Because of the situation that Africa is about to fall, the World Health Organization also waved a big hand and agreed to Chen Chen's clinical trial without hesitation. There was no need to combine the four phases of the trial, but the four phases of the trial into one, and only the first phase of the clinical trial. .

　　 The so-called phase one and phase two here are the testing period of the vaccine. Generally speaking, a vaccine needs four phases of experimentation from development to market.

The first phase of the trial is mainly to test the safety of the vaccine. The trial can only recruit dozens of people at most. After being vaccinated, these people will be observed for several months, and the second phase will only be opened after the vaccine is confirmed to cause no harm to humans Periodic test.

　　In other words, the first phase of the trial only tests whether it is harmful to humans, and from the second phase, the vaccine is tested for effectiveness.

　　The third and fourth phases began to increase the number of people, and the observation time became longer and more strict.

It usually takes several years to complete the entire clinical trial, and there are even many vaccines that have not been made for decades, but there is also flexibility. For example, in the epidemic three years ago, it took only one year for vaccines in various countries to go from development to market. .

　　 This is related to the global situation. The more violent the virus rages, the faster the vaccine development.

After all, the daily number of infections and deaths in Africa is more than 100,000. It is hard to get a vaccine. After several years of clinical trials, the vaccines do not need to be marketed after they pass the clinical trials. They are all burned to fellow Africans. Sister is fine.

　　 Therefore, during this critical period, clinical trials of vaccines must be fast, and the sooner the better, even the World Health Organization has approved an indicator that allows such vaccines to have a small amount of harm to the human body.

　　 In other words, even if the vaccine developed by Chen Chen hurts part of the human body, it is acceptable, as long as the plague can be stopped.

　　 As the news of the BE-006 vaccine developed by the Life Science City spread to the world, countless people began to focus on the Life Science City.

　　 Under Chen Chen’s appointment and dismissal, Professor Bernhard was responsible for the operation of this clinical experiment, and the entire Life Sciences City has stopped all experiments, and the resources of the entire city are serving this clinical experiment.

　　 However, Chen Chen is still very confident about the effect of the vaccine, after all, it is a product based on the research of the entire hive laboratory.

You know, Umbrella Company has been studying the ancestor virus for thirty years, and even researched flowers, and the genetic similarity between BE-006 virus and ancestor virus is extremely high, coupled with the technological level of the hive, this vaccine is almost not There is a possibility of failure.

　　 So, after Chen Chen threw the clinical trial project to Professor Bernhard, he went back to the Spire Lab and began to study the initial progenitor virus.

　　 "The ancestor virus, but it has the power to evolve."

　　 At this time, in the Level 4 Biosafety Laboratory of the Minaret Experimental Base, Chen Chen was holding a blue Yingying test tube, showing the color of thought, "But this evolution is more like a mutation."

　　 said, he poured the liquid in the test tube into the human cell culture medium, and then silently observed.

　　 In this laboratory at this time, not only Chen Chen, but also Hannibal and Li Lei's team existed.

　　 There are several very complicated instruments around the laboratory. These instruments do not match the style of other instruments, and are more like a product of science fiction.

　　 These instruments are the ones that Chen Chen brought from the plane of Resident Evil. With these instruments, the biotechnology of the Spire Lab has been enhanced again.

　　 It can even be said that the Spire Laboratory at this time has exceeded the biological level of modern human civilization and has reached a higher level...

　　 "Mr. Chen."

　　 After a while, Li Lei suddenly exclaimed, "Come and take a look."

　　 Chen Chen heard the words and walked to the electron microscope and looked on the screen, but saw that the cells in the culture medium began to proliferate rapidly, like bulging bubbles.

　　 "The growth rate has increased from a coefficient of 1 to 3, which has more than doubled."

Li Lei was faintly excited, "Moreover, each time a cell divides, the length of telomeres hardly decreases. This is exactly the same as the description of the information you brought back. This virus really has the ability to enhance metabolism and extend lifespan. !"

　　 "Don't be too optimistic."

Chen Chen shook his head without any excitement. "Don't forget, this is just a change in the most ideal environment of a petri dish. In fact, if it is not in a petri dish, it happens in a normal person's body. Inside, I’m afraid this person is bleeding as much as he was infected with Ebola."

　　 "Because of a problem with the immune system?" Li Lei put away his smile upon hearing this.

　　 "Yes, there are symptoms in the data."

Chen Chen called up the information on the screen and said, "The ancestor virus contains a superantigenic toxin. If this virus does enter the human body, it will definitely attack the human immune system first, including lymphocytes, dendritic cells, and giant cells. Phages."

"And as shown in the culture medium, after this virus infects the human body, the human metabolism rate is increased to three times that of the previous one. This also means that humans need to consume a lot of nutrients. This consumption rate is simply not what humans can support. Started."

　　 "Therefore, the ancestor virus has a great defect and does not conform to our experiment."

　　 Li Lei nodded regretfully.

　　 "However, compared to the original progenitor virus, its advanced products are different."

　　 Chen Chen suddenly changed his words. He narrowed his eyes to look at the leech slices in the petri dish. “If you can fuse part of the leech gene fragments with the ancestor virus, you can get the famous T virus.”

　　 "Yes, the T virus is indeed better than the ancestor virus."

Hannibal on the side walked over and added while looking at the information, "The ancestor virus does have the ability to enhance human strength and speed~lightnovelpub.net~ and can even extend the lifespan of humans, but the price is extremely successful. low."

"Just like BE-006, the survival rate of infection with the ancestor virus is less than 10%, and even if you are lucky to survive in the end, you may not be able to be changed by the ancestor virus because the human body only produces antibodies and is immune to the virus. That’s all."

　　 "So the ancestor virus is actually not perfect, it still has great flaws."

"However, the T virus is different. This advanced version of the ancestor virus is different from the virulent virus BE-006, but a mild virus that co-exists for a long time by integrating its genetic material into the chromosome of the host cell. "

　　 "During this symbiosis, the host cell's genes are changed due to the integration of viral chromosomes."

　　 Talking, Hannibal raised his head, "In short, humans will undergo genetic recombination after being infected with this virus."

　　 Hearing this, Li Lei couldn't help frowning, "But why did human beings infected with the T virus not only have not evolved, but become zombies?"

　　 "That's because of the failure of evolution."

Chen Chen replied, "If you want to cultivate a creature that can truly fit the T virus, you must start from the fertilized egg. That is to say, you must use the T virus to infect the fertilized egg, so that the fertilized egg can grow into a real enhanced life and directly infect humans. The consequence of this is that evolution fails to become a zombie."

　　 "Of course there are exceptions to all of this."

　　 After thinking about it, Chen Chen added again, "Maybe one or two lucky people among millions of people can withstand the virus and become a superman like Alice..."
