The Private Provider Assessments in Indiana report summarizes the results of 502 assessments of immunization practices completed in the private health care sector for 2001. The assessments were conducted from January through December 2001 in private provider practices including single and multiple physician practices who were enrolled in the Vaccines for Children (VFC) Program. In the 502 assessments, there were 35 sites who received more than one Clinical Assessment Software Application-based (CASA) assessment during the calendar year of 2001.
In order to be considered completely immunized by age two, each child must have received 4 vaccinations for diphtheria, tetanus, and acellular pertussis (DTaP), 3 vaccinations for polio, the first measles, mumps and rubella vaccine (MMR), at least 3 vaccinations for Haemophilus influenzae type b (Hib), and 3 vaccinations for hepatitis B (Hep B). The data contained in the report represents the immunization coverage levels of children who were 24 to 35 months of age at the time of the assessment.
