There have been tremendous improvements in immunization coverage since
the Expanded Programme on Immunization was launched. We highlight
inherent challenges in measuring immunization coverage with precision as
coverage levels increase due to the sensitivity of coverage to the
accuracy of target population estimates. In fact, when comparing across
groups at high levels of coverage, error in target population estimates
can obscure differences in immunization coverage.
