  • Patent number: 6793928
    Abstract: The present invention relates to a vaccine containing at least one particulate immunogen and an adjuvanting amount of B subunits of heat-labile enterotoxin characteristic of E. Coli. More in particular, this invention relates to vaccines wherein the adjuvanting LTB is free from contaminating A subunits or holotoxin. To this end, preferably, use is made of LTB prepared by recombinant DNA techniques. The particulate immunogens can relate to or can be derived from e.g. viruses, bacteria or fungi. This vaccine is particularly suitable for the induction of a protective response against said particulate immunogen upon mucosal (e.g. intra-nasal) administration. It was found that such administration results in both systemic and mucosal protection against the pathogen to which the particulate immunogen relates.
