DNA is a rapidly developing vaccine platform for cancer and infectious and non-infectious diseases. Plasmids are used as immunogens to encode proteins to be further synthesized in vaccine recipients. DNA is mainly synthetic, ensuring enhanced expression in the cells of vaccine recipients (mostly mammalians). Their introduction into the host induces antibody and cellular responses. The latter are often more pronounced, and mimic the events occurring in infection, especially viral. There are a few distinct ways in which the vaccine antigen can be processed and presented, which determine the resulting immune response and which can be manipulated. Routinely, the antigen synthesized within the host cell is processed by proteasome, loaded onto, and presented in a complex with MHC I molecules. Processing can be re-routed to the lysosome, or immunogen can be secreted for further presentation in a complex with MHC II. Apart from expression, vaccination efficacy depends on DNA delivery. DNA immunogens are generally administered by intramuscular or intradermal injections, usually followed by electroporation, which enhances delivery 1000-fold. Other techniques are also used, such as noninvasive introduction by biojectors, skin applications with plasters and microneedles/chips, sonication, magnetofection, and even tattooing. An intense debate regarding the pros and cons of different routes of delivery is ongoing. A number of studies have compared the effect of delivery methods at the level of immunogen expression, and the magnitude and specificity of the resulting immune response. According to some, the delivery route determines immunogenic performance; according to others, it can modulate the level of response, but not its specificity or polarity. The progress of research aiming at the optimization of DNA vaccine design, delivery, and immunogenic performance has led to a marked increase in their efficacy in large species and humans. New DNA vaccines for use in the treatment of infectious diseases, cancer, allergies, and autoimmunity are forthcoming. This Special Issue covers various aspects of DNA vaccine development.

In the early 1990s, almost 200 yr after Edward Jenner demonstrated the effectiveness of the smallpox vaccine, a new paradigm for vaccination emerged. The conventional method of vaccination required delivery of whole pathogens or structural subunits, but in this new approach, DNA or genetic information was administered to elicit an immunological response. Once it was observed that plasmid DNA delivered in vivo led to production of an encoded transgene (1), two ground-breaking studies demonstrated that immunological responses could be generated against antigenic transgenes via plasmid DNA delivered by DNA vaccination (as this approach is called) (2,3). The appe- ance of this new vaccination strategy coincided with advances in molecular biology, which provided new tools to study and manipulate the basic elements of an organism’s genome and also could also be applied to the design and production of DNA vaccines. DNA Vaccines is a major updated and enhancement of the first edition. It reviews state-of-the-art methods in DNA vaccine technology, with chapters describing DNA vaccine design, delivery systems, adjuvants, current appli- tions, methods of production, and quality control. Consistent with the approach of the Methods in Molecular Medicine series, these chapters contain detailed practical procedures on the latest DNA vaccine technology. The enthusiasm for DNA vaccine technology is made clear by the number of research studies published on this topic since the mid-1990s.

Vaccine Manufacturing and Production is an invaluable reference on how to produce a vaccine - from beginning to end - addressing all classes of vaccines from a processing, production, and regulatory viewpoint. It will provide comprehensive information on the various fields involved in the production of vaccines, from fermentation, purification, formulation, to regulatory filing and facility designs. In recent years, there have been tremendous advances in all aspects of vaccine manufacturing. Improved technology and growth media have been developed for the production of cell culture with high cell density or fermentation. Vaccine Manufacturing and Production will serve as a reference on all aspects of vaccine production by providing an in-depth description of the available technologies for making different types of vaccines and the current thinking in facility designs and supply issues. This book will provide insight to the issues scientists face when producing a vaccine, the steps that are involved, and will serve as a reference tool regarding state-of-the-art vaccine manufacturing technologies and facility set-up. Highlights include: Comprehensive coverage of vaccine production : from a process point of view- fermentation to purification to formulation developments; from a production point of view - from facility design to manufacturing; and from a regulatory point of view - requirements from government agencies Authors from different major pharmaceutical and biotechnology companies Describes the challenges and issues involved in vaccine production and manufacturing of the different classes of vaccines, an area not covered by other books currently on the market

Vaccines have made it possible to eradicate the scourge of smallpox, promise the same for polio, and have profoundly reduced the threat posed by other diseases such as whooping cough, measles, and meningitis. What is next? There are many pathogens, autoimmune diseases, and cancers that may be promising targets for vaccine research and development. This volume provides an analytic framework and quantitative model for evaluating disease conditions that can be applied by those setting priorities for vaccine development over the coming decades. The committee describes an approach for comparing potential new vaccines based on their impact on morbidity and mortality and on the costs of both health care and vaccine development. The book examines: Lessons to be learned from the polio experience. Scientific advances that set the stage for new vaccines. Factors that affect how vaccines are used in the population. Value judgments and ethical questions raised by comparison of health needs and benefits. The committee provides a way to compare different forms of illness and set vaccine priorities without assigning a monetary value to lives. Their recommendations will be important to anyone involved in science policy and public health planning: policymakers, regulators, health care providers, vaccine manufacturers, and researchers.
