Influenza vaccines containing insoluble particulate adjuvants have been found to elicit an IgG response that is primarily a TH2 response (IgG1). This response can be shifted towards a TH1 response (IgG2a) by including immunopotentiators in the compositions. Thus the invention provides an immunogenic composition comprising: (i) an influenza virus antigen; (ii) an insoluble particulate adjuvant; and (iii) a immunopotentiator.
研究发现,含有不溶性微粒佐剂的流感疫苗引起的 IgG 反应主要是 TH2 反应(IgG1)。 通过在组合物中加入免疫
促进剂,这种反应可转向 TH1 反应(IgG2a)。 因此,本发明提供了一种免疫原组合物,其中包括:(i) 流感病毒抗原;(ii) 不溶性微粒佐剂;(iii) 免疫
促进剂。
