Immunization registry use and progress--United States- 2001.

Immunization registries are confidential- population-based-

computerized information systems that collect vaccination data

about all children within a geographic area. Registries are key

tools used to increase and sustain high vaccination coverage by

providing complete and accurate information on which to base

vaccination decisions. Registries consolidate vaccination records

of children from multiple healthcare providers- identify children

who are due or late for vaccinations- generate reminder and recall

notices to ensure that children are appropriately vaccinated- and

identify provider sites and geographic areas with low vaccination

coverage. One of the national health objectives for 2010 is to

increase to 95% the proportion of children aged <6 years who

participate in fully operational population-based immunization

registries (objective 14-26). CDC analyzed data from 50 states and

the District of Columbia (DC) from the calendar year 2000

Immunization Registry Annual Report (CY 2000 IRAR) to assess

current registry activity. This report summarizes the results of

those analyses- which indicate that 32 (63%) of the 51 grantees are

operating population-based immunization registries (Figure 1).

These 32 projects represent 49% of the U.S. population aged <6

years.
