Zuo Menggeng told her that after being vaccinated with cowpox, her body would have the same reaction as if she was infected with smallpox.
She wasn't sure if it was contagious, so she had to self-isolate just in case.
There is only one student named Shen Xiaoyu who is with her and is responsible for taking care of her food, clothing and daily life.
Although Shen Xiaoyu is a little girl, she is very brave. Following her instructions, no protection was taken.
The purpose was to test whether people vaccinated with cowpox could transmit smallpox to others.
Lu An passed out that day.
The whole body feels hot and dry, like coals of fire.
This frightened Shen Xiaoyu so much that she quickly followed the instructions and used ice cubes, wet towels, alcohol and other items to help her cool down.
After a full day of busy work, Lu An's high fever finally subsided a little.
By the next day, Lu An's condition was slightly better. Although he hadn't woken up yet, there was no rash on his face.
Shen Xiaoyu was on the sidelines, recording all the changes in detail.
On the third day, Lu An woke up.
Although there is still some residual heat, his consciousness is relatively clear. He is just weak and unable to move. However, he can feel hungry and eat a full pound of meat.
On the fourth day, Lu An could get out of bed.
The fever symptoms have completely disappeared, and there is still some dizziness, but it does not affect work.
She picked up the mirror and looked at her face. She found that it was as smooth as ever, and she couldn't help but smile happily.
Looking at Shen Xiaoyu, she has been taking close care of her for the past four days. Although she is a little tired, she has no signs of infection.
This is enough to prove that people vaccinated with cowpox are absolutely safe and will not transmit the virus to other people.
Outside the quarantine area, everyone else on the medical team is living like a year.
The only thing they could do was to keep praying, hoping that Lu An would be safe.
When Lu An walked out of the quarantine area with the support of Shen Xiaoyu, everyone felt that the sky was clearing up.
"Principal, it's great that you are okay!"
"Principal, what does it feel like to be vaccinated with cowpox? Is it dangerous?"
Lu An raised his hand to signal everyone to be quiet and make arrangements immediately.
"Now we still need some experimenters to test the effect of cowpox."
As soon as he finished speaking, almost everyone raised their hands.
Even Lu An is willing to take risks, so students like them must follow her example.
Lu An was very pleased with their bravery and named six of them.
"The dose you should vaccinate this time is smaller."
The punishment he suffered in the past few days made Lu An suspect that the amount of vaccination he had given was too large. Therefore, in this experiment, the amount of vaccination given to these six people was reduced a lot, and each person was different.
This is to try out the best dosage.
Six test subjects vaccinated with cowpox entered the quarantine area.
Sure enough, after reducing the dosage, their symptoms were much milder than Lu An's, and none of them fell into coma.
Some of them even moved around fine, just like normal.
Like Lu An, these six people were also quarantined for five days. When they came out, they were all alive and as strong as cattle.
At this point, everyone in the medical team has considerable confidence in the effectiveness of cowpox.
"Whether this method can prevent smallpox needs to be tested in practice. Come with me into the epidemic area."
Under the leadership of Lu An, seven people entered the 18th Regiment's station together.
And none of them had any protection.
Inside the headquarters of the 18th Regiment, there are now heavy clouds and a wave of sadness.
Wu Jinhua shed tears while looking at the white cloth covering the soldier's face.
For doctors like them, the saddest thing is that they tried their best but failed to save the patient's life.
They really worked hard and tried every means. Even if they saved far more people than died, the life of every Xia Army soldier was extremely precious.
"You have done everything you should do. As long as you have a clear conscience, these unfortunate soldiers will not blame you."
Wu Jinhua turned around in shock and saw Lu An standing beside her without any protection, and she exploded on the spot.
"Principal! Aren't you allowed to come in? Why don't you wear protective clothing or a mask?"
Lu An smiled slightly, calming her emotions.
"We have found a way to protect against smallpox, and we need to come here to test it. If it succeeds, we will no longer be afraid of this thing from now on."
Wu Jinhua burst into laughter and even felt slightly dizzy.
"really?"
“You’ll know once you try it.”
Lu An looked at Ma Shihua and Jiang Xiuyuan.
"You two, we still need to select some experimenters in your group to see if the method is feasible. We also ask for your help."
Maxhua immediately said: "Don't bother me, I'll just come."
Lu An was startled and quickly reminded him.
"This matter may be dangerous."
Maxhua's eyes widened.
"I don't know what danger is on the battlefield, so why should I be afraid of doing an experiment? You thief, if you have the ability, take me back. I will lead my troops to the sky, and I will kill you too!"
During this time, seeing so many soldiers losing their lives, Max Hua was really heartbroken.
Lu An gave him a serious look and admired such a strong man. She nodded, and a doctor came forward and began to inoculate Maxhua with cowpox.
A total of twenty test subjects were selected from the 18th Regiment. Together with the seven people from Lu An, they all removed their protection and began to move freely in the station.
One day, two days, three days...
Another ten days have passed.
All infected persons in the 18th Regiment's camp have completed treatment.
Some of them were cured, and some died unfortunately. But all eyes were focused on the experimenters.
During these ten days, they visited every corner of the entire station and even had close contact with infected people.
but……
There was nothing unusual about Lu An and others.
Not to mention being infected, there was not even a slight fever.
When the last patient was declared recovered, a big stone fell from Lu An's head.
"Report immediately to the superiors. The test is effective and smallpox can be cured."
The originally silent 18th Regiment station suddenly erupted into earth-shattering cheers.
From now on, the plague has finally been conquered by humans and can no longer wantonly take human lives.
Everyone understood the value and significance, and looked at Lu An and others with the highest respect.
This gentle and quiet little girl has become the incarnation of Guanyin Bodhisattva in everyone's minds.
The fact that cowpox can prevent smallpox was finally put on the desks of high-level officials.
"It's actually like this! It's actually possible! Hahahaha, this is great! It's great!"
Hou Xun, who has gone through great events without losing his temper, went wild for the first time in his life.
He was dancing and running around on the ground, not caring about his appearance at all.
In fact, he understood very well what it meant to defeat smallpox.
Zuo Mengeng was also relieved and regained his confidence.
In this troubled era, the Xia Kingdom finally came out.
"Immediately ordered to start vaccinia vaccination. In addition, an order was sent to all glass factories to suspend current production and go all out to ensure the supply of syringes."
The world is vast and the epidemic is the largest.
In order to eliminate the harm of smallpox, Zuo Menggeng used state power.
