Timeliness of 2009 H1N1 vaccine coverage in a low-income pediatric and adolescent population

Abstract Despite being at highest risk for 2009 H1N1 virus morbidity and mortality, many children were not immunized with the vaccine. Identification of factors that put certain children at higher risk for under-immunization could reveal populations who may need to be specifically targeted for vaccination interventions in future pandemics. Little is known about the prevalence of, or factors associated with, 2009 H1N1 vaccine coverage in low-income, urban pediatric populations. This study evaluated 2009 H1N1 vaccination coverage in 19,643 children aged 6 months to 18 years receiving care at one of five community clinics associated with an academic medical center in a low-income community. Any (≥1 dose) and full coverage (1 dose for children ≥10 years old, 2 doses for those
