Data from the Behavioral Risk Factor Surveillance System was used to determine if parents’ decisions to vaccinate children against seasonal influenza conform to predictions made by theories of preventive health behavior that postulate increased preventive action with increased risk. Results indicated that parents of children with active asthma were more likely to report influenza vaccination than parents of children who never had asthma (OR = 3.5, 95% CI 2.4–5.1). There was no difference in vaccination frequency reported by parents of children without asthma and children whose asthma is in remission (OR = .8, 95% CI.4–1.4). Parents of children whose asthma is in remission will require additional education and prompting to encourage needed influenza vaccination.
