Many people have a very obvious scar on their arms, this vaccine scar named "planting flowers", which is in people's subconscious cowpox, that is, the vaccine against smallpox. Pen, fun, and www.biquge.info

In fact, it is BCG, which is a vaccine used to prevent tuberculosis, using live, non-virulent bovine tuberculosis bacillus, which produces immunity to human tuberculosis bacillus by causing minor infection after inoculation in humans. More than 90% of the recipients will form ulcers at the site of inoculation for a few weeks to six months, and finally heal to form a scar, commonly known as stuck scar.

This scar is so similar to the scar of cowpox!

In fact, after 1984, newborns in the country stopped vaccinating their newborns, and only scientists who studied smallpox, specific health care workers, and other groups of people who might have been exposed to the virus were vaccinated! Because vaccinia vaccination can cause serious side effects. Although that's rare.

What if the smallpox virus makes a comeback? And what will happen?! Zhu Cheng had already imagined that scene!

The United States stopped smallpox vaccination in 1972, and after 20 years, the population no longer has any immunity to smallpox, and the vast majority of countries have stopped producing and stockpiling smallpox vaccines.

The smallpox vaccine is not derived from the smallpox virus, but from cattle. Discovered and prepared by the English physician Edward Jenner.

Vaccinia virus is a virus that causes minor cowpox lesions in cattle. If a person is infected with the virus, they will only experience mild discomfort and develop resistance against the vaccinia virus. Since the vaccinia virus has the same antigenic properties as the smallpox virus that causes smallpox disease in humans, people can also acquire immunity against smallpox virus after vaccinia vaccination.

And Zhu Cheng couldn't understand the reason why the smallpox vaccine was not destroyed. Why has this smallpox virus survived to this day?

The Centers for Disease Control and Prevention in Atlanta, USA, gave the reason for studying the smallpox virus, a virus unknown to humans, and published a new study in the journal Immunology in May 2010.

The other is the National Research Center for Virology and Biotechnology in Novosibirsk, Russia, and the reason they give is to protect biological diversity, in case there is a virus that humans cannot deal with, and it happens to be restrained by the smallpox virus? Who can say what the future holds?

He did not know why such a reason could be adopted at six international conferences! It's just that now the specimens and living organisms of this virus have reached his hands.

Cree's science center will be the third place in the world to preserve the smallpox virus. Zhu Cheng sighed and entered Omar's room, which was actually a warehouse. The home of the Cree housekeeping robot "Ron" was temporarily used.

Such a virus was actually taken out as a gift, simply as a name, it was too extravagant, Zhu Cheng had already felt the breath of conspiracy, he didn't believe that such an important thing would simply be taken by a folk rich man.

"Omar? I'm Zhu Cheng. When we meet for the first time, please take care of it. With a smile on his face, Zhu Cheng walked into the interrogation room, looking at Omar's unkempt hair, knowing that it was the result of a tiring journey.

"Although your people are very unfriendly, I still come with the greatest sincerity, I believe you have seen it." Omar stood up with his head covered. continued: "I don't know if you're satisfied with this gift? ”

Zhu Cheng naturally saw that these small bottles were labeled "variola", which is the scientific name for smallpox. How could he not recognize it, the gray-black reagent, black on a white background. He naturally knows what it is!

"Satisfaction is satisfaction, but I need to know how you got it? You must know that the smallpox virus is a thing of the United States, how can it be casually in your hands? "Zhu Cheng's town has a lot of meanings. Going back to before the founding of the United States and down to the current world hegemony, it all means something.

"World Association for the Advancement of Science, the price of your bribe! He wants you to join the World Association for the Advancement of Science! Be one of them! My little money is multiplied by ten, and I can't buy off the head of Lawrence Berkeley National Laboratory! You know, it's a laboratory under the U.S. Department of Energy, and the smallpox virus is also secretly preserved. Omar had a smile on his face.

"You know how powerful this association is, DDT, sugar, salt, and ethyl gasoline are all their products! Quite domineering to control the pace of science all over the world, this is a gift to invite you to join, and many more! As long as you want nothing you can't get! Omar described the association in an exaggerated tone because he was cornered by it.

"Are you trying to persuade me to join this promotion association?" He really gave it a serious thought, though it didn't take more than three seconds.

The expression on Omar's face was stunned, no matter how you look at Zhu Cheng, he is a fighter! The sudden hesitation at this moment made him blindfolded for a while.

"The smallpox virus is just one of the gifts, and they feel that an unknown virus that is extinct in the wild can open a channel of friendly communication. These gifts also include more than 50% equity in three listed companies! Ownership of three mega cruise ships! There are also three places for members of the US Congress! They are eager for you to join. The expression on Omar's face was more lonely than ever, and he thought he could be blessed here. I didn't expect to get such an answer.

"Actually, I don't dislike the association, I just think that one day they will sell me, I don't know yet. So let that Rausch's promotion meet the hell! Welcome to Cree, Omar, you're a talented and situational person. How is the research on the smallpox virus being conducted? Together with Yang Haibin. ”

Zhu Cheng naturally knew about Omar's experience, this Omar is a doctor who graduated from the University of Washington in the United States, a member of the National Academy of Sciences, and a professor at the University of Wisconsin-Madison. Since Omar has come to defect, let's make the most of it! Now he has nowhere to go except the mountain city.

"To comply with the security regulations of Career Biolabs, which are no better than Lawrence Berkeley National Laboratory, the security measures are taken care of by the artificial intelligence, which is directly responsible for me. Any small action has the potential to cause a chain reaction. You, don't make a mistake about yourself. Zhu Cheng gave a warning, Shancheng is his home field, and he is not afraid of this guy at all.

He walked out of the room where Lao Omar was imprisoned, and went to Yang Haibin's room, and saw this senior brother who had never met before, and his perception of this person was extremely complicated, and there were already two people here, Feng Feng and Qi Shuli.

The conversation between the three of them was relatively peaceful, there was no quarrel, and they talked about their recent situation. Hearing the news that the two had received their marriage certificates, Yang Haibin's tired face regained some smiles.

"Congratulations! At the beginning, I said that the child would recognize me as a godfather! Yang Haibin laughed and continued: "Is this our most promising little junior brother?" Sure enough, he is the leader of our department, and he is the first to lead in terms of size! ”

Zhu Cheng nodded, glanced at the winger, and motioned for the two of them to go out. The following content is not suitable for two people to hear, they belong to people who are obsessed with scientific research, and the treatment of Yang Haibin cannot bring much emotion.

When the two of them left the room, Zhu Cheng took out a document and said: "You have been away for 5 years, in fact, you shouldn't come back, if it weren't for Teacher Zhang to protect you this time, it is estimated that you should be in the interrogation room of MSS instead of here now." How do you feel about leaving resolutely back then, and now you are back in despair? ”

Yang Haibin leaned against the wall and asked, "Is there any smoke?" Get me one. I thought I was going to heaven, but I found it still on earth. ”

Zhu Cheng shook his head, how could they carry this thing on their student figures?

"Your processing result is here, this is the preferential treatment applied by Teacher Zhang, with my temper, you should go to the northwest to plant potatoes!" Zhu Cheng angrily threw a piece of paper to Yang Haibin! When he left, he ran away without saying a word, and Zhang Youlin even affected his normal promotion because of this.

This is an even worse situation for biological laboratories, which are already poorly funded. Although Zhang Youlin didn't say it, the funds were very tight during that time!

"Just go and go clean, what kind of ability is it to come back!" Zhu Cheng said a word and left the room, while Yang Haibin picked up the paper. This piece of paper is a statement on the restoration of his nationality, and he can rely on this statement to apply for a new household registration and identity card.

Zhu Cheng commanded a "Ron", ready to let Ron follow him day and night, the heart of harm is indispensable, but the heart of defense is indispensable! He was also worried that this Yang Haibin would run away when he came back and that set of materials. Omar is also treated in this way.

After the disturbance stopped, Zhu Cheng returned to the chairman's office, and Zhao Ling and Zhang Youlin were already waiting for him here.

"It's not worth being angry with someone like that, teacher." Zhu Cheng greeted Zhang Youlin first and continued: "The smallpox virus they sent is here. He took out a few dusty reagents from the safe behind him and handed them to Zhang Youlin.

"Smallpox, this disease has ravaged Europe many times in 300 years, and later scholars estimate that as many as 200 million people have died from this virus, a nightmare for mankind!" Zhang Youlin also sighed when he looked at the specimen.

"What I'm most afraid of is that someone will use him as a biological weapon, artificially create a plague, you must know that humans have little resistance to smallpox now!" Zhu Cheng's words couldn't hide the worry, what kind of catastrophe would this airborne virus be once it was released from the vault?

"Zhu Cheng, the front desk turned the phone and said that someone was calling to find you, from the United Kingdom. said that it was Liu Yiming's classmate. ”
