Influenza Vaccination Among US Children With Asthma, 2005–2013

BACKGROUND: Children with asthma face higher risk of complications from influenza. Trends in influenza vaccination among children with asthma are unknown. METHODS: We used 2005-2013 National Health Interview Survey data for children 2 to 17 years of age. We assessed, separately for children with and without asthma, any vaccination (received August through May) during each of the 2005-2006 through 2012-2013 influenza seasons and, for the 2010-2011 through 2012-2013 seasons only, early vaccination (received August through October). We used April-July interviews each year (n = 31,668) to assess vaccination during the previous influenza season. Predictive margins from logistic regression with time as the independent and vaccination status as the dependent variable were used to assess time trends. We also estimated the association between several sociodemographic variables and the likelihood of influenza vaccination. RESULTS: From 2005 to 2013, among children with asthma, influenza vaccination receipt increased about 3 percentage points per year (P \u3c .001), reaching 55% in 2012-2013. The percentage of all children with asthma vaccinated by October (early vaccination) was slightly above 30% in 2012-2013. In 2010-2013, adolescents, the uninsured, children of parents with some college education, and those living in the Midwest, South, and West were less likely to be vaccinated. CONCLUSIONS: The percentage of children 2 to 17 years of age with asthma receiving influenza vaccination has increased since 2004-2005, reaching approximately 55% in 2012-2013
