Basic Facts

Stage of development

Implemented

Potential or current usage

This measure has been part of the PHO Performance Programme's National Indicator Set since 1 January 2006 and is used to measure how many people 65 years of age and over have had an influenza vaccination within the current influenza campaign.

Brief overview of the measure

General description

This measure focuses on how many people 65 years of age and over have had an influenza vaccination within the current influenza season campaign.

Rationale for selection

The complications of influenza (more commonly known as ‘flu’) in the elderly can be serious or life threatening. As a result, the Government funds the cost of influenza vaccines and their administration for people aged 65 and over and people of any age with certain chronic conditions. Only vaccinations provided to people aged 65 and over are counted by the Programme.

Target population

All people aged 65 years and over All people aged 65 years and over who are within the high need population (identified as Māori, Pacific Island and/or Decile 9 or 10)
