Solution Preview

Vaccines have been highly effective in generating protective immunity against infectious agents. However, their use against cancer has been generally disappointing. Vaccines can be exogenous or endogenous. Exogenous vaccines involve introducing preselected antigens on antibody delivery vehicles targeted to dendritic cells, encoded in viral vectors, or introduced as peptides in a suitable adjuvant and carrier. Their failure in treatment of cancers could have been a result of deficiencies at various steps. It may result from poor selection of antigens that were unable to generate protective T cells, suboptimal delivery ...
