Publication number: 20240082387Abstract: The present invention relates to a fusion protein comprising a SARS-CoV-2-derived receptor-binding domain and a nucleocapsid protein, and the use thereof. The fusion protein comprising a coronavirus-derived receptor-binding domain and a nucleocapsid protein is highly applicable to a multivalent vaccine composition having greatly improved in-vivo half-life and remarkably superior efficacy compared to an immunogenic composition comprising only a receptor-binding domain. In particular, the fusion protein can greatly improve the titer of the coronavirus-specific antibody formation and T-cell immune response, and is thus useful for the prevention and treatment of coronaviruses comprising SARS-CoV-2.Type: ApplicationFiled: January 29, 2021Publication date: March 14, 2024Inventors: Myoung Ho JANG, Jae Chan PARK, Young Joo CHOI, Young Hyun PARK, Gil-Jung KIM, Seung Mi JEONG, Su Bin LEE
