ABSTRACT

Vaccination has played a critical role in preventing infectious diseases, resulting in the global eradication of terrible diseases such as smallpox and the near abolition of polio. This study investigates the historical evolution of vaccination, the processes by which vaccines stimulate the immune system, and the various vaccine types now in use. Furthermore, the advantages of vaccination, such as herd immunity and lower healthcare expenditures, are explored. Despite these advantages, vaccination programs confront several problems, including disinformation, vaccine reluctance, and new diseases. The study continues by underlining the importance of ongoing worldwide efforts in vaccine development and administration to prevent the comeback of vaccine-preventable diseases and address emerging infectious risks.

Keywords: Vaccination, Immunization, Infectious diseases, Herd immunity, Vaccine-preventable diseases.
