This is an observational, single-center, cross-sectional study about adherence to both obligatory and recommended vaccination in children with Type 1 Diabetes Mellitus and their siblings.
A great amount of discussion has been made regarding the possible association between routine vaccinations and the risk of childhood type 1 diabetes mellitus. This study is designed to explore the level of compliance to obligatory and recommended vaccinations in children after being diagnosed with Type 1 Diabetes Mellitus and their siblings.
3,522 studies on the registry are indexed under Diabetes Mellitus, Type 1; 577 are open to participants now.
