This figure shows all notified cases of IPD in non-Indigenous Australians aged 65 years or older in Australia between 2007 and the third quarter of 2016 by quarter and the serotype causing disease, grouped according to targeted vaccines. The figure demonstrates the burden of disease in this age group has increased in 2016 in this quarter compared to the first and second quarters of 2016, with non-vaccine serotypes associated with most notified cases. Disease due to serotypes targeted by the 13vPCV has reduced substantially in this age group likely due to herd immunity impacts from the childhood immunisation program.
