This figure shows the rate of IPD in non-Indigenous children aged less than 5 years from 2002 to 2010, by Indigenous status and age subgroups (less than 12 months, 12 to 24 months and two to four years). The rate of IPD in non Indigenous children decreased following the introduction of the universal 7vPCV immunisation program in 2005 in all three subgroups and has remained steady since then.
