Metabolomics for Personalized Vaccinology provides insight into the importance of personalized vaccines in the clinical and research environments. It explores the development of personalized vaccines, which requires in-depth knowledge of the patient’s health status, particularly the immune system, and on metabolomics, the closest indicator of the disease phenotype. Specifically, the book provides an understanding of how metabolomics might be employed in personalized vaccinology and how the metabolic pathway of the host’s system is altered by vaccine administration. Over the past few years, researchers have published articles on personalized vaccines, but these are sparse. Therefore, compiling information on this topic gives the reader an overview of the progress of the field, despite being at its infancy. Metabolomics for Personalized Vaccinology is ideally suited for researchers and postgraduate students who are interested in clinical and nonclinical studies where metabolites are used for the identification of disease and therapeutic targets.
