The purpose of the present invention is to provide the following: a dried influenza vaccine preparation with which stable retention of the activity of influenza vaccine antigen is possible, even when the preparation is stored without strict low-temperature management, and with which a stable supply is possible and a method for producing the dried influenza vaccine preparation. The present invention provides a dried influenza vaccine preparation comprising influenza vaccine antigen and a disaccharide, wherein the disaccharide is one or more selected from the group consisting of sucrose, maltose, palatinose, melibiose, isomalt, cellobiose, allolactose, isomaltose, sophorose, lactobionic acid, laminaribiose, xylobiose, turanose, gentiobiose, rutinose, kojibiose, nigerose, robinose, neohesperidose, sucralose, and maltitol.本發明之目的在於提供一種流感疫苗乾燥製劑,其即便未嚴格地進行低溫管理而保存亦可穩定地維持流感疫苗抗原之活性且可穩定地供給,且提供一種該流感疫苗乾燥製劑之製造方法。本發明係一種流感疫苗乾燥製劑,其係含有流感疫苗抗原、與二糖者,且上述二糖為選自由蔗糖、麥芽糖、巴拉金糖、蜜二糖、異麥芽酮糖醇(isomalt)、纖維雙糖、異乳糖、異麥芽糖(isomaltose)、槐二糖、乳糖酸、海帶二糖、木二榶、松二糖、龍膽二糖、芸香糖、麴二糖、黑麯黴糖、刺槐糖、新橙皮糖、蔗糖素及麥芽糖醇所組成之群中之1種以上。
