A milk-based self-assemble rotavirus VP6–ferritin nanoparticle vaccine elicited protection against the viral infection

摘要

BackgroundRotavirus is the leading cause of severe dehydrating diarrhea in young children and the inner capsid protein VP6 is a potential vaccine candidate that can induce cross-protective immune responses against different Rotavirus strains. The use of ferritin nanoparticles as the scaffold of the antigen can improve the immunogenicity of the subunit vaccines and provide broader protection. We here present a non-live and self-assemble recombinant rotavirus VP6–ferritin (rVP6–ferritin) nanoparticle vaccine.
