To examine illness/vaccination perceptions of and intentions to vaccinate for seasonal influenza (SI) and 2009 H1N1 in the college setting.
1190 adults [M=23.5 years (SD=9.5)] from a university in the North-Eastern U.S.
We deployed a web-based survey via campus email just prior to the 2009 H1N1 vaccine release.
Younger adults (18-24 years) had lesser understanding of the difference between influenza types, and they reported less regular and current SI vaccination compared to older adults (25-64 years). Younger respondents perceived lesser likelihood of illness from, but attributed greater severity to H1N1 versus SI. Regularity of SI vaccination and perceived vaccine efficacy were the strongest predictors of intent to vaccinate against H1N1, followed by perceived likelihood of illness and confidence in what experts know about vaccine safety.
Young adults in college may require additional information during novel influenza pandemics. Measuring perceptions and past vaccination behaviors may facilitate targeting of preventive efforts in the college setting.
调查大学生对季节性流感（SI）和2009年甲型H1N1流感的患病/疫苗接种认知以及接种意愿。
来自美国东北部一所大学的1190名成年人[平均年龄M = 23.5岁（标准差SD = 9.5）]
在2009年甲型H1N1流感疫苗发布前夕，我们通过校园邮件开展了一项基于网络的调查。
较年轻的成年人（18 - 24岁）对流感类型差异的了解较少，与较年长的成年人（25 - 64岁）相比，他们报告的季节性流感定期接种和当前接种情况较少。较年轻的受访者认为感染H1N1流感的可能性较小，但认为H1N1流感比季节性流感的严重程度更高。季节性流感疫苗接种的规律性和感知到的疫苗效力是接种甲型H1N1流感疫苗意愿的最强预测因素，其次是感知到的患病可能性以及对专家所了解的疫苗安全性的信心。
在新型流感大流行期间，大学生可能需要更多信息。衡量认知和过去的疫苗接种行为可能有助于在大学环境中针对性地开展预防工作。
