At present, it has been reported that the vaccine for the new coronavirus has entered the phase I clinical stage, the vaccine for the new coronavirus is coming out, but it has not yet entered the stage of clinical use. The development of a general virus vaccine is divided into the following phases: Firstly, it is necessary to screen the vaccine’s virulent strain, and after obtaining the virulent strain, the clinical researchers have to use basal cultivation or cell culture to proliferate the virus and build up a seed bank of the virus. Second, enter the clinical research stage, researchers should carry out a series of physical and chemical and biological tests on the vaccine to determine the antigen content of the vaccine, mainly through volunteers to vaccinate, to evaluate whether the vaccine is safe, has entered this stage, if the vaccine has been tested for safety, in order to evaluate whether the vaccine is effective, it is necessary to study and assess the vaccine is not able to stimulate the body to produce protective antibodies after vaccination. Thirdly, to evaluate the effectiveness of the vaccine in the event of an outbreak. Thirdly, to evaluate the comparison between the vaccinated population and the unvaccinated population in the event of an epidemic, and to observe whether the vaccine is protective for the vaccinated population after the epidemic, the vaccine will finally enter the stage of real clinical use, which will take 1-3 months.
