Abstract
After introduction of a 3-dose childhood schedule of pneumococcal conjugate vaccine, rates of invasive disease decreased among children and non‐Aboriginal adults but increased markedly among young Aboriginal adults, which has resulted in an increasing disparity, in recent years, between Aboriginal and non-Aboriginal people, with respect to disease rates.
