Impact of Rotavirus Vaccination on Hospitalisations for Rotavirus Gastroenteritis in Children Aged <5 Years in Australia

Existing computerised administrative databases from the Australian Institute of Health and Welfare (AIHW) will be reviewed to retrieve data on all-cause gastroenteritis/ rotavirus enteritis and bronchiolitis hospitalisations of children \<5 years in all the states using Rotarix from 1998 to 2009. Data from Australian Childhood Immunisation Register (ACIR) post introduction of rotavirus vaccines in the National Immunisation Program (2007 to 2009) will also be used.
