Data are the percent of Vaccines for Children (VFC) enrolled providers that had assessments of their immunization coverage rates as part of the Assessment, Feedback, Incentives, and eXchange (AFIX) process.
A provider site is a service delivery location that maintains permanent records, excluding temporary locations or mobile immunization clinics or fairs and the like. Well-child clinics and immunization-only clinics in the same location were counted as separate sites only if they maintain separate sets of records.
Public providers include health department clinics, community/migrant health centers, Indian Health Service/Tribal health clinics, or other public providers (e.g., any other public clinic that provides immunizations, such as a county medical center outpatient clinic).
Private providers are individual or group primary care or pediatric practices and may include providers for which some or all of their clients are members of different managed care plans or managed care organizations. A public provider assessment is an assessment that includes a review of a random sample (or 100 percent) of immunization records. The assessment may have been conducted by project, clinic, or contractual personnel. A private provider assessment is an assessment that includes a review of immunization records either through a manual sample or through the use of an immunization registry. The assessment may have been conducted either by immunization project staff, through a contractual agreement that provides this service, or by the provider itself, in cooperation with the immunization project staff.
