor how to deal with it, the military doctor is experienced and should be able to deal with it.

In the next few days, Lu Xiaoyun got busy.

However, Lu Xiaoyun did not fall with cowpox, so he asked people to find a few cows, let the cows be infected with smallpox, and then try to extract cowpox.

The military doctors were dumbfounded when they knew Lu Xiaoyun's method of inoculating pox vaccines.

In the past, there were people who tried to make people wear smallpox clothes, but in the end, many of these people died, and after that, no one dared to touch the smallpox patients' things.

The first pox sprouts came out quickly.

The soldiers were all resistant, and Yang Hong ignored everyone's opposition and was vaccinated as soon as possible.

Seeing this, Ye Mao and the others felt that there was no reason to fall, and they were inoculated with the vaccinia together with the military doctors.

During this time, they all had symptoms, but unlike the previous soldiers, they were relatively mild, and after a few days, they were cured.

There was a military doctor who was more bold, and after he recovered, he took the initiative to contact smallpox patients, and even took the initiative to collect sores from smallpox patients and stuff them into his nostrils.

This result greatly deepened the confidence of the soldiers in the vaccinia.

Many people resisted from the beginning and began to look forward to getting vaccinated earlier.

After all, soldiers in the army who have not yet been vaccinated have also begun to develop smallpox one after another.

Fortunately, Lu Xiaoyun is in charge, and Lu Xiaoyun does not hide private military doctors, and there is no chaos in Fengyangguan.

Outside the border pass, the commander of the people of the Western Regions has been waiting for the so-called opportunity, but he is looking forward to it left and right, and what he is looking forward to is that the Fengyang Pass soldiers who go to the city wall every day are not sick at all, but have a surprising spirit.

"Damn the Great Wei people, they are really insidious and cunning, the Fengyang Pass army has not been infected with any smallpox, fortunately we did not act rashly, otherwise we would have fallen into a trap." After waiting for more than half a month, the boss of the Western Regions finally recognized the reality that there was no accident in Fengyangguan!

At the same time, he gritted his teeth with hatred for the messenger, "If I have a chance to attack Great Wei one day, I will definitely kill that person as soon as possible!" ”
