Modeling receipt of influenza A(H1N1)pdm09 vaccinations among US children during the 2009-2010 flu season: findings from the 2010 National Health Interview Survey.

Objective: Using 32 weeks of data from the 2010 National Health Interview Survey, factors associated with receipt of influenza A(H1N1)pdm09 vaccinations among US children during October 2009 through February 2010 are examined.

Methods: Logistic models estimated receipt of first dose by January 1, 2010 for all children aged 4.5 months through 17 years and receipt of second dose by February 1, 2010 for children aged 6 months through 9 years who received a first dose, using demographic characteristics and measures of family structure, parental education, family income, access to health care, and chronic condition status. All analyses were weighted to yield nationally representative results for the US child population.

Results: Receipt of a seasonal influenza vaccination in the 12 months before October 2009 as well as race/ethnicity, family structure, and various measures representing family socioeconomic status were statistically significant correlates of receipt of the first pH1N1 dose, whereas children's asthma and chronic condition status were not.

Conclusions: In the event of future pandemics, public health officials may utilize these findings to target particular segments of the US child population that may have been underserved during the 2009 influenza pandemic.
