The immunotargeting approach to adjuvant-independent subunit vaccine design.

Author information

Department of Immunology, University of Toronto, Canada.


Recently there has been considerable interest in exploring adjuvant-independent approaches to the enhancement of immunogenicity. One strategy which has emerged in response to this need is the immunotargeting approach to subunit vaccine design. Immunotargeting involves the conjugation of non-self antigens to monoclonal antibodies specific for cell surface determinants (e.g. class II MHC) on antigen presenting cells in vivo. Saline injections of these immunoconjugates have been shown to promote significant IgG responses to the delivered antigens in a number of different animal model studies. Oral and nasal immunizations in mice with anti-class II MHC immunoconjugates induce both secretory IgA and systemic IgG responses. Recombinant anticlass II MHC antibodies with defined B-cell and T-cell epitopes incorporated into their primary sequence have recently been used to induce epitope specific antibody responses in macaques. Thus the potential now exists for the rational design of adjuvant-independent human vaccine candidates based on a recombinant immunotargeting anti-body framework.
