Inactivated vaccine.

Three kinds of qualified COVID-19 inactivated vaccine products approved for marketing were produced by China Bio-Beijing Institute of Biological Products, Wuhan Institute of Biological Products and Beijing Kexing Zhongwei Biotechnology Co., Ltd., respectively. The principle is to use African green monkey kidney cells to culture and amplify the virus, inactivate the virus with β-propiolactone, retain antigen components to induce immune response, and add aluminum hydroxide adjuvant to improve immunogenicity.

Adenovirus vector vaccine.

Conditionally approved adenovirus vector vaccine is a recombinant COVID-19 vaccine produced by Kangxinuo Bio-stock Company. Its principle is to recombine novel coronavirus spike glycoprotein gene into replication-deficient human adenovirus type 5 gene, and the recombinant adenovirus expresses COVID-19 S protein antigen in vivo to induce immune response.

Recombinant subunit vaccine.

The recombinant subunit vaccine approved for emergency use this time is the recombinant COVID-19 vaccine produced by Anhui Zhifeilong Kyle Biopharmaceutical Co., Ltd. Its principle is to recombine the new coronavirus S protein receptor binding region gene into China hamster ovary gene, express it in vitro to form RBD dimer, and add aluminum hydroxide adjuvant to improve immunogenicity.
