Abstract
There is substantial evidence for broad cross-reactive immunity and heterotypic protection among human rotavirus strains in children with natural infection or with monovalent Rotarix vaccination. In this commentary, we addressed this same question by testing sera of guinea pigs and gnotobiotic piglets that were intramuscularly immunized with an inactivated human rotavirus vaccine and also demonstrated a broad cross-protective immunity among human rotavirus strains. Our findings from a single human strain in animal studies bode well for a low cost and efficacious inactivated vaccine to protect children against rotavirus disease throughout the world.
