Vaccine containing B subunits of heat-labile enterotoxin (LTB) of Escherichia coli as an adjuvant

摘要

The present invention relates to a vaccine containing at least one immunogen and an adjuvanting amount of B subunits of heat-labile enterotoxin characteristic of E. coli isolated from a non-human source. This vaccine is particularly suitable for induction of a protective response against said immunogen upon mucosal (e.g. intra-nasal) administration.
