Immune Responses to Rotavirus Infection and Vaccination and Associated Correlates of Protection

Abstract
Group A rotavirus (RV) strains are a major cause of acute gastroenteritis (AGE) in infants and young children worldwide [1]. RV disease accounts for more than one-third of all diarrhea-related hospitalizations and 500,000–600,000 deaths per year [2–4]; most deaths occur in sub-Saharan Africa and Asia [3, 4]. Direct medical and indirect annual costs associated with RV disease are estimated to be €400 million in Europe [5–7] and to exceed US$ 1 billion in the United States [8].
