Academician first test the first shot of vaccine "? Still have to wait until April!
On the evening of March 3, a picture with the text "Vaccine first shot, academician first try" appeared on social networks. The picture is believed to be that the vaccine developed by Academician Chen Wei's team has entered the clinical stage. The article also stated: "The first new crown virus vaccine was injected into Academician Chen Wei's left arm today. Seven members of the expert group also injected it together."
A compliment appeared online.
But shortly thereafter, the authenticity of this picture was falsified: "How could a human experiment with a vaccine be so fast?"
"Strict scientist, won't do it!"
"The picture starts with the content! It's very obvious that this picture was taken by Chen Wei before her departure in Wuhan ..."
"Carlyle", certified as the "Executive Editor-in-Chief of the Hong Kong Wen Wei Po Beijing News Centre" on Weibo, also posted a Weibo on the early morning of March 4th: "This photo circulated was before Chen Wei's departure to Wuhan. Is the same needle, designed to enhance immunity to the battlefield "" The text on these circulating pictures is incorrect. "
The appearance of the above picture may represent people's enthusiasm for the success of the vaccine.
The premise of "personal testing" is "entering the clinic"
"First of all, the expression of 'the first new crown virus vaccine' is not precise, and the words such as successful vaccine development cannot be used casually."
"A vaccine research and development cycle is very long," a researcher who is working on a vaccine for the new crown virus told China Science News.
The researcher who requested anonymity said that after the vaccine developed has entered the clinic, it still needs to undergo a process from small-scale population trials to large-scale trials. After the three-phase clinical trial, the relevant national drug review department can approve the marketing of the vaccine. "Vaccine" can really be called "vaccine".
So, what is the "personal test" in the vaccine development process?
"Only after the preliminary work of vaccine development, including industrial preparation production technology, animal-level effectiveness and safety evaluation, approval by the State Drug Administration, has been completed, and the candidate vaccine has been approved for clinical trials, can it begin Small-scale human clinical trials, at which time the head of R & D will be the "first vaccination."
The researchers said medical ethics would not be passable if these jobs were "tested" before they were done.
The anonymous researcher told China Science News: "Some vaccines are effective in animals, but not so effective in humans. Can this vaccine enter the clinic? So it is necessary to prove the effectiveness of the vaccine. "
"Injecting yourself does not mean you can inject it to the public." Another industry source mentioned: "It must be done according to regulations."
Fastest vaccine or "clinical trials begin in April"
In fact, on the evening of March 3, CCTV News Network just reported the relevant progress: "The scientific research team led by Chen Wei, an academician of the Chinese Academy of Engineering and a researcher at the Academy of Military Sciences, has made important progress in the development of the new crown vaccine.
Does this "important phase achievement" refer to the development of vaccines into human clinical trials? It was not mentioned in the news broadcast.
However, from the news that Academician Chen Wei “striving to bring the new recombinant crown vaccine under development to the clinic and its application in the shortest possible time”, the vaccine developed by her team has not yet entered human clinical trials.
On February 28th, five days ago, Premier Li Keqiang also listened to the accompanying academician's introduction to the research and development of vaccines when he inspected the National New Crown Pneumonia Drug Medical Device Emergency Platform.
In the academician's introduction, there was a clear point in time: "Every vaccine research and development team is racing against time and clock, and strive for the fastest vaccine to begin clinical trials in April".
On the other side, the reporter was informed that according to Qin Chuan, the director of the Institute of Medical Experimental Animals, Chinese Academy of Medical Sciences, on March 4, the Institute of Medical Experimental Animals is currently conducting animal experimental evaluation of six vaccines.
These 6 vaccines should be the fastest in China's new crown vaccine research and development. It is understood that at present only the institute (in cooperation with the Chinese Center for Disease Control and Prevention of Viral Disease Control and Prevention) has transgenic mice identified by the Ministry of Science and Technology. Two animal models of river monkey pneumonia infection model.
Should the vaccine be tried on academicians first?
The reason why many people are willing to believe that this picture is Academician Chen Wei's "first try first shot" is because Chen Wei is a female scientist who has made important contributions in the hard battles such as SARS and Ebola. During the Bola outbreak, she led a team to complete an Ebola vaccine clinical trial in an African epidemic area, the first Chinese vaccine to conduct clinical research abroad.
Chen Wei has long been engaged in the research of new biological defense vaccines and new biological drugs.
On the track of the development of the new crown vaccine, Chen Wei's team developed an adenovirus vector vaccine.
Today, its new crown vaccine development team is also regarded as a "seed player" for vaccine development.
In particular, as early as January 28, US President Trump announced at that time that American scientists would develop a new crown vaccine within 12 weeks, and Chen Wei chose a positive "gang": "I believe that the speed of our scientific researchers is no less than United States."
Although Academician Chen Wei ’s “Personally Tested Medicine” network diagram was rumored, some netizens expressed concerns about the R & D staff: “Why test the medicine (vaccine) in person? Such an important person needs to be protected. I can try it! "
Is it necessary for the person in charge of vaccine development to "test in person"?
On February 28, when inspecting the National New Coronary Pneumonia Drug and Medical Device Emergency Platform, Premier Li Keqiang asked whether the candidate vaccines that "start clinical trials in April at the earliest" are they safe? "
At that time, an accompanying academician in charge of vaccine research and development "revealed the scene" at the scene: "wait for the first vaccination when the vaccine is developed."
"This courage is a valuable character that our scientists dare to assume." Li Keqiang said at the time.
