The role of social networks in influenza vaccine attitudes and intentions among college students in the Southeastern United States.

PURPOSE To investigate whether support for vaccines among one's health discussants is associated with beliefs in vaccine safety and intention to vaccinate among college students. METHODS Ordered logistic regression analysis was conducted of data collected from 1,019 undergraduates at a large public university in 2009 and 2010. RESULTS Having health discussion networks that support vaccination is a significant predictor of beliefs of H1N1 vaccine safety (adjusted odds ratio [aOR] = 2.32) and intention (aOR = 1.78) in 2009 and of influenza vaccine safety (aOR = 1.85) and intention (aOR = 1.74) in 2010. These relationships are strongest among parents, friends, and spouses. CONCLUSIONS Perceptions of flu vaccine attitudes among health discussants were strongly related to vaccination intent and beliefs about flu vaccine safety among survey respondents.
