Vaccinology and Immunizations is a thorough resource on the immune system, the history of vaccines, vaccine preparation, the process of vaccine approval, and the prevention and eradication of diseases. It also includes chapters on vaccine safety and errors, and complete information on pediatric and adult immunizations. There is also discussion on elderly immunology and immunization for people who are seeking to travel abroad, as well as timely information about COVID-19. Its focus on the innate and adaptive defense systems of the body will ensure understanding of human immunity and how immunizations are effective. There is a variety of available titles related to vaccinology and immunizations, but many are now outdated. Vaccinology and Immunizations provides a new, updated resource that is widely needed, and will be welcomed by students of undergraduate, graduate and master level in vaccinology or immunology, and would also be of interest to nurses, researchers, and pharmacists.
