Figure 12b shows timeliness of the 2nd dose of MMR vaccine due at 18 months of age by Indigenous status for the cohort born July-December 2012, assessed in 2014. In contrast to the 2nd dose of MMR due at 48 months of age, timeliness of immunisation for the vaccine due at 18 months of age showed a much greater differential in delay in receiving this vaccine between non-Indigenous children and Indigenous children, with a 15.3% differential at < 19 months of age.
