Characteristics associated with seasonal influenza vaccination of preschool children--Oregon, 2006-2008.

Starting with the 2010-11 influenza season, the Advisory Committee on Immunization Practices (ACIP) recommended that all children aged ≥6 months be vaccinated against influenza annually, and that previously unvaccinated children aged ≤8 years be given 2 doses of vaccine. The American Academy of Pediatrics (AAP) also recommends influenza vaccinations for this population. Throughout influenza seasons, preschool children often have higher rates of influenza-related hospitalization than any other age group except older adults. To estimate influenza vaccination coverage and identify sociodemographic and health-care usage correlates of influenza vaccination status among children aged 2 years, data from the 2006-2008 Oregon Pregnancy Risk Assessment Monitoring Survey follow-back survey (Oregon PRAMS-2) were analyzed. This report summarizes the results. In Oregon, 37.7% of mothers reported that their children had received an influenza vaccination during the most recent influenza season. Factors positively associated with recent influenza vaccination in the multivariable-adjusted model were children's influenza vaccination in the previous year, children's receipt of all recommended immunizations, children's uninterrupted health insurance coverage, and mothers' unmarried status. The only factor negatively associated with vaccination was use of a family doctor rather than a pediatrician for well-child visits. The concern about vaccinations most commonly identified by mothers of children who had not received an influenza vaccination during the most recent influenza season (33.9%) was the opinion that too many shots are given at a time. This report highlights the need for health-care provider-based and community-based strategies to increase influenza vaccination coverage for children in Oregon.
