ABSTRACT:
A non-toxic mucosal adjuvant is provided which may be admixed with further antigens to provide a vaccine administrable to mucosal surfaces in organisms including man. Preferably, the non-toxic mucosal adjuvant is a detoxified mutant of a bacterial ADP-ribosylating toxin, optionally comprising one or more amino acid additions, deletions or substitutions.
