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

Key figures

What the numbers say

In 2024, IDA only's immunization, HepB3 (% of one-year-old children) rose 0.31 percentage points on 2023 (from 75.37% to 75.68%).

Across the 30 yearly changes before that (1994 to 2023), the average change was +2.49 percentage points and a typical year strayed about 4.81 percentage points from that (the standard deviation). This year's change was 0.5 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 17.04 percentage points in 2007 and the biggest yearly fall was 2.74 percentage points in 2021. 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 the straight-line trend is downward, about 0.56 percentage points a year. A straight line explains 68% of the movement over 10 observed years.

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.
