Thinking of this!

Chen Cang had a little difficulty in curbing his inner thoughts.

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

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

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

After hesitating for a while, Chen Cang directly chose to recruit!

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

Not long after, the phone sounded.

It's Wang Zhen!

"Professor Chen, a foreigner came to the institute and is looking for you!"

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

but……

Chen Cang suddenly thought of a scam call.

Just when I was about to transfer money, I received a fraudulent text message and sent my card number.

It's not such a coincidence, right?

"You wait first, I'll arrive later." Chen Cang decided to go there for safety reasons.

Xu Kun drove steadily and was very alert, and could have 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 to the modification himself.

The car is not expensive and costs hundreds of thousands of yuan, but basically all the software and hardware engines have been replaced!

All of them were asked by Xu Kun to change them.

It cost more than 20 million to modify it.

This is something Chen Cang could never have imagined.

However, Chen Cang tried it and the car's performance was very good, with 3.2 seconds acceleration from 100 km/h and comfortable suspension.

Chen Cang is now increasingly aware of the benefits of the recruitment order.

When he arrived at the research institute, Chen Cang saw the man Wang Zhen said.

"Hello, Professor Chen, I am Carrey." Chen Cang was a little uncomfortable with the smooth Chinese language and the blonde and blue-eyed western holes.

However, Chen Cang looked at the other party's information and finally breathed a sigh of relief.

[Carry: Recruiter, favorability: 100;

Skill:

Immunology: Master

Vaccine development: Quasi-perfect level.

...】

Chen Cang was stunned!

Quasi-perfect level vaccine development skills.

It's so cool!

Purple tokens generally recruit master-level skills. Chen Cang didn’t expect that this time he was lucky and came out with a quasi-perfect level!

Chen Cang quickly summoned everyone to a meeting.

Introduce Carrey to everyone.

Afterwards, Chen Cang told the information brought by Tedros.

"Time is tight, the task is heavy!"

"We work overtime during this period, and we will solve the vaccine problem as soon as possible!"

"Otherwise, after winter comes, diarrhea in children will only worsen. This time the rotavirus is coming in full force, so you can't relax your vigilance!"

Everyone nodded.

After seeing the information brought by Chen Cang, everyone was really excited to be honest.

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

And the next few days.

Carrey's ability was quickly recognized by everyone.

Even Chen Cang was stunned.

From how vaccines work, to vaccine classification, to vaccine growth and reproduction, and finally to how to use vaccines.

Carrey can do almost everything!

The emergence of Carrey has made up for the shortcomings of some fragmented gaps in vaccine research.

However, rotavirus belongs to the Reoviridae family, with 11 double-stranded RNA fragments in the genome.

There are six structural proteins that play a role!

That is VP1-VP4, VP6, VP7.

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

It is also the main means of infection!

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

If the VP4 and VP7 proteins can be perfectly deciphered, we have found a research method!

This involves the issue of vaccines?

Vaccines refer to vaccine-based preventive biological products used for human vaccination in order to prevent and control the occurrence and epidemic of infectious diseases.

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

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

Then? Let the body have the ability to fight these viruses!

What rotavirus mainly needs to solve is VP4 and VP7 proteins!

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

And the more you study it!

Chen Cang and others discovered that this time the mutated rotavirus mainly changed the VP4 protein without saccharification modification.

and!

After Chen Cang's study on the disassembly of rotavirus RNA sequences, it was found.

Because the levels of antibodies against VP4 protein are low after natural infection, and the interference of parent antibodies to VP4-based vaccines is also similar

For smaller.

So compared to VP7 protein? VP4 may be more suitable as a candidate antigen for rotavirus genetically engineered subunit vaccine.

With the direction, the speed of research has suddenly increased!

The research at the institute is boring and exciting.

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.

But? Just at this moment? Chen Cang's phone suddenly rang.

Chen Cang looked at it and it was Director Yu Yonggang.

After the capital parted, Chen Cang did not contact Director Yu for a while.

Why did you call today?

"Director Yu? What's wrong?"

Yu Yong just heard Chen Cang's voice? He immediately laughed: "What are you busy with recently?"

Lao Yu's voice was still the same, full of thick and strong energy.

Chen Cang couldn't help but say, "Get vaccines and be a dad!"

When Lao Yu heard this, he laughed: "My eldest nephew, you have to be optimistic!"

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

Chen Cang then explained: "About the rotavirus vaccine."
