In July 2011, the Pakistani public learnt that the Central Intelligence Agency (CIA) had used a vaccination campaign as cover to capture Osama Bin Laden. The Taliban leveraged on this information and launched an anti-vaccine propaganda campaign to discredit vaccines and vaccination workers. We evaluate the effects of these events on immunization by implementing a difference-in-differences strategy across cohorts and districts. We find that vaccination rates declined between 23% and 39% in districts in the 90th percentile of Islamist support relative to those in the 10th percentile. These results suggest that information discrediting vaccination campaigns can negatively affect trust in health services and demand for immunization.

在我们信任的疫苗中？中央情报局的疫苗诡计对巴基斯坦免疫接种的影响

2011 年 7 月，巴基斯坦公众获悉，中央情报局 (CIA) 以疫苗接种运动为掩护抓捕奥萨马·本·拉登。塔利班利用这些信息发起了一场反疫苗宣传运动，以诋毁疫苗和疫苗接种工作人员。我们通过跨队列和地区实施差异化策略来评估这些事件对免疫接种的影响。我们发现，相对于 10% 的地区，伊斯兰支持率 90% 的地区的疫苗接种率下降了 23% 到 39%。这些结果表明，诋毁疫苗接种运动的信息会对卫生服务的信任和免疫需求产生负面影响。
