Burke RM, Tate JE, Dahl RM, et al. - Researchers sought to compare T1D risk by rotavirus vaccination status among US children with commercial insurance. T1D may precipitate in correlation with rotavirus infection. Hence there may be an association between rotavirus vaccination and T1D. For example, Australian children younger than 5 years exhibited a decline in incidence of T1D after rotavirus vaccine introduction. However, no association of rotavirus vaccination with T1D risk in children 10 years and younger in 2 Finnish studies, although limited statistical power was reported in these studies.
