This invention provides a family of immunogenic compositions and vaccines, each containing a target antigen or antigen mixture, and an oligopeptide adjuvant, exemplified by the tripeptide Ile-Glu-Trp. The adjuvant has a low side effect profile, and may be especially effective in generating a rapid and specific Th1 or cellular immune response where the antigen is poorly immunogenic, or the patient is elderly or immunocompromised. In some circumstances, effectiveness of the vaccine can be substantially enhanced by administering follow-on injections of the tripeptide alone. The vaccine has been used to generate an enhanced response to multiple strains of influenza simultaneously, and is suitable for preventing or treating other infectious and disease conditions.
本发明提供了一系列免疫原组合物和疫苗,每种组合物和疫苗均包含目标抗原或抗原混合物以及寡肽佐剂,例如三
肽Ile-Glu-Trp。该佐剂具有低副作用特性,并且在抗原免疫原性较差或患者年龄较大或免疫功能受损时,可能特别有效地产生快速和特异的Th1或细胞免疫应答。在某些情况下,通过单独注射三肽可以显著增强疫苗的有效性。该疫苗已被用于同时增强对多种流感菌株的免疫应答,并适用于预防或治疗其他传染性和疾病条件。
