Australia: Immunization, HepB3 (% of one-year-old children)

Key figures

What the numbers say

In 2024, Australia's immunization, HepB3 (% of one-year-old children) rose 1 percentage points on 2023 (from 94% to 95%).

Across the 22 yearly changes before that (2002 to 2023), the average change was +0 percentage points and a typical year strayed about 0.82 percentage points from that (the standard deviation). This year's change was 1.2 standard deviations above that average, so it was larger than a typical year, though not out of the range seen before.

On record, the biggest yearly rise was 2 percentage points in 2015 and the biggest yearly fall was 2 percentage points in 2010. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2015 to 2024 there is no clear straight-line trend: a straight line explains 11% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

What this measures

Child immunization rate, hepatitis B is the percentage of children ages 12-23 months who received hepatitis B vaccinations before 12 months or at any time before the survey. A child is considered adequately immunized after three doses.

Limitations: In many developing countries a lack of precise information on the size of the cohort of one-year-old children makes immunization coverage difficult to estimate from program statistics.

Regional and income-group figures are computed by the World Bank as a weighted average.
