As for medicinal herbs and the like, Bei Yutang had already prepared a lot of them, all for treating smallpox.
The most important thing is the vaccination against cowpox.
It would not be until a thousand years later that someone would discover that vaccination with cowpox could effectively prevent smallpox infection.
Cowpox is a less virulent form of smallpox that occurs in cows.
Vaccination with cowpox involves introducing the virus into the human body. Most people can survive this viral infection, and once they do, their bodies will produce antibodies.
Such a person would naturally be fearless when encountering smallpox. However, the cowpox method is feasible, but it also has dangers.
One of them is that if someone fails to survive the vaccination process, they will die.
Another disadvantage is that although people will basically not be infected again after encountering smallpox, this is only relative. There have been people in history who were still infected, but they are only a minority.
In addition to vaccination against smallpox.
There are two other methods in history that are equally effective and essentially similar, but compared with those two methods, vaccination with cowpox is the most effective.
Bei Yutang naturally doesn’t have cowpox, but the omnipotent system does.
"Ming. Give me the cowpox."
[Host, since you last asked about the types of cowpox, this system has done some research and found that there are indeed three types of cowpox for you to choose from.]
[One is common cowpox, which is moderately toxic. One is low-grade cowpox, which is highly toxic. The last is high-grade cowpox, which is the mildest. Host, which one would you like?]
"price?"
[Ordinary, ten points. Lower quality, five points. Higher quality, fifteen points.]
"Top quality." Bei Yutang said without thinking.
Ming was astonished. "Host, are you sure you want fifteen points? A small number of people can be vaccinated against cowpox. There are still millions of people in Yanzhou and even in Southern Tang. Are you sure you want fifteen points?"
"When did you start talking so much nonsense?" Bei Yutang asked back.
Ming suddenly stopped talking.
【Exchange successful.】
After Bei Yutang got the cowpox vaccine, he took eleven people to the ancestral hall.
Afterwards, he ordered people to isolate the entire ancestral hall and not allow anyone to enter or leave at will.
The eleven people, including the village chief, looked nervously at Bei Yutang, who was wearing white clothes and a mask.
"Now I'm going to vaccinate you one by one. Who's going first?"
"I'll go 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 he was done, the strong man was still confused.
"Is this all right?"
"Yes, all right."
The strong man said happily, "I'm fine."
Bei Yutang ruthlessly punctured his beautiful dream, "This is just the first step. Wait a few days, and it will be healed. Then it will be truly healed."
The strong man was confused.
Next, Bei Yutang vaccinated them one by one with cowpox, and then asked them to stay in their respective positions.
Everyone’s three meals a day are delivered by villagers outside, and no one can leave the ancestral hall.
That night, people began to have fever one after another.
"Sister Mu, the village chief has a fever." Daixiang shouted.
Everyone in the room heard the noise and looked towards the village chief. He was the first person to have a fever, and everyone gathered around him.
"What's going on?" someone asked.
"The effect is starting to appear." Bei Yutang explained in a low voice.
