How do vaccination programs prevent the spread of infectious diseases, protect population health, and contribute to disease eradication efforts?

Vaccination programs involve administering vaccines to individuals to stimulate their immune systems to produce protective antibodies against specific pathogens. Vaccines confer immunity to infectious diseases such as measles, polio, influenza, and COVID-19, reducing transmission rates, morbidity, and mortality. Vaccination campaigns, herd immunity, and international cooperation are critical for controlling outbreaks, preventing epidemics, and achieving global health goals.
