Think of here!

Chen Cang is a little difficult to contain his inner thoughts.

He has been following up on the progress of the vaccine.

After all, it is the last link of the main task.

If this task is not completed, not only the reward cannot be settled, but the most important thing is that the subsequent main task may not know how long it will take to trigger.

After hesitation, Chen Cang directly chose to recruit!

[Ding! Use the recruitment order to successfully recruit vaccine experts!]

Before long, the voice of the phone remembered.

It''s Wang Zhen!

"Professor Chen, a foreigner has come to the Institute. He is looking for you!"

Chen Cang nodded. He didn''t expect the other party to come so soon!

But

Chen Cang suddenly thought of the fraud call.

Just when I wanted to transfer money, I received a fraud message and sent the card number.

Can''t it be such a coincidence?

"You wait first, I''ll be there later." Chen Cang decided to go later for the sake of insurance.

Xu Kun drives steadily and vigilantly, and has a good grasp of the tracked vehicles or any signs.

The car Chen Cang bought was a modified red flag, and Xu Kun drove it himself.

The car is not expensive. It cost hundreds of thousands of dollars, but basically the software and hardware engines have been replaced!

Xu Kun found someone to change them all.

It cost more than 20 million to refit.

Chen Cang never thought of this.

However, Chen Cang tried. The performance of the car is very good. It accelerates for 3.2 seconds after 100 kilometers. The suspension is also very comfortable.

Chen Cang is now more and more aware of the benefits of the recruitment order.

At the Institute, Chen Cang saw the man Wang Zhen said.

"Hello, Professor Chen, this is Kerry." Chen Cang is a little uncomfortable with his fluent Chinese and blonde western face.

However, Chen Cang looked at the other party''s information and was finally relieved.

[Kerry: recruiter, favorability: 100;

skill:

Immunology: Master

Vaccine research and development: quasi perfect level.

……】

Chen Cang was stunned!

Quasi perfect vaccine R & D skills.

That''s great!

Purple tokens are generally recruited with master skills. Chen Cang didn''t expect to be lucky this time and come up with a quasi perfect level!

Chen Cang hurriedly called the people to a meeting.

Introduce Kerry to everyone.

Subsequently, Chen Cang told the information brought by Tan Desai.

"Time is tight and the task is heavy!"

"We''ll work overtime during this period. We''ll solve the vaccine problem as soon as possible!"

"Otherwise, when winter comes, children''s diarrhea will only worsen. This time, rotavirus is threatening, and we can''t relax our vigilance!"

Everyone nodded.

After seeing the information brought by Chen Cang, we are really excited to tell the truth.

After all, the lack of core technology of vaccines is the root cause of their stagnation.

And the next few days.

Kerry''s ability was quickly recognized by everyone.

Even Chen Cang was foolish.

From how the vaccine works, to the classification of the vaccine, to the growth and reproduction of the vaccine, and finally to the use of the vaccine.

Kerry can do almost anything!

The emergence of Kerry has made up for the lack of some fragmented gaps in vaccine research.

However, rotavirus belongs to reovirus family, and there are 11 double stranded RNA fragments in its genome.

There are six structural proteins that play a key role!

That is, vp1-vp4, VP6 and VP7.

VP4 and VP7 constitute the glycoprotein and spike protein of the virus.

It is also the main means of virus infection!

Similarly, these VP4 and VP7 proteins are also the key to immunity.

If you can decipher VP4 and VP7 proteins perfectly, you will find a research method!

This involves the question of what a vaccine is?

Vaccine refers to vaccine preventive biological products used for human vaccination in order to prevent and control the occurrence and prevalence of infectious diseases.

These biological products refer to preparations prepared by microorganisms or their toxins, enzymes, human or animal serum and cells for prevention, diagnosis and treatment.

To put it bluntly, it is to inject attenuated viruses, bacteria or animal serum into the human body to make the human immune system produce antibodies.

Then, let the human body have the ability to fight these viruses!

The main problem of rotavirus is VP4 and VP7 protein!

At present, whether it is the pinnacle in the field of rotavirus research: pentavalent vaccine, mainly the G genotype vaccine of VP7 protein.

And the more in-depth study!

Chen Cang et al. Found that the mutated rotavirus mainly changed the VP4 protein without glycosylation modification.

and!

After Chen Cang''s disassembly of rotavirus RNA sequence, it was found.

Because the antibody level against VP4 protein is low after natural infection, and the interference of maternal antibody to VP4 protein based vaccine is also similar

For smaller.

Therefore, VP4 may be more suitable as a candidate antigen for rotavirus genetic engineering subunit vaccine than VP7 protein.

With the direction, the speed of research suddenly increased!

The research of the Institute is boring and wonderful.

Chen Cang''s rotavirus progress bar is improving every day!

[rotavirus vaccine: progress bar: 77%!]

Maybe it won''t take long to find the direction.

However, at such a time, Chen Cang''s phone suddenly rang.

Chen Cang looked. It was director Yu Yonggang.

After leaving the capital, Chen Cang did not contact director Yu for some time.

Why are you calling today?

"Director Yu? What''s the matter?"

Yu Yonggang heard Chen Cang''s voice and immediately smiled: "what have you been busy lately?"

Lao Yu''s voice is still like that, thick and full of spirit.

Chen Cang couldn''t help saying, "make a vaccine and be a father!"

Lao Yu laughed: "my big nephew, you have to watch it!"

"Vaccine? What vaccine?" Lao Yu suddenly changed his subject and couldn''t help asking.

Chen Cang explained: "about the rotavirus vaccine."

Lao Yu said, "are you busy? I said there was something I was going to recommend you. I almost signed up!"

"Fortunately, I called you and asked!"

Chen Cang suddenly became interested: "Oh? What''s up?"

Yu Yonggang said, "well, do you remember the quadrennial global first aid skills competition?"

"It will be held in March next year."

"Do you have a suitable team over there?"

Chen Cang was stunned.

First aid skills competition!

This competition is very famous in the circle.

Lao Yu and Lao Ma took part in 2020 and won the top 30, which is the honor behind!

It can be said that this is the Olympic Games in the field of first aid skills.

To tell the truth, Chen Cang wants to participate once.

But obviously, I don''t necessarily have a chance.

But

As the strongest person in emergency, shouldn''t he train the world''s first emergency rescue team?

[Ding! Trigger challenge task!]

[train an excellent first aid team to participate in the global first aid skills competition and win the championship!

When the task is completed, you will receive a reward: Golden recruitment order X5!]
