In this paper, the development progress, advantages, and disadvantages of six new coronal vaccines including inactivated vaccine, nucleic acid vaccine, vector vaccine, protein subunit vaccine, live attenuated vaccine and virus-like particle vaccine was reviewed. The results of the novel coronavirus pneumonia in phase III clinical trials show that the new vaccine has good safety and immunogenicity. The approved vaccine has been proved to have good protective efficacy. However, attention should be paid to the adverse reactions of the vaccine and the long-term protective effect.
