Nyhan B et al. – Perceptions of flu vaccine attitudes among health discussants were strongly related to vaccination intent and beliefs about flu vaccine safety among survey respondents.

• Ordered logistic regression analysis was conducted of data collected from 1,019 undergraduates at a large public university in 2009 and 2010.

• Having health discussion networks that support vaccination is a significant predictor of beliefs of H1N1 vaccine safety (adjusted odds ratio [aOR] = 2.31) and intention (aOR = 1.86) in 2009 and of influenza vaccine safety (aOR = 1.86) and intention (aOR = 1.80) in 2010.
• These relationships are strongest among parents, friends, and spouses.
