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

Key figures

What the numbers say

In 2024, Bolivia's immunization, HepB3 (% of one-year-old children) fell 8 percentage points on 2023 (from 67% to 59%).

Across the 23 yearly changes before that (2001 to 2023), the average change was −0.43 percentage points and a typical year strayed about 3.59 percentage points from that (the standard deviation). This year's change was 2.1 standard deviations below that average, so it was unusually large compared with the rest of the record.

On record, the biggest yearly rise was 5 percentage points in 2009 and the biggest yearly fall was 8 percentage points in 2019. 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 3.22 percentage points a year. A straight line explains 93% of the movement over 10 observed years.

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

A straight-line projection, tested first

Extending that straight line gives about 54.6% for 2027. We show this only because the same method, fitted on earlier years, predicted 2022 to 2024 better than "no change" would have: its average miss was 2%, against 5% for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

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.
