title: Factors associated with receipt of 2009 pandemic influenza A (H1N1) monovalent and seasonal influenza vaccination among school-aged children: Maricopa County, Arizona, 2009-2010 influenza season.
abstract: BACKGROUND
  To target school-aged children (SAC), who were identified as a priority for pandemic 2009 Influenza A (pH1N1) vaccination, Maricopa County (MC) initiated school-based influenza vaccination in 69% of its 706 schools during the 2009-2010 influenza season.
  
  
  OBJECTIVE
  To determine factors associated with receipt of pH1N1 monovalent and 2009-2010 seasonal influenza vaccination among SAC and evaluate the association of school-based vaccination with vaccination status of SAC.
  
  
  METHODS
  Random-digit dialing was used to survey 600 MC households with willing adult participants and children grades K-12. Logistic regression was used to identify factors associated with pH1N1 and seasonal vaccine receipt.
  
  
  METHODS
  Arizona.
  
  
  METHODS
  Household adults with children grades K-12.
  
  
  METHODS
  Characteristics of children, parents, and households were obtained.
  
  
  RESULTS
  Among 909 SAC, 402 (44%) received pH1N1 and 436 (48%) received seasonal vaccination. Factors associated with pH1N1 vaccination included vaccine availability at school (adjusted odds ratio [AOR]: 1.6; 95% confidence interval [CI]: 1.0-2.7), high-risk medical condition in child (AOR: 2.4; 95% CI: 1.4-4.0), elementary versus high school attendance (AOR: 1.6; 95% CI: 1.0-2.7), and seasonal influenza vaccination (AOR: 10.0; 95% CI: 6.4-15.6). Factors associated with seasonal vaccination included Hispanic ethnicity (AOR: 2.2; 95% CI: 1.1-4.2), health insurance coverage (AOR: 4.8; 95% CI: 1.7-13.7), elementary versus high school attendance (AOR: 1.5; 95% CI: 1.0-2.5), and pH1N1 vaccination (AOR: 10.5; 95% CI: 6.7-16.6).
  
  
  CONCLUSIONS
  Availability of pH1N1 vaccine at school was independently associated with pH1N1 vaccination of MC school-aged children. School-based influenza vaccination campaigns should be considered to increase vaccination among this population.
