答案 D
解析 词义辨析【直击答案】本空格所在句是More than three million doses were to be made available in early October 2009,though most of those 17 doses were of the FluMist nasal spray type。句意为，2009年10月初，300多万新型疫苗被予以使用，虽然这种药剂大多数是喷鼻剂特敏福。本题答案为D项initial“最初的”，意为“这种疫苗初期产品的类型是喷鼻剂”。【命题思路】本题主要考查形容词辨析和对上下文信息的把握。【干扰排除】C项innovative“创新的，革新的”有一定干扰强度，D项initial的含义是“开始的，最初的”，与上文前一句的new构成语义连接，为近义词复现。
