This may in part be the result of shifting population, growing poverty, inadequate distribution of resources, or even complacency against personal hygiene. As a result of the low income and low standards of health in developing countries, they provide the perfect breeding grounds for the pathogens and parasites that are the root cause of Neglected Tropical diseases (NTDs). In the case of emerging diseases, most are of zoonotic origin and the recent COVID-19 pandemic is a key example. However, it is not just new diseases but re-emerging diseases such as Influenza that highlight the relentless nature of these infections. Vaccines represent the ultimate safety net against these diseases by bolstering immune systems and lowering subsequent mortality and morbidity of these conditions. In fact, against diseases with high mortalities such as AIDS, Hepatitis, and Malaria, vaccine development has markedly reduced mortality and prolonged life expectancy of those afflicted with these conditions. However, this research highlights the importance of enhancing vaccine efficacy and response. The review further underscores the necessity of research, the timing of vaccine administration, effective resource management by governments, and the perception of the population. Therefore, the review offers valuable insights for the medical community and the pharmaceutical industry in improving research and management to maximize the potential of vaccines.</p>
