Vaccinology has experienced a dramatic resurgence recently, as traditional methodologies of using attenuated live pathogens or inactivated whole pathogens have been either ineffective or are not an acceptable risk for several disease targets, including HIV and Hepatitis C. Gene-based vaccines can stimulate potent humoral and cellular immune responses, and viral vectors might be an efficient strategy for both delivery of antigen-encoding genes, as well as facilitating and enhancing antigen presentation. Vectors derived from diverse viruses with distinct tropism and gene expression strategies have been developed, and are being evaluated in preclinical and clinical vaccine studies. Virus-based vaccines represent a promising approach for vaccines against infectious and malignant disease.
