SARS-Co V-2, the coronavirus responsible for COVID-19, wreaked havoc on the world; it could both spread easily and mutate rapidly, leading to the decrease in the effectiveness of newly developed vaccines over time. The detection of these mutated variants and the development of more efficient vaccines requires significant effort and increased knowledge in this field. This new book, SARS-Co V-2 Variants and Global Population Vulnerability: Diagnostic Strategies, Vaccine Development, and Therapeutic Management, provides detailed and systemic information regarding the biology and immunophysiology of SARS-Co V-2 and highlights the global vulnerability of the world population to SARS-Co V-2 infection and COVID-19.The book covers different aspects pertaining to the SARS-Co V-2 variants and their relation to global vulnerability. Chapters discuss the diagnostics, vaccine development, and therapeutic management starting from the zoonotic origin, organization, and transmission of SARS-Co V-2, lifestyle and immunophysiology of the virus, detection and diagnosis techniques, and analytical techniques. The book also observes the global impact of Delta and Omicron SARS-Co V-2 variants. It looks at the drug repurposing and new drug discovery routines for the emerging variants. It presents strategies for fast-track vaccine development, the roles of nasal vaccines and nucleic acid vaccines for COVID-19 management, monoclonal antibody therapy for the diseases management, along with the use of dietary supplements and nutraceuticals, herbal drugs, and other alternative remedies for COVID-19 management. The book also considers the social and environmental impacts of SARS-Co V-2 variants and the current challenges, outlining aspects that can help in developing more efficacious means for controlling SARS-Co V-2 in the future.Key highlights: Discusses SARS-Co V-2 variants, diagnosis strategies, vaccine development, and the therapeutic management of the disease Provides comprehensive coverage of SARS-Co V-2 virus and variants With its unique and thorough take on the subject, this book is an important resource of know-how for investigators working in this area. Professionals from the pharmaceutical industry as well as students, research scholars, doctors, and other healthcare professionals will find this book of particular value.
