A similar outcome was observed in Pakistan’s Swat Valley after the militant takeover of 2009 rendered the region inaccessible for months. This month’s decision to hold back vaccination in Karachi after health workers there were threatened, though understandable, is nonetheless a cause for serious concern in this respect.
同样的局面也出现在巴基斯坦的史瓦特河谷（Swat Valley）。2009年，史瓦特河谷被军事接管，在几个月的时间里，这一地区都无法进入。由此看来，本月因卫生工作人员受到威胁而取消卡拉奇接种工作的决定虽然可以理解，但会造成严重后果。
