Special Note for the April 2008 Revision

The Centers for Disease Control and Prevention, National Center for Immunization and Respiratory Diseases is issuing revised estimates from the National Immunization Survey (NIS) of childhood immunization coverage for the year 2006. These revisions result in a minor change in the estimated percentage of children who are up-to-date with respect to the 4:3:1:3:3:1 series. The original estimate of 77.0 percent has been revised to 76.9 percent, a difference of one-tenth of one percent. For the majority of states and areas, revisions are similarly small; there are nine states that will experience larger differences, with the largest differences being in the range of 2 percentage points. Revisions for other vaccines and vaccine series at national, state, and area levels are of similar orders of magnitude. All revisions are within the margin of error of the survey. Users of the NIS data should be aware that the revision only affects the survey’s estimation procedure – none of the items of data actually collected in the survey are revised.

The 2006 NIS includes children born within a reference period of January 6, 2003 to January 6, 2005. In order to design sampling weights, the NIS depends in part on counts of live births by area and state obtained from the National Vital Statistics System. This revision of the 2006 NIS estimates is being made to address 690,965 births (out of a total of 5,867,674 births during the reference period) for which race/ethnicity information appeared to be missing from the vital statistics. The births with missing information were confined to nine states: Florida, Idaho, Kentucky, New Hampshire, New York, Pennsylvania, South Carolina, Tennessee, and Washington. In cases where birth records were missing race/ethnicity information, statistical assumptions were made to enable NIS estimation to proceed. Such assumptions, made using a scientific methodology called imputation, are employed when actual data are unavailable.

Subsequent documentation from the National Vital Statistics System revealed the existence of actual race/ethnicity data for a portion of the births for which such statistical assumptions had been made. As actual data are preferred, we have re-calculated the weights and have adjusted the estimates to account for this information. While adjustments are small, the National Center for Immunization and Respiratory Diseases is issuing these revised estimates to ensure that it continues to provide the highest quality information available to support programs that use NIS data.
