When will the new crown vaccine be available? What trials are to be completed in Phase III clinically?

Guide: Three of the five vaccines approved for clinical trials completed Phase II clinical trialsrecently, the new crown pneumonia vaccine production emergency standards, at the same time, five approved clinical trials of three of the vaccine completed the second phase of clinical trialsIn the event of a particularly significant public health event, the emergency use of the vaccine can be initiatedwhat trials will be completed in phase III of the new coronary pneumonia vaccine? How long will the vaccine take for the vaccine to be put into use? Wang Junzhi, vice-chairman of the group of experts and academician of the Chinese Academy of Engineering, gave authoritative answersReporter: What is the effect of the first phase ofclinical trial? What is the effect of phase II clinical trials? What is the goal of the next three clinical trials?Wang Junzhi, vice chairman of the group of experts on vaccine research and development of thejoint prevention mechanism, chinese Academy of Engineering academician: "the first phase of clinicalis mainly the observation of safety indicators;Reporter: what's the protection rate of the vaccine?Wang Junzhi: "
is the number of people who used the vaccine, after a epidemic cycle of infection and the number of people who did not use the vaccine, the number of people who developed the disease without a placebo, the resulting rate of protection."phase II clinical trial results show edifying safe and effectivein terms of vaccine effectiveness, the second phase of clinical trial results of the new coronavirus inactivated vaccine developed by the Chinese Biological Wuhan Biological Products Research Institute showed that the rate of neutralizing two doses of neutralizing antibodies after two doses was given in accordance with the two-injection interval of 28 daysWang Junzhi,: After statistical analysis of the results, the results reached the expectations and targets of our design in terms of safety indicators and effectiveness indicators It has laid a good foundation for the third phase of clinical development Although Phase II clinical trials initially suggest that the new crown vaccine developed is safe and effective, the protection rate is still needed to complete Phase III clinical trials, that is, to allow the vaccine to complete a pandemic cycle of effectiveness testing in the endemic region Wang Junzhi: The new crown vaccine must be done in the epidemic area to complete the third phase of clinical, the process will take some time no difference in antibody response from different sources of new coronavirus estocence for slightly different reports on new coronavirus strains in Asia, Europe, North America and other places, whether the vaccine is effective worldwide, Wang Junzhi said, in terms of vaccine effectiveness, there are no reports of different sources of new coronavirus and vaccine antibody response differences, the effectiveness of the new coronavirus for different sources of the virus in the world needs further research in clinical trials .
