A milk-based self-assemble rotavirus VP6–ferritin nanoparticle vaccine elicited protection against the viral infection
Abstract Background Rotavirus 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 scaffo...
