Third and fourth-born children less likely to have on-time vaccinations
Third and fourth-born children are less likely to be vaccinated on time than their older siblings. Also at risk were children of Aboriginal and Torres Strait Islander descent, premature babies, or those born to younger or smoking mothers. Combining immunisation, pregnancy, and birth records for almost two million Australian children, the Population Health Research Network’s data can help health authorities to promote childhood vaccinations in vulnerable communities.
