Abstract

Annual influenza vaccination is an effective strategy for preventing influenza. We analyzed data from the 2010-2016 National Health Interview Survey using Kaplan-Meier survival analysis to estimate the cumulative proportion of persons reporting vaccination in each of the 2010-11 through 2015-16 seasons, for persons ages ?18, 18-49, 50-64, and ?65 years, health care personnel (HCP), and pregnant women (2012-13 through 2015-16 seasons). We compared vaccination coverage by race/ethnicity within each group. Vaccination coverage among adults ?18 years increased from 38.1% in 2010-11 to 43.4% in 2015-16, with an average increase of 1.0 percentage point annually. From the 2010-11 through 2015-16 seasons, coverage was stable for adults ?65 years, and increased by 2.7-9.0 percentage points for all other subgroups examined. Coverage in 2015-16 was 70.4% for adults >65 years, 46.4% for 50-64 years, 32.3% for 18-49 years, 64.8% for HCP, and 50.3% for pregnant women. Among adults ?18 years for the 2015-16 season, coverage was significantly lower among non-Hispanic blacks and Hispanics compared with non-Hispanic whites. Targeted efforts are needed to improve coverage and reduce disparities.
