RECOMBINANT NOVEL CORONAVIRUS VACCINE USING REPLICATION-DEFICIENT HUMAN ADENOVIRUS AS VECTOR

Provided is a novel coronavirus vaccine using replication-deficient human type 5 adenovirus as a vector. The vaccine takes the replication-deficient human type 5 adenovirus that is lack of E1 and E3 in a combined mode as a vector, and HEK293 cells that integrate adenovirus E1 genes serve as a packag...

More Information
Summary:Provided is a novel coronavirus vaccine using replication-deficient human type 5 adenovirus as a vector. The vaccine takes the replication-deficient human type 5 adenovirus that is lack of E1 and E3 in a combined mode as a vector, and HEK293 cells that integrate adenovirus E1 genes serve as a packaging cell line, and protective antigenic genes carried are optimized COVID-19 (SARS-CoV-2) S protein genes (Ad5-nCoV). The vaccine has good immunogenicity in both mouse and guinea pig models and can induce the body to produce a strong cellular and humoral immune responses in a short time. Research on the protective effect of hACE2 transgenic mice shows that 14 days after a single Ad5-nCoV immunization, the viral load in lung tissues can be significantly reduced. It shows that the vaccine has a good immune protection effect against COVID-19.
