Which level of prevention aims to stop a disease before it ever occurs, exemplified by vaccination programs?

Answer

Primary Prevention

Primary Prevention is proactively focused on preventing the initial occurrence of a health issue entirely. Classic examples include introducing immunity through widespread vaccination programs, which stops infection before it can start. Other measures falling under this category involve foundational public health work like improving sanitation infrastructure or running large-scale health education campaigns designed to stop illness before it manifests in the population.
