目标.比较Pinterest平台在缓和疫苗相关搜索结果之前和之后如何描述人乳头瘤病毒（HPV）疫苗接种，以了解（1）以前的信息环境是什么样子的，以及（2）Pinterest的政策决定是否在来源和内容方面改善了这种环境。在这项定量内容分析中，我们比较了在Pinterest行动之前和之后收集的500个以HPV疫苗为重点的Pinterest帖子（“大头针”）的2个样本，以提供更可靠的疫苗相关信息。Pin图基于搜索结果，并使用健康信念模型进行分析。大多数行动前的搜索结果倾向于疫苗怀疑论，特别是关注感知的疫苗障碍。与公共卫生相关的Pinterest账户发布的大头针很少。行动后的搜索结果显示，HPV疫苗接种的好处发生了重大转变，政府或医疗账户的别针数量增加了。然而，在包含任何类型HPV内容的搜索结果中，pin的比例明显较低。Pinterest缓和疫苗接种讨论的努力基本上是成功的。然而，这项禁令似乎也限制了HPV疫苗接种的整体搜索结果，这可能会导致混乱或信息真空。
Objectives. To compare how human papillomavirus (HPV) vaccination was portrayed on Pinterest before and after the platform acted to moderate vaccine-related search results to understand (1) what the information environment looked like previously and (2) whether Pinterest's policy decisions improved this environment in terms of sources and content.Methods. In this quantitative content analysis, we compared 2 samples of 500 HPV vaccine-focused Pinterest posts ("pins") collected before and after Pinterest's actions to provide more reliable vaccine-related information. Pins were based on search results and were analyzed using the Health Belief Model.Results. The majority of preaction search results leaned toward vaccine skepticism, specifically focused on perceived vaccine barriers. Few pins were published by public health-related Pinterest accounts. Postaction search results showed a significant shift to HPV vaccination benefits, and the number of pins by government or medical accounts increased. However, the proportion of pins in search results containing HPV content of any type was significantly lower.Conclusions. Pinterest's efforts to moderate vaccination discussions were largely successful. However, the ban also appeared to limit HPV vaccination search results overall, which may contribute to confusion or an information vacuum.
