title: Seasonal influenza vaccination coverage among adult populations in the United States, 2005-2011.
abstract: The most effective strategy for preventing influenza is annual vaccination. We analyzed 2005-2011 data from the National Health Interview Survey (NHIS), using Kaplan-Meier survival analysis to estimate cumulative proportions of persons reporting influenza vaccination in the 2004-2005 through 2010-2011 seasons for persons aged ≥18, 18-49, 50-64, and ≥65 years, persons with high-risk conditions, and health-care personnel. We compared vaccination coverage by race/ethnicity within each age and high-risk group. Vaccination coverage among adults aged ≥18 years increased from 27.4% during the 2005-2006 influenza season to 38.1% during the 2010-2011 season, with an average increase of 2.2% annually. From the 2005-2006 season to the 2010-2011 season, coverage increased by 10-12 percentage points for all groups except adults aged ≥65 years. Coverage for the 2010-2011 season was 70.2% for adults aged ≥65 years, 43.7% for adults aged 50-64 years, 36.7% for persons aged 18-49 years with high-risk conditions, and 55.8% for health-care personnel. In most subgroups, coverage during the 2010-2011 season was significantly lower among non-Hispanic blacks and Hispanics than among non-Hispanic whites. Vaccination coverage among adults under age 65 years increased from 2005-2006 through 2010-2011, but substantial racial/ethnic disparities remained in most age groups. Targeted efforts are needed to improve influenza vaccination coverage and reduce disparities.
