National Estimates of Reductions in Acute Gastroenteritis-Related Hospitalizations and Associated Costs in US Children After Implementation of Rotavirus Vaccines.

We compared acute gastroenteritis (AGE)-related hospitalization rates among children <5 years of age during the pre-rotavirus vaccine (2000-2006) and post-rotavirus vaccine (2008-2013) periods to estimate national reductions in AGE-related hospitalizations and associated costs. We estimate that between 2008 and 2013, AGE-related hospitalizations declined by 382000, and $1.228 billion in medical costs were averted.
