Australian researchers have made a link between the introduction of routine rotavirus vaccination for babies and a drop in the incidence of type 1 diabetes in younger children.

While cases of type 1 diabetes have been rising in Australia and worldwide over the past few decades, a Melbourne study has found the rate declined in children aged 0-4 from 2007, the year the oral rotavirus vaccine was introduced to the National Immunisation Program for infants aged between six weeks and six months.
