Provided are surprisingly effective methods for inactivating pathogens, and for producing highly immunogenic vaccine compositions containing an inactivated pathogen rendered noninfectious by exposure to a Fenton reagent, or by exposure to a Fenton reagent or a component thereof in combination with a methisazone reagent selected from the group consisting of methisazone, methisazone analogs, functional group(s)/substructure(s) of methisazone, and combinations thereof. The methods efficiently inactivate pathogens, while substantially retaining pathogen antigenicity and/or immunogenicity, and are suitable for inactivating pathogens, or for the preparation of vaccines for a wide variety of pathogens with genomes comprising RNA or DNA, including viruses and bacteria. Also provided are highly immunogenic inactivated vaccine compositions prepared by using any of the disclosed methods, and methods for eliciting an immune response in a subject by administering such vaccine compositions.
本发明提供了令人惊奇地有效灭活病原体的方法,以及生产高免疫原性疫苗组合物的方法,该疫苗组合物含有通过暴露于芬顿试剂或通过暴露于芬顿试剂或其组分与选自甲异嗪、甲异嗪类似物、甲异嗪的官能团/亚结构及其组合的甲异嗪试剂组合而变得无传染性的灭活病原体。这些方法可有效灭活病原体,同时基本保留病原体的抗原性和/或免疫原性,适用于灭活病原体或制备疫苗,用于包括病毒和细菌在内的多种具有 RNA 或 DNA 基因组的病原体。此外,还提供了通过使用所公开的任一方法制备的高免疫原性灭活疫苗组合物,以及通过施用此类疫苗组合物激发受试者免疫应答的方法。
