The world's first new crown inactivated vaccine international clinical (Phase III) trial officially launched

On June 23, the launch ceremony of China Pharmaceutical Group China Bionew Crown Inactivated Vaccine (Phase III) United Arab Emirates was held simultaneously by video conference in Beijing, Wuhan, United Arab Emirates, and issued a clinical trial approval document to Chinese biologyAt the ceremony, China and Afghanistan signed a relevant clinical cooperation agreement on the spot, marking the world's first new crown inactivated vaccine international clinical trial (Phase III) officially launchedZhang Wenhong, director of the infection department at Huashan Hospital affiliated with Fudan University in, said in an interview with people's daily that the current domestic epidemic control is very good, but that we have lost the opportunity to conduct phase III clinical research in China, if the new crown vaccine to do clinical research, to go abroad to the higher outbreak of the place to doclinical trials of the new crown vaccine, the subjects needed should be healthy people, why should clinical trials be done abroad?the virus "test" vaccine to be effective
" Phase III clinical trial is intended to verify the effectiveness of the vaccine, must give people who have been vaccinated to the opportunity to be exposed to the virus in order to determine whether the vaccine is effectiveEven if antibodies are detected in the body, it does not mean that the vaccine is effective and must withstand the virus's 'test'Zhang Hongtao, an associate professor at the University of Pennsylvania School of Medicine, told the Health Timesfor example, in areas where the virus is endemic, choose volunteers living in the same area, one group is vaccinated, the other group is not vaccinated, and in the face of the same risk of infection, the number of infected volunteers is significantly lower than that of unvaccinated volunteers, and the vaccine may be effectiveWithout the conditions for a virus epidemic, the vaccine cannot be proved to be effectiveto the outbreak of high-risk testing is the inevitable choiceZhang Hongtao believes that at present, China has fewer infected people, while more scattered, accumulation to a certain sample size is more difficultEven if customs officers or medical personnel are recruited for vaccination, the relative proportion is still relatively small and requires a sufficient amount of time to assess the effectthe final result of the general Phase III clinical trial is the scientific basis for the vaccine's approval to go on the marketVaccine clinical trials are a scientific issue, in the current situation, in order to verify the effectiveness of the vaccine as soon as possible, to conduct clinical trials abroad is an inevitable choice it is understood that the new crown vaccine developed by Chen Wei's team of Chinese Academy of Military Medical Sciences has been approved for clinical trials at The Ministry of Health of Canada This follows the success of the recombinant Ebola vaccine (rAd5-EBOV), developed by Chen Wei's team, in a phase II 500 clinical trial in Sierra Leone, Africa, the first Chinese vaccine to conduct clinical trials outside China Source: Phoenix
