摘要

The present application discloses methods for stimulating or enhancing an immune response of a subject to protect against an infection caused by an agent selected from Hepatitis B Virus (HBV), avian influenza virus, the bacterium Bacillus anthracis or the bacterium Streptococcus pneumoniae, the method comprising administering to said subject a combination of sphingoid-polyalkylamine conjugate and a biologically active molecule, the combination being effective to provide said stimulation or enhancement of the immune response. Also disclosed are vaccines comprising a combination of the sphingoid-polyalkylamine conjugate and a biologically active molecule for stimulating or enhancing an immune response of a subject to protect against an infection caused by such an agent. Preferred conjugates are N-palmitoyl D-erythro sphingosyl-1-carbamoyl spermine (C-1 CCS), N-palmitoyl D-erythro sphingosyl-3-carbamoyl spermine (C-3 CCS) and mixtures thereof. Also disclosed are uses of C-3 CCS for various applications.
