| abstract |
An immunogenic agent suitable for preventing, treating or immunizing against one or a plurality of different pathogen comprises an immunogenic agent which comprises one or a plurality of pathogen-derived proteins, fragments, variants or derivatives thereof displayed on a lipid vesicle and a carrier protein such as diptheria toxoid located in an intravesicular space. The immunogenic agent may be suitable for intranasal administration and may be capable of eliciting a mucosal immune response. The immunogenic agent may further comprise an activator of innate immunity such as trehalose-6,6'-dibehenate and/or a bile salt such as sodium deoxycholate. The one or plurality of pathogens may be group A streptococcus, viruses or hookworms. |
