National efforts have been directed toward the reduction of vaccine preventable diseases through improved immunization rates. The purpose of this study was to determine the
immunization status of a rural childhood population. Percent of children with up-to-date immunization series and individual antigens was calculated at the ages of 12 and 24 months, and school entry. Percent of children with age appropriate immunization series was calculated at the ages of 3, 5, 7, 16, and 19 months, and school entry. Data were compiled using
school-based Certification of Immunization Records of 122 kindergarten students in a rural school district in northwestern Pennsylvania.
