Misperceptions about influenza vaccination among parents of healthy young children.

A survey was administered to 828 parents from metropolitan Denver, Colorado, and 57% responded. Of the respondents, 47% thought their child was unlikely to contract influenza, 70% thought influenza vaccine could cause influenza, and 21% considered influenza vaccination unsafe for a 1-year-old child. The influenza immunization rate in children of surveyed parents was 71%. In multivariate analyses, the perception that influenza vaccination was the social norm was positively associated with immunization (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.03-1.69), and anticipating immunization barriers was negatively associated with immunization (OR, 0.68; 95% CI, 0.49-0.95). Parents of young children hold a number of misperceptions about influenza disease and vaccination. Despite this, high immunization rates are achievable in this population.
