Chapter 2972 The Real World 335
As for medicinal materials and the like, Bei Yutang had already prepared a lot, all of which were used to treat smallpox.

The most important thing is the vaccinia.

It will be 1000 years in the future that someone will discover that vaccination with vaccinia can effectively prevent smallpox infection.

Cowpox is a form of smallpox that occurs in cattle and is less virulent than smallpox.

Vaccination is to put this virus into the human body.This kind of viral disease can be passed by most people. Once passed, antibodies will be produced in the body.

Such a person is naturally fearless when encountering smallpox.But the method of cowpox is feasible, but it is also dangerous.

Among them, if someone fails to carry it through the vaccination process, he will die.

Another disadvantage is that although people who encounter smallpox will basically not be infected again, this is only relative, and there will be people who are still infected in history, but this is only a small number.

In addition to vaccination against smallpox.

There are two other methods in history, which are equally possible, and their essence is similar, but compared with those two methods, vaccination with vaccinia is the most effective.

Bei Yutang naturally doesn't have cowpox, but the omnipotent system does.

"Ming. Give me the cowpox."

[Host, since you asked about the types of vaccinia last time, this system specifically checked it out, and there are really three types of vaccinia for you to choose from. 】

[One is common vaccinia, which is moderately toxic.One is inferior vaccinia, which is highly toxic.The last type is the superior vaccinia, which is the least toxic.Host, which one do you want? 】

"price?"

[Ordinary, ten points.Inferior, five points.First class, fifteen points. 】

"Master." Bei Yutang said without thinking.

Ming was very surprised, [Host, are you sure you want fifteen points.Not many people get vaccinated with one serving of vaccinia.There are tens of thousands of people in Yanzhou, and even the Southern Tang Kingdom. Are you sure you want [-] points? 】

"When did you talk so much nonsense?" Bei Yutang asked rhetorically.

Ming suddenly stopped talking.

[Successful exchange. 】

After Bei Yutang got the cowpox, he took eleven people to the ancestral hall.

Afterwards, people were ordered to isolate the entire ancestral hall, and no one else was allowed to enter or leave at will.

Eleven people, including the village chief, looked nervously at Bei Yutang, who was wearing white clothes and a mask.

"Now I'm going to inoculate you one by one, who will come first?"

"I'll come first." A strong man came out first.

Bei Yutang took out the cowpox exchanged from the system from a sealed jar, and began to vaccinate him. After finishing, the strong man was still stunned.

"Is that all right?"

"Yes, all right."

The strong man said happily, "I'm fine."

Bei Yutang ruthlessly pierced his sweet dream, "This is still the first step. After a few days, it will be better, and it will be really better."

The strong man was dumbfounded.

Next, Bei Yutang inoculated them with vaccinia one by one, and then let them stay in their respective positions.

Everyone's three meals a day are provided by the villagers outside, and no one can leave the ancestral hall.

That night, people began to have a fever one after another.

"Sister Mu, the village chief has a fever." Dai Xiang shouted.

After hearing the voice, everyone in the house looked at the village head.The village chief was the first to start a fever, and everyone gathered around him.

"What's the matter?" someone asked.

"The effect has begun to appear." Bei Yutang explained in a low voice.
