In Vaccines We Trust? The Effects of the CIA’s Vaccine Ruse on Immunization in Pakistan
研究了2011年中情局利用疫苗接种行动抓捕本·拉登事件被曝光后，塔利班借此发起反疫苗宣传，导致巴基斯坦伊斯兰支持率高的地区疫苗接种率下降23%至39%，说明抹黑疫苗的信息会损害公众对卫生服务的信任。
Abstract 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.
