title: Assessment of undervaccinated children following a mass vaccination campaign--Kansas, 1993.
abstract: A 1992 retrospective survey by the Kansas Department of Health and Environment (KDHE) of children entering school in Kansas indicated that 52% were completely vaccinated by 24 months of age (i.e., received four doses of diphtheria and tetanus toxoids and pertussis vaccine [DTP], three doses of poliomyelitis vaccine, and one dose of measles-mumps-rubella vaccine [MMR]). In response to this low vaccination coverage rate, the KDHE set a goal for 1995 of completely vaccinating 90% of children by age 24 months. A major new initiative--Operation Immunize (OI)--undertaken to accomplish this goal consisted of three statewide vaccination campaigns on weekends during 1993-1994. This report summarizes the results of an assessment of the short-term impact of OI on children who remained undervaccinated following the first campaign.
