Problems solved by technology

[0003] The prior art Shuangshenmiao cryopreservative contains gelatin components. Because the gelatin is derived from natural animal extracts, there are uncontrollable defects such as uncertain components and contamination by foreign substances, which makes gelatin easily cause allergic reactions.
It has been reported that some children's recipients' allergy to the MMR combination vaccine is caused by the gelatin in the vaccine producing IgE antibodies against gelatin molecules in the recipient's body; gelatin can cause both cell-mediated immune responses and acellular Mediate immune response; in addition, gelatin is also the main source of bacterial endotoxin, which can cause the human body to produce a fever reaction; therefore, there are problems and deficiencies in the prior art of allergic reactions and fever reactions

Abstract

The invention discloses a gelatin-free bivalent renal syndrome vaccine freeze-drying protective agent, and provides a formula and a preparation technology of the freeze-drying protective agent. According to the bivalent renal syndrome vaccine freeze-drying protective agent prepared from saccharose, glycine, human serum albumin, arginine, mannitol and a phosphate buffer solution, the problems and defects that in the prior art, an anaphylactic reaction and a fever reaction exist are avoided, so that for the freeze-drying protective agent of a bivalent inactivated vaccine for a hemorrhagic fever with renal syndromes, the defect of gelatin is overcome, and the purposes of eliminating the anaphylactic reaction and the fever reaction are achieved.

Description

technical field [0001] The invention relates to a freeze-drying protective agent for vaccines, in particular to a freeze-drying agent for double-kidney vaccines without gelatin components, which is used for making freeze-dried preparations of inactivated vaccines for bivalent renal syndrome hemorrhagic fever. Background technique [0002] Vaccine freeze-drying protective agent, referred to as cryoprotectant, is a protective agent added to the vaccine to prevent the sex change of the vaccine due to freeze-drying when the vaccine is made into a freeze-dried preparation; to make a bivalent renal syndrome hemorrhagic fever inactivated vaccine Freeze-drying agent for freeze-dried preparations, referred to as Shuangshenmiao cryoprotectant. [0003] The cryoprotectant for Shuangshen Miao in the prior art contains gelatin components. Since the gelatin is derived from natural animal extracts, there are uncontrollable defects such as uncertain components and contamination by exogenous...
