To nvestigate « up-to-date'and » age-appropriate indicators of preschool vaccination status and their implications for vaccination policy Methods.
The authors analyzec medical records data fron the Baltimore lmmunization Study for 525 2-year-olds born from August 1988 through March 989 to mothers living in low-income Census tracts of the city of Baltimore.
While only 54% of 24-month-old children were up-to-date for the primary series, indicators of up-to-date coverage were consistently higher. by 37 or more percentage points than correspond ng age-appropriate ndicators.
Almost 80% of children who failed to recelve the first dose of DTP or OPV age-approp ately fa led to be up-to-date by 24 months f age for the primary series.
Age-appropriate immunization indicators more accurately reflect adequacy of protection for preschoolers than up-to-date indicators at both the indivicual and population levels.
Age-appropriate receipt of the first dose of DTP should be monitored to identify children likely to be nde mmun zed.
Age-appropr ate ndicators should also be incorporated as vaccination coverage estimators in population-basec surveys and as quality of care rdicators for managed care organizations.
These changes would require accurate dates for each vaccination and support the need to develop population-based registries.
