OBJECTIVE: In 2002, the Advisory Committee on Immunization Practices recommended universal influenza vaccination of 6- to 23-month-olds. Little is known about coverage and missed opportunities for influenza vaccination at inner-city practices. The objective of this study was to assess the 2000-2001 to 2004-2005 coverage and the prevalence of missed opportunities for influenza vaccination among inner-city children. METHODS: We conducted a retrospective review for the 2000-2001 to 2004-2005 influenza seasons at a practice network in New York City. The study population included 5 annual cohorts of 6- to 29-month olds as of March 31 of each year with > or = 1 visit to the network in the previous 12 months (n = 7063). Immunization data were obtained from the network registry and the New York Citywide Immunization Registry. Coverage levels were estimated for 1 dose (partial) and 2 doses (full). Missed opportunities were assessed for visits within each influenza season. RESULTS: Coverage rose steadily throughout the 5 years (full: 1.6% to 23.7%; partial: 1.5% to 18.1%). The relationship between year and coverage was linear. Missed opportunities occurred in 82% of visits and were more common for first (89%) than for repeat doses (38%). Missed opportunities per child per season decreased from 2.9 to 2.0 during the study period. CONCLUSIONS: Influenza vaccine coverage among 6- to 23-month-olds at inner-city practices increased steadily from 2000-2001 through 2004-2005, and the prevalence of missed opportunities per child decreased. However, coverage remained suboptimal, with most of children not vaccinated or undervaccinated. Missed opportunities were major contributors to low coverage.
