This study provides the first quasi-experimental evidence on the effects of nonbinding vaccine recommendations targeted at high school–aged adolescents. Using data from the National Immunization Survey–Teen and the Centers for Disease Control’s disease surveillance system, I find that these simple recommendations significantly increased meningococcal vaccination rates among the targeted population by 21 percentage points, or 133 percent relative to the baseline mean, and substantially reduced meningococcal disease incidence in the population. I also provide evidence that the recommendations primarily affected vaccination rates through changes in provider behavior, and show that they exacerbated preexisting disparities in receipt of preventive care. In particular, groups with lower socioeconomic status, which had lower rates of vaccination and provider contact prior to the recommendation, were also less responsive to the policy.

给青少年提振？青少年脑膜炎球菌疫苗建议的效果

这项研究提供了针对高中生青少年的非结合疫苗推荐效果的首个准实验证据。通过使用《国家青少年免疫调查》和疾病控制中心的疾病监测系统的数据，我发现这些简单的建议将目标人群中的脑膜炎球菌疫苗接种率显着提高了21个百分点，相对于基线平均值而言，提高了133％。降低了人群中的脑膜炎球菌病发病率。我还提供了证据，表明这些建议主要通过提供者行为的变化影响了疫苗接种率，并表明它们加剧了在接受预防保健方面的既往差距。特别是社会经济地位较低的群体，
