WHO and UNICEF Immunization Coverage Estimates for Palau (2010-2021)

Key Information:

• Coverage estimates are derived from national reports, administrative data, and surveys with varying confidence levels.
• Disclaimer: Estimates are based on empirical data, and methodological challenges are noted (e.g., potential bias, lack of surveys, sudden declines).
• Source: Data as of July 7, 2022; next revision available July 15, 2023. More data available at:

BCG

Coverage stable at 99–100% for all years; estimated based on national reports. High confidence when surveys or registries were available.

DTP1 & DTP3

Coverage consistently high at 99% over all years.

• DTP3: Estimated from national data; confidence varies; often challenged (D-).

IPV1

Coverage fluctuated but mostly above 95%, available from 2015. Estimated based on national reports; confidence levels vary.

MCV1

• Inconsistent data; estimates range from 39% to 99%. High confidence only in years with survey data or national registry (e.g., 2014 survey).
• Notes: Some years excluded due to implausible data or interpolation.

HepB Birth Dose (HepBB)

Consistently high at 99% across all years, based on national reports or surveys. High confidence in data.

MCV2

Coverage low and inconsistent (35–98%), with estimates generally challenged (D-). Most years rely on national reports.

Survey Data (2014)

A survey among children aged 24–35 months provided specific coverage values:

• Hib3, MCV1, MCV2, PCV3, DTP3, HepB3, Pol3, RotaC: High confidence estimates ranging from ~76–95%.

Key Observations:

• Vaccines like HepBB, MCV1, DTP, and BCG show excellent coverage.
• Other vaccines (e.g., MCV2, MCV1, IPV, HepB3) have variable or lower coverage.
• Most estimates are challenged (D-R), indicating potential data limitations (e.g., ad hoc administrative data, interpolation, sudden declines).

All estimates should be used with caution and assessed for the specific context or objective.
