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

Key figures

What the numbers say

In 2023, Nicaragua's immunization, HepB3 (% of one-year-old children) fell 3 percentage points on 2022 (from 92% to 89%).

Across the 23 yearly changes before that (2000 to 2022), the average change was +0.52 percentage points and a typical year strayed about 3.4 percentage points from that (the standard deviation). This year's change was 1.0 standard deviations below 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 7 percentage points in 2005 and the biggest yearly fall was 7 percentage points in 2004. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2014 to 2023 the straight-line trend is downward, about 1.19 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.
