Influenza vaccination among workers—21 U.S. states, 2013

Background Influenza illnesses can result in missed days at work and societal costs, but influenza vaccination can reduce the risk of disease. Knowledge of vaccination coverage by industry and occupation can help guide prevention efforts and be useful during influenza pandemic planning. Methods Data from 21 states using the 2013 Behavioral Risk Factor Surveillance System industry-occupation module were analyzed. Influenza vaccination coverage was reported by select industry and occupation groups, including health care personnel (HCP) and other occupational groups who may have first priority to receive influenza vaccination during a pandemic (tier 1). The t tests were used to make comparisons between groups. Results Influenza vaccination coverage varied by industry and occupation, with high coverage among persons in health care industries and occupations. Approximately half of persons classified as tier 1 received influenza vaccination, and vaccination coverage among tier 1 and HCP groups varied widely by state. Conclusions This report points to the particular industries and occupations where improvement in influenza vaccination coverage is needed. Prior to a pandemic event, more specificity on occupational codes to define exact industries and occupations in each tier group would be beneficial in implementing pandemic influenza vaccination programs and monitoring the success of these programs.
