Figure 5 - This figure shows all notified cases of IPD in non-Indigenous Australians aged 65 years or older in Australia between 2002 and the third quarter of 2013 by quarter and the serotype causing disease, grouped according to targeted vaccines. The figure demonstrates that while the burden of disease in this age group has remained relatively stable, the profile of serotypes causing disease has changed over time. Disease due to serotypes targeted by the 7vPCV has reduced substantially in this age group likely due to herd immunity impacts from the childhood immunisation program.
