In the final analysis, it is the infection of cowpox that activates the body's immunity to this virus. Although it is known that cowpox can prevent smallpox, but to what extent it is considered successful, Leng Feng does not count.

There is no shortage of brave students in Lao Sun's medical school, and there is no shortage of soldiers who forget to die in the army of the Tang Dynasty.

Almost as soon as Leng Feng's words fell, everyone raised their hands.

"Protector, I'm coming!"

"We're not afraid, Protector, let me come!"

....

Ignoring those students and soldiers, Leng Feng pressed Li Shimin's arm beside him: "What are you making a fuss about!" ”

Li Shimin raised his other hand: "I plan to go to Zhuzhou and my party, no matter how bad it is, I can also be a peripheral commander." So, the first batch is still for me to come. ”

No one dared to let the Emperor Taishang do experiments, even Leng Feng was afraid that Li Shimin would make a mistake, so he got him to the second batch strongly. Even if he wants to be vaccinated, he must be sure that there is no major reaction.

Five students, five soldiers, plus Sun Simiao himself, a total of eleven people, this is a person with different heights, shortness, fat and thinness, and a big difference in age. In this way, it is convenient to analyze the factors that affect immunity.

Although Sun Simiao has studied sores, because he is properly protected, he has not been infected, and he has no antibodies so far. Originally, Leng Feng also wanted Sun Simiao to go to the second batch, but after all, he couldn't compete with his request.

For sores, or all infectious diseases, Sun Simiao is extremely hateful. In his early years, his family died in the plague.

After disinfecting everyone's arms, Leng Feng mercilessly cut open their skin and smeared the collected cowpox slurry.

In order to determine the amount of application, everyone's dosage is different, the most ruthless is Sun Simiao, seeing that Leng Feng refused to add more to him, he operated on himself and applied it four times.

After putting on the bandage, Sun Simiao let out a sigh of relief and said, "I hope you have enough of it!" ”

Eleven people from their experiments were admitted to wards, isolated from each other, and medical school students recorded their temperatures. Until now, Yan Liben couldn't make the kind of thermometer that Leng Feng wanted, so the way to feel the patient's body temperature was to touch his body.

Outside the ward, looking at Sun Simiao, who was bored reading inside, Li Shimin asked Leng Feng worriedly: "Can it be done?" ”

Although he was full of confidence in Leng Feng, he still knew how terrible the sores were.

Leng Feng shrugged, still unsure. For medicine, he is a half-ass, and out of rigorous considerations, he didn't even tell Sun Simiao too much. But now that he has to face sores, he can only move out his half-baked medical skills.

Cowpox is the bovine smallpox virus, and for this thing, Leng Feng only knows that it can make people gain antibodies against the smallpox virus, but the rest does not know anything.

Although Zhuzhou is critical, it is the most important thing to determine the dose and determine the harm now. Only a team that can resist the sores can provide enough help to Zhuzhou.

Sun Simiao's ruthlessness was effective, and among the eleven people, he was the first to have pimples on his body. On the third day, including the man who had only been stabbed once, he also developed pimples. On the fifth day, their herpes grouts formed pustules. At the same time, inevitably, everyone began to have a fever of varying severity.

It wasn't until everyone had pustules that Leng Feng was sure that a single wound would be enough for the vaccinia.

In five days, Li Chengqian mobilized all the forces of Datang and raised enough sick cows. And Leng Feng led the medical students to inoculate all the soldiers and medical students with cowpox. At Li Shimin's strong request, Leng Feng could only inoculate him.

Although the inoculated cattle are barely enough, Leng Feng still did not let Li Chengqian stop the recruitment of sick cattle, since the use of cowpox has found a way, so when will it not be for the family to be vaccinated? What's more, the sores in the grassland are not uncommon, and the border army also needs to be vaccinated.

If you want to completely remove the sores from Datang, I am afraid it will take many years of hard work.

Fever is easy to manage, as long as it is not a very high body temperature, just leave it alone, only overheated ones need to be cooled down.

When all the people who went to Zhuzhou were vaccinated with cowpox, Leng Feng ordered the extraction.

As long as the symptoms subside on the road, there really can't be delayed in Zhuzhou.

Li Shimin insisted on going to Zhuzhou together, which made Li Chengqian extremely helpless. When he went out in person, and even when the queen mother moved out, he was defeated.

The army started, and Li Shimin not only followed as he wished, but also brought Li Tai with him.

On the twentieth day before the start of the experiment, all the blood scabs on Sun Simiao's body fell off, leaving some pockmarks, but these traces would slowly fade over time. Compared to the horror of the sores, this pockmarked point is really nothing.

When he arrived in Zhuzhou, the old man suggested that he send a group of people to contact the patient first. Although the army has been inoculated with cowpox, it is still unknown whether it will work. ”

The army travels, everything is simple, even Li Shimin can only take a bare carriage.

Leng Feng was originally riding a horse, but was called to the carriage by Lao Dao to chat.

"I'm okay with that, the necessary experiments are right. Our Dragon Tooth Guard, Zuowu Guard, plus the students of the medical school, our escort, I am afraid there are 30,000 people. The lives of 30,000 people are not child's play! ”

Lao Dao nodded, then closed his eyes and revisited his prescription.

There is no cure for sores, and the patient can only rely on his own body resistance to stiffen it. However, with Sun Simiao's presence, it can still help patients increase their chances of survival. According to his understanding, although the sores are terrible, the fatality rate is not 100%, and the people who die are more likely to be complications caused by the virus.

Seeing that Sun Simiao was closing his eyes and recuperating, Leng Feng and Li Shimin's father and son consciously moved to the back of the car to avoid disturbing him.

slapped Li Tai on the head, and Leng Feng said helplessly: "Aren't you studying things?" Why do you have to come along? ”

Li Tai was vaccinated with cowpox before leaving, and there were still a few pox on his face at this time, so in order to avoid infection, he could only wear a mask.

Taking off his mask, Li Tai glanced at Li Shimin helplessly: "The royal brother is worried about his father, the queen mother is worried about his father, and I am also worried about my father, so I can only follow." Besides, with me here, there must be a place that can help you, Master. ”

Li Shimin enjoyed the care from his son very much, and said to Li Tai: "It's a good thing that you came, as long as the disaster in Zhuzhou passes, your name will spread all over the Tang Dynasty." Combined with your previous reputation, although you are not an emperor, you still can't run away from the title of a scholarly master. If you want your doctrine to spread to the Tang Dynasty, you can't do it behind closed doors, and occasionally you have to do things that move the world. ”
