Pandemics have not been recent. Apart from the Spanish flu and the recent COVID-19 pandemic, the ability of pathogens to target humanity is a repeated pattern over time. For instance, what was first reported in late 2019 and brought the globe to a standstill in 2020, COVID-19 is firmly etched in the minds of the survivors. Research has always pointed out vaccines as being the cornerstone approach to quelling epidemics and pandemics: along the lines of the adage "better safe than sorry". This book comes at this crucial juncture when our conquest of land and overpopulation is resulting in waves of epidemics. The book starts with groundwork entailing the impact of vaccines, their production and costs and also discusses the ethical aspects of vaccine research and also vaccines for "neglected diseases".
