National Influenza Vaccine Data

Data is collected from the National Immunisation Register (NIR), Covid Immunisation Register (CIR) and Aotearoa Immunisation Register (AIR) and is collated weekly. It is collected from three systems due to the variety of providers that administer Influenza (flu) vaccinations and their associated system compatibility.

We report both publicly funded and some privately funded flu vaccines that are recorded. Not all the privately funded vaccines are recorded in our registries which means the total number of vaccines administered will be higher than reported. Influenza vaccines are funded under several criteria, further details here: Influenza vaccine | Health Navigator NZ. Our reporting is focussed on the 2023 funded age group. Note that funding differs by ethnicity for the 55-64 year old group.

Definitions

Ethnicity: This is based on prioritised ethnicity, which means each person is only counted against a single ethnicity category. When a person has multiple ethnicities recorded, then the prioritised ethnicity is ranked in the order of 1) Māori 2) Pacific Peoples 3) Asian 4) Other/European. For example, if a person is recorded as their ethnicities being both Māori and Pacific Peoples, their prioritised ethnicity will be Māori, i.e. they will not be counted in the Pacific Peoples group.
YTD: is defined as vaccinations occurring in the 2023 flu season between 20 March 2023 and 15 September 2023.
HSU FY21/22: the HSU is an estimate of the population using the health system in New Zealand. A person is included in the HSU if they use health services (including births and deaths) in the reference period, or are enrolled in a primary health organisation (PHO) during the reference period. The reference period for the FY21/22 HSU is: 1/7/2021 and 30/6/2022.

Vaccinations by district

Number of vaccines by district and prioritised ethncity. Based on the district of where the person lives, which may differ from where the person received their vaccine.

Vaccination uptake: age 65+ years

Uptake percent is calculated by comparing the flu doses to date for this year with the estimated number of people in New Zealand who are aged 65 and over.

The estimated population is based on the most recent Health Service User (HSU) population, HSU FY21/22. The equity gap is the difference in rates for Māori or Pacific ethnicities to non-Māori/non-Pacific.

Vaccination uptake: age 55 to 64 years

Māori and Pacific Peoples aged between 55-64 are eligible to receive a funded flu vaccination. However, non-Māori, non-Pacific (NMNP) people of this age group are only eligible to receive a funded flu vaccination if they are health or disability care workers or have an eligible medical condition.

We have not reported an equity gap for the 55-64 year olds due to the difference in funding criteria.

Vaccinations per week for all age groups

Notes on report data:

Data is collected from National Immunisation Register (NIR), Covid19 immunisation Register (CIR) and Aotearoa Immunisation Register (AIR) and collated weekly.
Data captured on paper or systems other than NIR/CIR/AIR are not included.
The data contains public and privately funded influenza vaccinations. Following the 2021 flu season we have seen a higher proportion of privately funded vaccines being recorded. This is due to additional immunisation registries and the ability of pharmacies and other providers being able record vaccinations. Data between years, therefore, are not directly comparable
