Vaccination rates among underserved populations can be improved with a program that provides close individual follow up. A project led by Surabhi Vora, MD, MPH, Pediatric Immunization Program (PIP) Staff, Department of Pediatric Infectious Diseases, University of Chicago, set out to achieve at least 90% on-time adherence to AAP/ACIP immunization recommendations for parts of Chicago's inner-city. Of the 188 children enrolled to date, about 90% are up-to-date with immunizations based on AAP/ACIP guidelines. "This compares with a rate of 69.1% for the City of Chicago, as established by the 2002 NIS for 19-35 month olds, and 56% for African-American children at 13 months of age," said Dr. Vora.
