Healthy Trends: Immunizations

National Data

Healthy People 2010 identifies national health objectives for the year 2010.

Data 2010 finds the latest data for each objective. Search Data 2010 by objective number: e.g., 14-04 or 27-13, where the first number refers to one of 28 chapters or “focus areas” and the second refers to the objective number within the focus area.

Examples of immunization data from these sources:

State Data

CDC’s National Immunization Program will link you to multiple sources that provide national, state and local data on the number of people who have received vaccines.

Example of state immunization data from this site:

In 2002, 91.1% of children in the District of Columbia received at least one dose of varicella vaccine between 12 and 35 months of age compared to 59.2% of children in Montana. (2002 National Immunization Survey)

State Immunization Profiles provide links to profiles on immunization coverage for all 50 states and the District of Columbia.

Example of data from the Alabama state profile:

Eighty-two percent of public and private provider sites in Alabama are enrolled in the state immunization registry. In 2001, the state received about $4 million in federal immunization funding.


Health Plan Data

HEDIS or the Health Plan Employer Data and Information Set measures the performance of commercial, Medicaid and Medicare managed care organizations (MCOs) to allow consumers to compare MCOs. The National Committee for Quality Assurance’s annual State of Health Care Quality report provides an overview of MCOs’ performance. Immunization data from this report is provided below
