The inactivated vaccine of Beijing Kexing Zhongwei Company was 9 1.25%, and that of Sinopharm Zhongsheng Beijing Company was 79%.
The second difference between Beijing Bio and Kexing vaccine: the approval time is different.
The inactivated vaccine of Sinopharm Zhongsheng Beijing Company was approved on February 30th, 2020, and the inactivated vaccine of Beijing Kexing Zhongwei Company was approved on February 5th, 20021.
Detailed introduction:
Both Beijing Bio and Beijing Kexing Zhongwei produce inactivated virus vaccine from COVID-19, and the research and development principles and technical routes are the same. At present, there is no test to prove that there is a significant difference between the protective effect and safety of these two vaccines.
As far as the safety factor is concerned, both vaccines are very high, because the efficacy, production technology and process of the two vaccines are the same. On the time of listing, Beiyao Bio is earlier than Kexing Zhongwei, and it is also the first COVID-19 vaccine approved for listing in China. Therefore, the vaccine should be injected as soon as possible with fewer side effects. Generally speaking, 28 days after injection, the human body can produce antibodies against COVID-19.
Although Kexing Zhongwei went public a little late, its safety factor and efficiency are not lower than those of Beijing Bio, and its side effects are very small. In short, no matter which of these two vaccines you have injected, you don't have to worry too much, because they are absolutely safe and effective. What we really need to pay more attention to is how to effectively enhance human immunity and reduce the harm of virus to human body.
