Immunopotentiators in Modern Vaccines

Immunopotentiators in Modern Vaccines, Second Edition, provides in-depth insights and overviews of the most successful adjuvants, those that have been included in licensed products, also covering the most promising technologies that have emerged in recent years. In contrast to existing books on the subject, the chapters here provide summaries of key data on the mechanisms of action of the individual vaccine adjuvants.

In addition, the book covers key aspects of how the technologies might be further developed and what might be their limitations, while also giving an overview of what made the most advanced adjuvant technologies successful.

• Provides contributions from leading international authorities in the field
• Features immunopotentiators classified by function, with well-illustrated, informative figures presenting the interaction between the immunopotentiators and the host immune system
• Lists advantages and potential hurdles for achieving a practical application for each specific immunopotentiator
• Offers US FDA perspectives which highlight how future adjuvants will be approved for new generation vaccines

Immunologists, virologists, microbiologists, oncologists, neuroscientists, and academics working in vaccinology. professionals and academics working in vaccinology who want up-to-date information about the mechanisms of modern immunopotentiators and their potential use in future rational vaccine design, decision makers and researchers in the field of vaccinology, policy makers, registration officers, marketing managers and students in the biomedical field
