Abstract.
A novel class of vaccines, based on the immunization with "naked" DNA, may hold the promise of protecting against human disease without the disadvantages associated with vaccines presently used, and may help to prevent infections which are not curable today. Direct intramuscular or intradermal inoculation of plasmid DNA encoding sequences of viral proteins results in the synthesis of these proteins, causing humoral and/or cellular immune responses in the recipient. Several advantages are associated with DNA immunization, e.g., cheap to produce, heat stability, amenable to genetic manipulation, mimic viral infection, and no risk of reversion to pathogenicity. Nevertheless, some concerns remain regarding their safety, e.g., the possible integration of plasmid DNA into host chromosomes. In summary, the results concerning the efficiency of DNA vaccination demonstrate clearly that these new vaccines may have a promising future in human immunization.
