National Health Commission: The safety and effectiveness of the new crown vaccine are supported by data

According to data released by the National Health Commission, as of April 3, a total of 136.

According to the technical route, the five vaccines are divided into three categories: one is inactivated vaccines, including three inactivated vaccines produced by Sinopharm Zhongsheng Beijing Company, Sinopharm Zhongsheng Wuhan Company, and Beijing Kexing Zhongwei Company; second, adenovirus The vector vaccine is a type 5 adenovirus vector vaccine produced by Tianjin Kangsino Company; the third is a recombinant protein vaccine, which is a recombinant new coronavirus vaccine (CHO cells).

What is the difference between the three technical routes?

"Inactivated vaccines are vaccines prepared through a series of purification techniques after the cultured and amplified live viruses are killed by physical and chemical methods.

"Adenovirus vector vaccines use type 5 adenovirus as a carrier, introduce new coronavirus antigen genes, and make a live vector vaccine through a bioreactor.

"Recombinant protein vaccines are genetically engineered to express the most effective antigen components in cells in vitro.

Which vaccine is more effective?

Wang Junzhi said that the three routes of new coronavirus vaccines have their own characteristics.

He Qinghua, the first-level inspector of the CDC of the National Health Commission, said that the current domestically marketed new crown virus vaccines have been reviewed and approved by the drug regulatory department, and their safety and effectiveness are supported by certain data, and they can be vaccinated with confidence.

How to choose single needle and double needle?

According to Shao Yiming, a researcher at the Chinese Center for Disease Control and Prevention, single-dose adenovirus vector vaccines are more suitable for people who need to go to the epidemic area for temporary or urgent tasks but do not have enough time to wait.

Single-dose vaccines also have disadvantages.
