Embodiment 1
[0054] (freeze-dried influenza HA vaccine preparation)
[0055] Sucrose (manufactured by Wako Pure Chemical Industries, Ltd.) listed in Table 1 was added to influenza HA antigen (type A H1N1: A / California / 07 / 2009, manufactured by Osaka University Institute of Microbial Diseases), and PBS with the following composition was added (Phosphate-buffered sodium chloride solution), an aqueous solution containing influenza vaccine antigen was prepared in such a way that it became 20w / v% sucrose, 500 μg HA / mL influenza HA antigen (400 parts by weight of sucrose relative to 1 part by weight of influenza HA antigen). 10 μL of the obtained aqueous solution containing influenza vaccine antigen was dispensed into a 1.5 mL centrifuge tube (safe-lock tube) (manufactured by Eppendorf), and freeze-dried.

Abstract
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.
Description
technical field [0001] The present invention relates to dry formulations containing influenza vaccine antigens. More specifically, the present invention relates to a dried influenza vaccine preparation capable of stably maintaining the activity of influenza vaccine antigens even when stored without strict low temperature control, and capable of being supplied stably. Moreover, this invention relates to the manufacturing method of this influenza vaccine dry preparation. Background technique [0002] Influenza is a kind of acute infectious disease caused by influenza virus. The incubation period from influenza virus infection until the onset of influenza is usually 1 to 2 days. When you get sick, you will have a fever of 38 degrees or higher, and in addition to general symptoms such as general fatigue, headache, joint pain, and muscle pain, you will also have symptoms such as sore throat, cough, and nasal discharge. Usually recovers within 1 week. For influenza, the elderl...
